Schneider Electric XSAV11801 Telemecanique OsiSense M30 inductive proximity sensor for industrial shaft rotation monitoring

Telemecanique OsiSense XS Inductive Proximity Sensor, Rotation Monitoring, M30, Sn 10mm, 6-150 cyc/min, 24-240VAC/DC, Cable 2m — XSAV11801 Specifications, Wiring and Installation Guide

Controls engineers sourcing a rotation monitoring sensor for shaft speed feedback or fault detection need to confirm three things quickly: sensing distance, supply voltage compatibility, and thread size. The Schneider Electric XSAV11801 — a Telemecanique OsiSense XS series cylindrical inductive proximity sensor — answers all three with a 10mm nominal sensing distance, a wide 24-240 VAC/DC supply range, and a standard M30 x 1.5 thread that fits most existing machine mounts without custom fabrication. If you are replacing an existing M30 inductive sensor or specifying a new rotation monitoring point in a ferrous-target application, this is the sensor that eliminates supply voltage variant selection while delivering IP67 protection in a sealed metal enclosure rated for -25 to 70°C.

Who Should Buy the XSAV11801 — and Who Shouldn't

This sensor is the right choice for engineers and procurement specialists who need a discrete 1NC output rotation monitoring sensor with broad voltage flexibility in a standard M30 form factor. It is a strong fit when all of the following apply:

  • Your target object is ferrous metal — iron or steel gear tooth, bolt head, or target wheel mounted on the shaft
  • The physical gap between sensor face and target falls within the 8-15mm operating range, with 10mm nominal
  • Your plant supply voltage is anywhere in the 24-240 VAC or 24-210 VDC range
  • The mounting point accepts an M30 x 1.5 threaded sensor body
  • Your shaft speed stays within 6 to 150 cycles per minute at the sensing point
  • A 2m fixed cable run is adequate, or you can extend with an external cable

If your application requires a longer or shorter sensing distance than 10mm, an analog 4-20mA output instead of a discrete contact, multiple output contacts, or detection of non-ferrous targets such as aluminum or copper, a different model within the OsiSense XS family is the correct specification. Confirm your requirements before ordering.

What the XSAV11801 Actually Does in a Rotation Monitoring System

The XSAV11801 is a fixed cylindrical inductive proximity sensor from the Telemecanique OsiSense XS series, specifically configured for rotation monitoring duty. It does not measure speed as a continuous analog value — it generates a discrete output pulse on each pass of a ferrous metal target. A PLC, VFD, or dedicated monitoring relay counts those pulses over time to calculate shaft speed, confirm rotation is occurring, or detect a stopped-shaft fault condition.

The sensor mounts to a machine frame or enclosure using its M30 x 1.5 threaded body. The ferrous target — a gear tooth, bolt, or custom target wheel — passes the sensor face at close range during normal shaft rotation. Each pass causes the sensor's normally-closed 1NC output contact to switch state. That switching event is the signal. The wide 24-240 VAC/DC supply range means the same physical sensor can be powered from a 24VDC PLC input card or from a 120VAC monitoring relay without changing the part number, which is a real inventory and commissioning advantage in mixed electrical environments.

The IP67 sealed metal enclosure keeps this sensor reliable in environments with coolant spray, grease, dust, and temperature swings between -25°C and 70°C. These are the exact conditions that fail optical or capacitive sensors in machine tool and heavy industrial service.

Typical System Architecture for Shaft Speed and Rotation Fault Detection

The XSAV11801 sits between the rotating mechanical element and the control or monitoring device that needs to know shaft state. Understanding its position in the signal chain helps confirm correct mounting and wiring before installation.

  • Rotating shaft carries a ferrous target (gear tooth, bolt head, or mounted target disc) that passes the sensor face once per revolution or at a defined pulse-per-revolution ratio
  • XSAV11801 mounted on fixed machine frame or bracket, M30 x 1.5 thread, sensor face aligned to target at 8-15mm gap
  • 2m fixed cable from sensor body routes to terminal block or direct wire connection at control panel
  • Discrete 1NC output signal connects to PLC digital input card, VFD speed feedback terminal, or dedicated rotation monitoring relay
  • Control device interprets pulse frequency to calculate RPM, confirm shaft running status, or trigger a fault output on underspeed or stopped-shaft condition

Industries and Machine Types Where This Sensor Is Specified

Rotation monitoring with a discrete inductive sensor is a fundamental requirement across manufacturing, processing, and utilities. The XSAV11801 is specified wherever a ferrous target can be mounted to a rotating element and the control system needs a reliable run/stop confirmation or speed feedback signal.

