Schneider XS630B1MAL2 OsiSense XS M30 General Purpose Inductive Proximity Sensor, 2-Wire Discrete Output, 24-240V AC/DC — Specifications, Setup, and Selection Guide

If you are specifying or replacing an M30 inductive proximity sensor on an assembly line, conveyor, or machine tool and you have landed on the Schneider XS630B1MAL2, you are likely weighing one question above all others: does this single part number cover your voltage environment and survive your installation conditions? The answer is yes — provided your detection gap is 12mm or less, your target is ferrous metal, and you need a discrete normally open output. The XS630B1MAL2 is a 2-wire OsiSense XS M30 cylindrical sensor rated for 24-240V AC/DC with an IP68/IP69K dual environmental certification and a 15mm nominal sensing distance, making it one of the more versatile single-SKU options in the OsiSense XS family.

Who Should Buy the XS630B1MAL2 — and Who Should Not

This sensor is the right choice when all of the following are true for your application:

  • Your mounting cavity is threaded M30 x 1.5 and accepts a 62mm cylindrical body with 52mm threaded engagement depth
  • Your supply voltage is within the 20-264V AC/DC operating window — covering both legacy 110V/240V AC systems and modern 24V DC PLC platforms without additional adapters
  • Your required detection gap between sensor face and target object is 12mm or less — the reliable operating zone, not the 15mm nominal value
  • Your target material is ferrous metal — the inductive detection principle does not apply to aluminum, copper, or other non-ferrous materials
  • Your PLC input card accepts a 2-wire normally open discrete signal and your wiring logic is built around NO configuration
  • Your environment involves washdown, moisture, dust, or high-pressure spray where IP68/IP69K protection is required

If your application requires sensing distances beyond 15mm, a PNP or NPN logic output, an M18 or M12 form factor, or non-ferrous metal detection, this model is not the correct choice. The XS7 series covers sensing distances up to 60mm, and PNP/NPN variants exist within the OsiSense XS family for modern 24V DC PLC architectures.

What the XS630B1MAL2 Does in a Working Automation System

The XS630B1MAL2 is a 2-wire inductive proximity sensor that generates a binary discrete signal — output energized or output off — when a ferrous metal object enters or leaves the detection zone in front of the sensor face. It operates without physical contact, using a magnetic field to sense the presence of metal within the 0-12mm operating zone. The single normally open (NO) output is wired directly into a PLC input terminal or control circuit, providing the on/off trigger that drives counting logic, position verification, or interlock conditions.

What distinguishes this model from narrower-range alternatives is its 24-240V AC/DC rated supply, which allows a single sensor SKU to function across both legacy relay-logic and AC contactor panels running at 110V or 240V and contemporary 24V DC PLC architectures. A yellow LED on the sensor body reflects output state in real time, providing immediate visual feedback during commissioning and fault-finding without test equipment. The M30 x 1.5 threaded cylindrical body with flush-mount (shielded) configuration allows recessed installation into machine frames and brackets, protecting the sensor face from mechanical damage in high-traffic production environments.

The XS630B1MAL2 is not a networked or intelligent device — it produces no analog signal, no IO-Link communication, and no diagnostic data stream. Its value is exactly that simplicity: a verified, reliable binary presence signal that integrates into virtually any control system wired in the last four decades.

Typical System Architecture for M30 Proximity Sensor Deployment

The XS630B1MAL2 sits at the field level of the control architecture, acting as the raw detection point between the physical machine and the PLC's discrete input module. Understanding its position in the signal chain is essential before mounting and wiring.

