Telemecanique Sensors ZCKY071 Limit Switch Operating Key

Product Description

The TELEMECANIQUE SENSORS ZCKY071 is a limit switch operating key designed as a direct replacement accessory for compatible limit switch assemblies. This lever-style key attaches to the switch actuator mechanism and converts mechanical contact from a moving machine member into a switching action. At 3.5 inches in overall length, it provides the reach needed for standard actuator clearances in industrial control applications. Electricians and automation technicians install this part as a service replacement when an existing operating lever is worn, damaged, or missing. Its compact profile fits within typical panel and machine guard envelopes.

This operating key is intended for use with limit switches in industrial machinery, automated production equipment, and motion-control applications. It functions as the interface between the moving mechanical element and the switch body, triggering position sensing or end-of-travel cutoff signals. Typical installations include conveyor systems, machine tool guards, press equipment, and similar automated machinery where limit switch actuation is required. The part is packaged individually and suited for maintenance and repair scenarios.

Key Features

• Operating lever style switch accessory for limit switch assemblies
• Overall length of 3.5 inches for standard actuator reach
• Low-profile form factor fits within machine guard and panel envelopes
• Single-unit packaging supports one-at-a-time maintenance replacement
• Lightweight construction at 0.05 pounds minimizes added load on actuator mechanism

Compatibility

Designed as an OEM-style replacement operating key for use with compatible TELEMECANIQUE SENSORS limit switches. Consult the switch manufacturer documentation to confirm fitment with a specific limit switch series before installation.

Installation Notes

Installation should be performed by a qualified electrician or industrial maintenance technician familiar with limit switch assemblies. De-energize and lock out the machine circuit per NFPA 70E and applicable OSHA lockout/tagout procedures before removing or installing any limit switch component. Verify that the key engages the actuator plunger or roller arm fully and that no binding occurs through the full range of mechanical travel before restoring power.