In conveyor and material handling systems, this sensor confirms that drive shafts and rollers are turning at expected speed. A stopped-shaft signal from the sensor triggers a jam alarm before product damage or mechanical failure occurs. The IP67 rating handles the wash-down and debris exposure common in food processing and packaging lines.

In pump and fan applications, the sensor provides overspeed and underspeed protection. A gear tooth or bolt on the pump shaft passes the sensor on each revolution. The monitoring relay calculates RPM from the pulse rate and trips an alarm or shutdown if speed drifts outside the setpoint band.

In machine tool and industrial equipment service, the sensor monitors spindle rotation confirmation, indexer position, or gear change verification. The metal sealed body and operating temperature range down to -25°C make it usable in outdoor and unheated equipment enclosures.

Application Typical Deployment
Conveyor drive shaft monitoring Sensor mounted to frame, bolt head on shaft as target, 1NC output to PLC jam detection input
Pump overspeed/underspeed protection Sensor on pump housing, gear tooth target, output to monitoring relay with speed setpoints
Fan and blower rotation confirmation Sensor on motor or fan housing, target on shaft coupling, output to VFD run confirmation input
Machine tool spindle feedback Sensor on headstock or gearbox, target wheel on spindle, pulse signal to CNC or PLC
Industrial mixer shaft monitoring Sensor on mixer frame, ferrous target on agitator shaft, output to process control system

Expert Verdict: Is the XSAV11801 the Right Sensor for Your Application?

The XSAV11801 earns its place on the BOM for maintenance engineers and OEM machine builders who need a no-compromise rotation monitoring sensor in a standard M30 form factor. The combination of 24-240 VAC/DC compatibility and an IP67 sealed metal body means this sensor works equally well powered from a PLC input card at 24VDC or from a legacy 120VAC monitoring relay — without stocking two different catalog numbers. The -25 to 70°C operating range and proven OsiSense XS build quality make it a direct fit for outdoor equipment, unheated enclosures, and wash-down machine environments where optical alternatives fail prematurely. The 10mm nominal sensing distance with an 8-15mm working range gives enough mounting tolerance for real-world shaft runout and bracket variation.

The honest limits are these: the 6-150 cycles per minute frequency response is adequate for most conveyor, pump, and fan applications, but if your shaft delivers target pulses at higher frequency — for example, a multi-tooth target wheel on a high-speed spindle — the response ceiling may be insufficient and you will need a higher-frequency variant. The 1NC discrete output is correct for run/stop monitoring and pulse counting, but it is not a substitute for an encoder or analog speed sensor if your application requires continuous velocity feedback with fine resolution. The 2m fixed cable is a practical constraint: this is not a connector-body version, so plan your routing and add extension cable if the control panel is further than 2m from the mounting point.

From a procurement standpoint, the XSAV11801 is a well-established catalog part in the Telemecanique OsiSense XS series with predictable availability through specialist distributors. Buying through a distributor with genuine sourcing depth and global shipping capability matters when a sensor failure causes production downtime — lead time visibility before you commit to a build schedule is worth confirming.

What Engineers Need to Know Before Ordering the XSAV11801

Community discussion around this specific catalog number is limited — the XSAV11801 is a specialist rotation monitoring sensor rather than a general-purpose proximity switch, and engineers specifying it tend to work from manufacturer documentation and distributor support rather than open forum threads. That makes pre-order verification more important, not less. The most common specification mistakes in this product category are predictable and avoidable if you check the right parameters before placing an order.

The single most frequent wrong-part scenario in inductive sensor procurement is target material mismatch. Inductive sensors detect ferrous metal only. If your target wheel, gear, or trigger bolt is aluminum, brass, copper, or plastic, the XSAV11801 will not detect it — regardless of gap distance or supply voltage. Confirm your target material before ordering. The second most common issue is sensing gap miscalculation: engineers measure the nominal shaft position but do not account for runout, thermal expansion, or bracket flex under load. The XSAV11801 has an 8-15mm operating range around the 10mm nominal. Verify the actual gap at closest approach under operating conditions, not just at rest.

Cable length is a frequently overlooked constraint in replacement orders. The 2m fixed cable on the XSAV11801 is not field-replaceable. If the original installation used a connector-body sensor with a longer cable, you cannot simply drop in this model without adding an extension. Similarly, the 6-150 cycles per minute frequency response defines the maximum useful shaft speed at the sensing point — if your target geometry places multiple teeth past the sensor per revolution, calculate effective pulse frequency before confirming this model is adequate. Buyers who work with the LeadTime.ca team before ordering rather than after delivery avoid these delays.