  • Power supply (24V DC or 110-240V AC) feeds the sensor's 2m pre-attached cable directly, with one conductor routed through the PLC input terminal to complete the detection circuit
  • The XS630B1MAL2 is installed flush into an M30 x 1.5 threaded cavity in the machine frame, bracket, or proximity mounting rail, with the detection face oriented perpendicular to the target's approach path
  • Ferrous metal target (part, actuator, flag, or cam) passes through or stops within the 0-12mm operating zone in front of the sensor face
  • The NO output closes when metal is detected, pulling the PLC input terminal high; the PLC program reads this discrete bit to trigger counting, interlocking, or positioning logic
  • The yellow LED on the sensor body reflects the same output state as the PLC input bit, giving technicians a local visual reference for confirming signal status during commissioning or troubleshooting

Typical Applications and Deployment Scenarios

Metal part presence detection on assembly lines is the most common deployment for the XS630B1MAL2. A sensor mounted at a workstation detects whether a ferrous part is seated in the fixture before the PLC enables the next operation — providing a binary go/no-go gate that prevents operations from running on an empty station.

Position sensing for actuators, cylinders, and indexing mechanisms is a second high-frequency use case. The sensor is mounted at the stroke end of a pneumatic or hydraulic actuator, with a ferrous flag or cam attached to the moving rod. When the actuator reaches full extension or full retraction, the flag enters the 0-12mm zone and the sensor fires, confirming position to the PLC.

Object counting and sorting on conveyor systems leverages the 500Hz switching frequency in DC mode, allowing reliable pulse detection of ferrous parts moving through the detection zone at production line speeds. The IP68/IP69K rating makes the XS630B1MAL2 appropriate for food and beverage conveyors where washdown cleaning is routine, and for pharmaceutical packaging lines where contamination control requires regular high-pressure spray cycles.

Safety interlock confirmation — detecting whether a machine guard, gate, or door has a ferrous target aligned with the sensor — is a fourth application where the 2-wire discrete NO output matches the wiring architecture of most safety relay input circuits. The -25 to 70°C operating temperature range extends the sensor's applicability to cold-storage facilities and outdoor installations as well as heated production environments.

Application Typical Deployment
Assembly line part presence Flush-mounted at fixture station; ferrous part triggers NO output when seated
Cylinder/actuator position Mounted at stroke end; ferrous flag on rod enters 0-12mm zone at full travel
Conveyor counting and sorting Side-mounted at conveyor edge; each passing ferrous part generates a discrete pulse
Washdown food and beverage lines IP68/IP69K rating used in daily high-pressure spray cleaning environments
Machine tool workpiece detection Spindle-area mounting detects ferrous workpiece presence before cycle start
Guard and door interlock confirmation Detects ferrous target on guard door; output wired to safety relay input channel

Expert Verdict: Is the XS630B1MAL2 the Right Part for Your Project?

The XS630B1MAL2 earns its place as a standard stocking item for retrofit and maintenance teams because it eliminates the procurement complexity that comes with voltage-specific sensor models. A single part number covers 24V DC modern PLC installations and 110V/240V AC legacy relay panels — a genuine operational advantage for multi-facility operations or integrators building equipment for customers with mixed control architectures. The IP68/IP69K dual rating is not a marketing footnote: submersibility to 1 meter for 30 minutes per IEC 60529 combined with high-pressure jet resistance per DIN 40050 means this sensor survives washdown cycles that defeat lower-rated alternatives. The sealed nickel-plated brass body and PPS detection face are built for the kind of production environment where sensors take incidental hits, get sprayed down daily, and are expected to outlast the machine design cycle. For controls engineers standardizing an OsiSense XS inventory across multiple machines, the M30 2-wire NO variant anchors that inventory for the broadest possible application coverage.

Where the XS630B1MAL2 has real limits, the brief is worth stating plainly. The 15mm nominal sensing distance sounds useful at first glance, but the reliable operating zone is 0-12mm — and if your application requires detection beyond 12mm, this sensor will deliver intermittent or no detection without error codes to tell you why. That silent failure is frustrating and expensive. For sensing distances beyond 15mm, the XS7 series covering up to 60mm is the correct family. If your PLC input architecture is built around PNP or NPN logic — which describes the majority of modern 24V DC discrete I/O installations — you need a different OsiSense XS variant, not this model. Applications involving aluminum, copper, or other non-ferrous metals are outside the detection capability of any inductive sensor in this family. And if your application requires analog proportional output, IO-Link diagnostics, or networked communication, the XS630B1MAL2 is fundamentally the wrong product category.

