Telemecanique XCKM115 Osiswitch Classic Compact Limit Switch, Snap Action, 2-Pole NC+NO — Specifications, Wiring Overview & Buying Guide

When a plant technician or controls engineer is searching for the Telemecanique XCKM115, the decision is almost always already half-made: they have a model number in hand, machinery waiting, and a control circuit to protect. What they need now is confirmation — the right voltage, the right actuator type, and a distributor with stock. The XCKM115 is an Osiswitch Classic compact limit switch from Telemecanique (Schneider Electric), combining a 2-pole snap-action NC+NO contact configuration with a roller lever actuator rated at 240V AC, housed in a metal body measuring 64mm wide by 119mm tall. It separates into two modular components — the ZCKM1 body and the ZCKD15 head — which means a failed sensor head can be field-replaced without pulling the entire unit from the machine.

Who Should Buy the XCKM115 — and Who Shouldn't

The XCKM115 is the right choice when all of the following apply to your application:

  • Your control circuit operates at 240V AC — not 12V DC, 24V DC, 120V AC, or 480V AC
  • Your machinery uses a rotational cam profile with approximately 30° of mechanical travel to actuate the switch
  • You require both an NC contact (for safety or monitoring signal) and an NO contact (for trigger or action signal) in a single device
  • Your machine frame accommodates a 64mm wide by 119mm tall housing with cable entry or rotary head mounting
  • You value field-repairable modular construction — the ZCKD15 head separates from the ZCKM1 body for component-level replacement

If your cabinet runs 24V DC logic, your machinery uses a vertical plunger actuator instead of a rotating cam, or your footprint cannot accommodate the 64 x 119mm housing, this model is not the right fit. Review the Osiswitch Classic product family for plunger-type or miniature-profile alternatives before placing an order.

What the XCKM115 Does in Your Machine

The Telemecanique XCKM115 functions as a binary position sensor — it converts physical mechanical motion into an electrical signal that a PLC, relay, or control circuit can act on. Mounted on a machine frame or moving carriage, the roller lever is actuated by a rotating cam as the carriage or mechanism travels through its stroke. The snap-action mechanism ensures instantaneous contact switching, with no bouncing or gradual transition: the NC contact opens and the NO contact closes at the moment the cam reaches the actuation point within the 30° travel range.

The 2-pole NC+NO configuration is the reason this model is frequently specified for both safety and control functions within the same installation. The NC contact is typically wired into a safety or monitoring circuit — where a loss of signal (open contact) flags a fault condition — while the NO contact drives a control action such as triggering a relay, incrementing a counter, or enabling a downstream actuator. Both functions are served by a single device, eliminating the need for a second switch at the same detection point.

The modular construction is a practical operational advantage backed by official Schneider Electric documentation. Because the ZCKM1 body and ZCKD15 head are separable, maintenance teams can stock replacement heads and perform a component-level swap in minutes — without removing the body from the machine frame, re-drilling mounting holes, or recalibrating cam alignment. This is a meaningful distinction from non-modular competitors in the same compact class.

Where the XCKM115 Sits in a Typical Control System

The XCKM115 occupies the field device layer of a machine control architecture — between the mechanical motion of the machine and the logic layer that interprets position signals. Here is where it sits in a typical deployment chain:

  • Control power supply (240V AC) feeds the limit switch circuit and the PLC input module
  • PLC or relay logic controller receives discrete input signals from the XCKM115 NC and NO terminals
  • XCKM115 body (ZCKM1) is bolted to machine frame; head (ZCKD15) with roller lever faces the cam on the moving carriage
  • Moving carriage or cam follower travels through 30° mechanical arc, actuating the roller lever and triggering snap-action contact change
  • Downstream devices — solenoids, motor starters, alarm relays, or counter inputs — respond to the PLC output logic driven by the limit switch signal

Industries and Applications Where the XCKM115 Is Specified

In automated assembly and material handling environments, the XCKM115 is commonly used to detect pallet or carriage position on conveyor systems and linear motion stages. The roller lever and cam-actuated design suits any application where the moving element passes a fixed point along a defined stroke path.

Machinery OEMs building machine tools, injection molding equipment, or packaging lines frequently specify the XCKM115 for end-of-stroke safety stops — the NC contact provides a fail-safe signal that opens when the switch is actuated, triggering an emergency stop if the carriage overtravel is detected. The same configuration is used to confirm guard closure on production equipment, where the switch signals whether a clamping jaw or actuated access panel has reached its closed position.

In printing, textile, and woodworking machinery, where tooling presence and part positioning must be confirmed before a cycle initiates, the XCKM115 NO contact provides the trigger input to PLC logic. The 64 x 119mm housing fits most standard machine frame mounting pockets without custom fabrication.