Wiring and Installation Overview

  • The XSAV11801 has a 2m fixed cable — identify the supply voltage wires and the 1NC output wires before connecting; refer to the Schneider Electric / Telemecanique product datasheet for exact wire color assignments and terminal identification
  • Supply voltage can be 24-240 VAC (50/60 Hz) or 24-210 VDC — confirm your panel supply before wiring; the wide range does not require any internal switching or jumper configuration
  • The 1NC output contact switches between 5mA minimum and 200mA DC maximum (or 350mA AC maximum) — verify that the connected PLC input or monitoring relay load current falls within this range
  • Mount the M30 x 1.5 threaded body securely to a fixed machine frame bracket; set the face-to-target gap to 10mm nominal, confirmed within the 8-15mm operating range with the shaft turning under load
  • IP67 sealing requires that cable entry and any junction connections be made with appropriate IP-rated fittings; the sensor body itself is sealed but the cable termination point must be protected independently

Wrong-Part Prevention Checklist

Before placing your order for the XSAV11801, verify each of the following against your actual installation requirements:

  1. Confirm target object is ferrous metal (iron/steel). Inductive sensors do not detect aluminum, copper, plastic, or non-ferrous metals.
  2. Verify sensing distance requirement matches 10mm nominal. Measure actual gap between sensor face and target at closest approach. Must be within 8-15mm range.
  3. Confirm supply voltage compatibility: sensor accepts 24-240 VAC or 24-210 VDC. Check plant main voltage.
  4. Check M30 x 1.5 thread matches sensor mounting hole. If mounting point has different thread, sensor will not fit.
  5. Verify IP67 rating is adequate for environment. IP67 means submersible to 1m depth for short periods but not rated for continuous immersion.
  6. Confirm switching capacity of load. Sensor can switch 5-200mA DC or 5-350mA AC. If load draws >200mA DC, sensor may fail.
  7. Check cable length requirement. Model includes 2m fixed cable (not replaceable). If installation requires 5m run, must add external extension.
  8. Verify frequency response adequate for shaft speed. Sensor supports 6-150 cycles/min. Check if upper limit sufficient for actual RPM range.

Frequently Asked Questions

Can the XSAV11801 detect aluminum or stainless steel targets?

No. The XSAV11801 is an inductive proximity sensor that responds to ferrous metal — iron and steel — only. Aluminum, copper, brass, and non-ferrous metals will not trigger a detection event. Plastic and non-metallic targets will also not be detected. If your target material is non-ferrous, you will need a different sensing technology.

What happens if shaft speed exceeds 150 cycles per minute at the sensor?

The XSAV11801 has a rated frequency response of 6 to 150 cycles per minute. If pulse frequency at the sensor exceeds 150 cycles per minute — whether from high shaft RPM or from a multi-tooth target wheel — the sensor output may not reliably track each target pass and you will lose counting accuracy or miss events. For higher-frequency applications, select a variant from the OsiSense XS series with a higher rated response frequency.

Is this a direct replacement for an existing M30 inductive sensor with a connector body?

The M30 x 1.5 thread and 10mm sensing distance may match an existing installation, but the XSAV11801 has a 2m fixed cable, not a connector body. If the sensor being replaced used a detachable connector and a separate cable, this model is not a direct drop-in without modifying the cable arrangement. Confirm body style and cable termination type before substituting.

Can I use the XSAV11801 on both an AC and a DC supply in the same plant without stocking two different sensors?

Yes — this is one of the main reasons this model is specified. The 24-240 VAC/DC supply range means a single catalog number covers both 24VDC PLC-powered circuits and 120VAC or 240VAC monitoring relay circuits without any internal configuration change. This reduces procurement complexity and simplifies spare parts inventory.

What does the 1NC output mean for my PLC wiring?

The 1NC (normally closed) output means the output contact is closed — conducting — when no target is present. When a ferrous target passes the sensor face, the contact opens, interrupting the circuit. Your PLC input will see a signal state change on each target pass. Verify that your PLC input card or monitoring device is configured to interpret a normally-closed input logic correctly, as this is the inverse of a normally-open sensor output.

Does IP67 mean this sensor can be permanently submerged in coolant or wash-down water?

No. IP67 means the sensor is protected against short-duration submersion to 1m depth, not continuous immersion. For applications with sustained liquid exposure or high-pressure wash-down, verify whether IP67 is sufficient for the specific cleaning and exposure conditions in your facility before installing.