From a procurement standpoint, the XS630B1MAL2 is a well-stocked item at authorized distributors worldwide with no exceptional lead time risk under normal conditions. Buying through a specialist industrial distributor rather than a generic marketplace means you receive a unit that has been handled through verified supply chain channels, with direct access to technical support if integration questions arise mid-project, and expedited replacement logistics if a sensor fails in production.

What Engineers Need to Know Before Ordering the XS630B1MAL2

Community forum discussions for this exact model are limited — most practical feedback on sensors in this class is shared within manufacturing plants and integrator networks rather than public forums. What that means for engineers ordering the XS630B1MAL2 for the first time is that the wrong-part patterns are not widely documented online, which makes pre-order verification more important, not less. The three ordering mistakes that arise most consistently with M30 inductive proximity sensors in this voltage class are worth understanding in detail before you place the order.

The most common and most costly mistake is treating the 15mm nominal sensing distance as the design parameter. Datasheets and product pages list both the nominal sensing distance (15mm) and the actual operating zone (0-12mm) in separate fields, and engineers who design their target approach around the 15mm figure discover the problem in production rather than on the bench. Parts positioned at 12-15mm distance will experience intermittent or no detection, with no PLC error code to identify the cause — the parts simply do not register. The fix requires re-engineering the mounting geometry or target flag position, which is an expensive rework relative to a 30-second gap measurement before installation. Use 0-12mm as your design parameter and target 10mm or less for margin.

The second pre-order verification that saves field rework is output logic confirmation. The XS630B1MAL2 is a 2-wire normally open discrete sensor. Modern 24V DC PLC input cards are frequently wired for PNP or NPN sourcing/sinking logic, and 2-wire AC/DC sensors behave differently in those input circuits than 3-wire transistor output sensors. If your input card datasheet specifies PNP or NPN input type, confirm your wiring architecture supports 2-wire connection before ordering. The switching capacity limit — 5-200mA DC and 5-300mA AC — is the third constraint that catches engineers who intend to drive a relay coil, solenoid, or indicator lamp directly from the output. Those loads frequently draw 50-150mA or more, and exceeding the rated switching capacity causes premature output failure that presents as intermittent switching before complete failure. Size an intermediate relay or solid-state relay for any load that approaches the switching capacity ceiling.

Wiring and Installation Overview for the XS630B1MAL2

  • The XS630B1MAL2 uses a 2-wire pre-attached 2m cable (2 x 0.34mm² conductors); one conductor connects to the supply voltage hot/phase terminal and the other routes through the PLC input terminal to complete the circuit — no separate power and signal conductors as in 3-wire PNP/NPN sensors
  • For DC installations, verify correct polarity before applying power; incorrect polarity will not damage the sensor but the output will not function — confirm against the wiring diagram in the manufacturer datasheet
  • The M30 x 1.5 threaded body installs into a prepared cavity with 52mm of threaded engagement depth; tighten the locking nut to snug plus approximately one-quarter turn — over-tightening the brass body risks thread damage
  • Route the 2m sensor cable at minimum 300mm away from high-voltage motor cables, VFD output conductors, and contactor wiring to prevent EMI coupling that causes intermittent false detections; if bundling is unavoidable, use a dedicated shielded conduit path for the sensor cable
  • After power-up, verify the yellow LED is off with no metal present, then introduce a ferrous steel test piece within the 0-12mm zone and confirm the LED illuminates and the PLC input bit changes state — this two-state LED check confirms correct installation before the machine goes into service

Wrong-Part Prevention Checklist — Verify Before You Order

Use this checklist verbatim before finalizing any order for the XS630B1MAL2. Each item addresses a confirmed ordering or installation error pattern for M30 sensors in this class:

  1. Confirm M30 x 1.5 thread size matches the mounting cavity (most common error: confusing M30 with M18 or M12)
  2. Verify 0-12mm operating zone is adequate (do not assume 15mm nominal is usable in all conditions)
  3. Check supply voltage is within 24-240V AC/DC range (verify PLC output and power supply compatibility)
  4. Confirm that normally open (NO) discrete output matches the PLC input wiring logic
  5. Check 2m cable length is sufficient for routing; confirm cable must not exceed length without extension
  6. Verify IP68/IP69K rating is required for your environment (e.g., washdown, moisture, dust)
  7. Confirm flush-mount (shielded) design is needed (non-flush variants available in OsiSense XS family)
  8. Check that 2-wire configuration (not 3-wire PNP/NPN) is compatible with your input card

If any item on this checklist raises a flag, contact the LeadTime.ca team before ordering — confirming the correct variant now prevents field rework and downtime later. You can also review the full XS630B1MAL2 product page for datasheet access and current availability.

Frequently Asked Questions

Why does my XS630B1MAL2 detect reliably at 8mm but miss detections at 13mm?

The 15mm nominal sensing distance is measured under ideal laboratory conditions. The actual reliable operating zone is 0-12mm. Objects positioned at 12-15mm from the sensor face fall in a zone where detection is inconsistent — geometry variation, material surface condition, and ambient temperature all affect whether the sensor fires at that distance. Redesign your target approach to stay within 10mm for reliable production operation. If your application genuinely requires detection beyond 12mm, the XS7 series covers up to 60mm.

Can I connect a solenoid coil or relay coil directly to the XS630B1MAL2 output?

Only if the coil current draw is verified to fall within 5-200mA DC or 5-300mA AC. Many relay coils and solenoids draw 50-150mA or more, which can approach or exceed these limits. Calculate the actual load current before wiring. If the load is near or above the rated switching capacity, install an intermediate relay or solid-state relay rated for the coil current, and use the XS630B1MAL2 output to drive only the intermediate device's low-current control input.

Is the XS630B1MAL2 compatible with stainless steel targets?

Stainless steel is a ferrous alloy and is detectable by inductive sensors, but the effective sensing distance is reduced compared to mild steel (Fe) because of stainless steel's lower magnetic permeability. The 15mm nominal and 0-12mm operating zone figures are referenced to standard Fe targets. With stainless steel, expect a reduction in reliable sensing distance — verify actual detection distance with your specific grade of stainless using a test piece before finalizing the installation geometry.

How do I distinguish between a wiring fault and a failed sensor using the yellow LED?

A healthy sensor with correct wiring shows the yellow LED off when no metal is present and on when ferrous metal enters the 0-12mm zone. If the LED is permanently on with no metal present, suspect a wiring fault (short circuit or incorrect polarity in DC). If the LED never illuminates even with metal at 5mm distance, check supply voltage at the terminal with a multimeter and confirm polarity for DC installations. If voltage is confirmed correct and the LED still does not respond, the sensor output stage has likely failed and replacement is required.

Does the 2-wire AC/DC design create any limitations when connecting to a modern 24V DC PLC input card?

Two-wire sensors have a small residual leakage current even in the open (off) state — typically a few milliamps — which is inherent to the 2-wire operating principle. Some high-impedance PLC input cards may interpret this leakage current as a logic-high signal, causing false input reads. Check your PLC input card's minimum off-state current threshold against the sensor's leakage current specification in the manufacturer datasheet. If leakage current exceeds the input card's off-state threshold, a bleed resistor wired in parallel with the input terminal resolves the issue. Three-wire PNP/NPN sensors do not exhibit this behavior and are generally preferred for new 24V DC designs.

What is the actual switching frequency limit and does it matter for conveyor counting at typical production speeds?

The XS630B1MAL2 switches at up to 500Hz in DC mode and up to 25Hz in AC mode. For conveyor counting, the relevant limit is DC operation at 500Hz. At 500Hz, the sensor can register 500 discrete object passages per second. For most assembly and packaging conveyors operating at practical part-spacing and line-speed combinations, 500Hz DC provides ample margin. AC mode at 25Hz is the binding constraint if you are operating on an AC supply — verify this ceiling against your conveyor speed and part spacing before committing to AC operation for high-speed counting applications.