Application Typical Deployment
Conveyor pallet detection XCKM115 body mounted on conveyor frame; roller lever actuated by pallet cam as it reaches station
End-of-stroke safety stop NC contact wired to E-stop relay; opens when carriage overtravel is detected at full stroke
Guard and access panel confirmation NC contact confirms panel closed (signal present = safe); loss of signal triggers interlock
Tool and part presence sensing NO contact triggers cycle-start enable signal to PLC when tool or part depresses cam actuator
Clamping jaw position monitoring Both NC and NO contacts used — NC monitors clamp closed, NO triggers downstream process step
Injection molding / machine tool cycle confirmation Roller lever triggered by mold or spindle carriage at home position; NO contact signals PLC ready state

Expert Verdict: Is the XCKM115 the Right Limit Switch for Your Build?

The Telemecanique XCKM115 earns its position as a standard-specification compact limit switch for a specific and well-defined buyer profile: plant technicians replacing worn-out units on existing machinery running 240V AC control circuits, machinery OEMs specifying proven components for new North American builds, and controls integrators who need a field-repairable snap-action switch in a 64 x 119mm metal housing. The modular ZCKM1 body and ZCKD15 head architecture is the feature that separates this unit from non-modular competitors — a failed head is a 3-minute field swap, not a full unit removal, re-mounting, and cam realignment. The dual-contact NC+NO configuration delivers both safety-circuit and control-circuit capability in a single device, which is the other reason this model gets re-ordered consistently on the same machinery platforms.

The XCKM115 has real limits that honest procurement requires acknowledging. If your facility runs 12V DC, 24V DC, or 120V AC control logic, this is not your part — the 240V AC rating is a hard constraint, not a design preference. Machinery with vertical plunger actuation profiles cannot use this model regardless of voltage; the roller lever operates on a 30° rotational cam arc and has no vertical travel. Washdown or food-processing environments requiring IP67 or higher protection should verify the specific IP rating of the standard XCKM115 configuration before specifying it into those environments — the compact class standard rating may not meet those requirements. And for installations where the 64 x 119mm footprint cannot be accommodated, miniature-profile submodels within the Osiswitch Classic family are the correct alternative.

On the procurement side, the most important step any buyer can take before placing an order is voltage confirmation — take a photo of the transformer label in your control cabinet or pull the electrical one-line diagram and confirm 240V AC is present. This single check prevents the most common return and reorder scenario in the XCKM115 buying cycle. For lead time, stock of the XCKM115 and the ZCKD15 head as a standalone spare can vary significantly between generic e-commerce channels and specialist industrial distributors. Check current stock and pricing for the XCKM115 at LeadTime.ca — specialist distributor inventory often eliminates the 2–4 week delays that come with sourcing through non-specialist channels, and the team can verify voltage and mounting compatibility before the order ships.

What Engineers Need to Know Before Ordering the XCKM115

Because community discussion on the XCKM115 specifically is sparse across the major industrial automation forums, the most reliable source of pre-order guidance is the product's own technical documentation combined with the ordering pattern knowledge that specialist distributors accumulate over repeated sales cycles. What follows reflects the recurring ordering challenges and technical clarification points that matter most when specifying this part.

The single most consequential specification to verify is rated voltage. The XCKM115 is rated at 240V AC, and this rating applies to the control circuit — not the machinery power supply. In facilities where a 480V AC main feeds the machinery but a 240V AC or 120V AC step-down transformer supplies the control cabinet, the technician must trace the actual control circuit voltage, not assume it matches the main line. The wrong voltage selection is not a minor incompatibility: it creates a safety hazard, can damage the switch contacts on first actuation under load, and results in a complete order failure that delays production by however long the correct replacement takes to arrive.

The second area where orders go wrong is actuator type confusion within the Osiswitch Classic product family. The XCKM115 uses a roller lever actuated by a rotating cam through 30° of mechanical travel. It does not move vertically. If your machinery has a vertical push rod or a plunger-driven mechanism, the XCKM115 will not function correctly in that installation regardless of how closely the catalog number resembles a plunger-type model. Physically verify the motion profile of your machinery's actuating mechanism before ordering, and cross-reference the head type code (ZCKD15 is the roller lever head) against the motion profile in your equipment documentation. LeadTime.ca's technical team can assist with this verification before the order is placed — which is exactly the kind of support a specialist distributor provides that a generic e-commerce channel cannot.

Wiring and Installation Overview for the XCKM115

The following overview covers the key wiring and installation requirements for the XCKM115. Engineers requiring complete wiring diagrams, terminal torque specifications, or detailed installation procedures should refer to the official Telemecanique / Schneider Electric technical documentation for this model.

  • Identify the three terminals on the XCKM115: Common (C), Normally Closed (NC), and Normally Open (NO). The Common terminal is the shared return for both contact circuits.
  • For a safety or monitoring circuit (fail-safe logic), wire the NC terminal to the PLC digital input; an open contact at the input signals a fault or actuated condition. For a control trigger circuit, wire the NO terminal to the PLC input; contact closure signals the actuated state.
  • Verify the control circuit supply voltage is 240V AC at the terminal before connecting to PLC input modules — if the PLC input card expects 24V DC, an auxiliary relay must be used to convert the 240V AC limit switch signal before it reaches the input module.
  • Mount the ZCKM1 body to the machine frame with sufficient clearance for the 64 x 119mm housing; attach the ZCKD15 roller lever head and align the lever with the machinery cam so that 30° of cam travel produces a positive, audible snap action through the full stroke.
  • Insert the cable through the cable gland, tighten hand-tight first, then a controlled quarter to half turn with a wrench — over-torquing the gland can compromise the IP seal; under-torquing allows cable movement and potential ingress.

