Limit Switch Lever Arm ZCY45
This Telemecanique Sensors ZCY45 lever arm acts as an adjustable roller actuator for limit switches. It is designed for use with XCMD, XCKD, XCKP and XCKT series devices in machinery and automation setups. The steel arm provides a length range of 2.11 in to 4.00 in with a front-mounted roller position.
Thermals Noise and Power Draw
As a passive mechanical component, this lever arm generates no heat, produces no audible noise and draws no electrical power during operation. Its thermoplastic roller ensures smooth actuation without adding thermal load to the system. Performance depends entirely on the limit switch body it is paired with.
Upgrade and Replacement Context
This arm replaces a worn or damaged actuator on compatible Telemecanique limit switches to restore precise mechanical triggering. The adjustable length allows fine-tuning of the actuation point for specific machine travel requirements. It is not suited for applications needing a different roller diameter, material or arm profile than the 0.63 in thermoplastic roller and 0.08 in steel arm provided.

Questions about this item
How do I install the ZCY45 lever arm and what step is often missed?
Mount the arm onto the compatible XCMD, XCKD, XCKP or XCKT switch shaft, then adjust the 2.11 in to 4.00 in arm length and tighten the set screw; the missed step is forgetting to lock the roller position at the front after length adjustment.
What maintenance or replacement will the ZCY45 lever arm need over time?
The 0.63 in diameter thermoplastic roller and 0.22 in wide roller face wear with repeated actuation; inspect the 0.08 in wide steel arm for bending and replace the roller or full arm when the roller surface flattens or cracks.
What limit appears first on the ZCY45 lever arm during sustained operation?
The 0.63 in thermoplastic roller reaches its wear limit before the steel arm, as continuous contact reduces the 0.22 in roller width and can cause the 0.59 in arm depth to flex if the roller deforms unevenly.