Modular Components and Compatible Parts for the XCKM115

The XCKM115 is built on a separable architecture that allows individual components to be stocked and replaced at the field level. The following components are relevant to installation, maintenance, and sparing strategy:

  • ZCKM1 — Limit switch body; the base unit that mounts to the machine frame and houses the contact block. Ordering the body separately allows reuse when only the head has failed.
  • ZCKD15 — Roller lever head; the field-replaceable actuator component that interfaces with the machinery cam. Stocking ZCKD15 heads as spare parts is the recommended maintenance strategy for facilities with multiple XCKM115 installations — a head swap takes minutes and does not require disturbing the wiring or body mounting.

Verify current availability of ZCKM1 and ZCKD15 as standalone components with LeadTime.ca before building a sparing plan — component availability can vary independently of the assembled XCKM115 unit stock.

Wrong-Part Prevention Checklist Before Ordering the XCKM115

Review every item on this checklist against your application before placing an order. A single mismatch on any of these points will result in the wrong part arriving on site.

  1. Verify your control circuit voltage is 240V AC (not 12DC, 24DC, 120V AC, or 480V AC)
  2. Confirm machinery motion is rotational cam (30° travel) activating roller lever, not vertical push
  3. Check mounting clearance: this model is 64mm wide x 119mm tall; measure available space on machine
  4. Verify contact requirement: you need both NC (safety signal) and NO (trigger signal), or just one?
  5. Confirm cable entry or rotary head mounting fits your machine topology and wiring layout
  6. Check if separated components (ZCKM1 body + ZCKD15 head) or pre-assembled unit is in your supply chain
  7. Verify IP rating (degree of protection) matches environment (standard industrial, washdown, or high-temperature)
  8. Confirm response time acceptable for your application (snap action is instantaneous; confirm no delay needed)

If any item on this checklist raises a question you cannot resolve from your equipment documentation, contact the LeadTime.ca team before ordering — it is faster than processing a return and waiting for a replacement to ship.

Frequently Asked Questions

Can the XCKM115 be wired into a 24V DC PLC input module directly?

No. The XCKM115 is rated at 240V AC for its control circuit. A 24V DC PLC input module cannot directly accept a 240V AC switched signal without an intermediate auxiliary relay or signal converter. The relay converts the 240V AC contact closure into a 24V DC signal that the PLC input card can read. Verify your PLC input voltage before wiring.

What is the difference between the ZCKM1 body and the ZCKD15 head, and which one fails first?

The ZCKM1 is the contact body — it houses the snap-action contact block and the wiring terminals. The ZCKD15 is the roller lever head — the mechanical actuator that interfaces with the machinery cam. The head experiences the greatest mechanical wear because it absorbs the impact of the cam on every actuation cycle. In most field failure scenarios, the ZCKD15 head is the component that fails, not the ZCKM1 body. Stocking ZCKD15 heads as consumable spares is the recommended maintenance approach for high-cycle applications.

How do I confirm the XCKM115 has failed rather than a wiring issue?

With power removed from the control circuit, use a multimeter in resistance mode. Test between the Common (C) terminal and the NO terminal — with the lever at rest (not actuated), resistance should be near infinite. Manually press the roller lever through its 30° arc; resistance should drop to near zero at actuation. Test the NC terminal in the same way — it should show near zero at rest and open at actuation. If resistance does not change in either test, the ZCKD15 head has failed internally. If resistance changes correctly but the PLC still does not receive a signal, trace the wiring continuity from the switch terminals to the PLC input card.

Is the XCKM115 a direct replacement for XCK-J series switches?

The XCKM115 (Osiswitch Classic compact series) and the XCK-J series are both Telemecanique limit switches but differ in housing size, mounting geometry, and actuator head compatibility. They are not automatic drop-in replacements for each other. Before substituting one for the other, verify that the mounting hole pattern, cable entry orientation, and actuator travel angle match your machine frame. Consult the official Schneider Electric product comparison documentation or contact LeadTime.ca for a compatibility check.

What happens if the cam over-travels beyond 30° — does the XCKM115 self-reset or does it require replacement?

The snap-action mechanism in the XCKM115 is designed for the rated 30° cam travel range. Consistent over-travel beyond the rated actuation angle accelerates mechanical wear on the ZCKD15 roller lever and can damage the internal contact spring over time. The switch will typically reset when the cam returns to its unactuated position, but repeated over-travel shortens service life significantly. If your machinery geometry produces over-travel, adjust the cam stop or mount position before the switch is installed to keep actuation within the rated range.

Does LeadTime.ca stock the XCKM115 and the ZCKD15 head separately?

Stock levels for both the assembled XCKM115 and the standalone ZCKD15 head vary and should be verified before committing to a delivery schedule. Lead time for this product family is typically in the 1–4 week range from standard distributor channels, but specialist distributors with local inventory can often improve on that significantly.
