Zinc lever arm with front thermoplastic roller, 1.61 in long, 0.88 in roller diameter

Telemecanique Sensors

Telemecanique Sensors ZCKY11 limit switch lever arm 1.61 in

SKU CH-J74N-8K7PX

A 1.61 in zinc lever arm with a 0.88 in thermoplastic roller fits XCKJ, XCKL and XCKM limit switches

  • Standard roller actuator suits XCKJ, XCKL and XCKM switches
  • 61 in arm length gives precise trip-point positioning
  • Front-mounted 0.88 in thermoplastic roller reduces wear
  • Zinc arm with 0.17 in width fits tight mounting spaces
  • 5 in arm depth adds mechanical rigidity

Lever arm for limit switches

The Telemecanique Sensors ZCKY11 is a replacement lever arm designed for XCKJ, XCKL and XCKM limit switch bodies. It provides the mechanical actuation interface for industrial machinery and automation equipment.

Standard roller actuator changes contact operation

The front-mounted thermoplastic roller reduces friction and wear during repetitive actuation cycles. Its 0.88 in diameter and 0.2 in width suit standard cam profiles, while the zinc arm resists corrosion in harsh environments.

1.61 in arm length sets the actuation reach

This dimension determines the trip point relative to the switch mounting face. The 0.17 in arm width and 0.5 in depth fit the designated switch housings. Buyers needing a different roller position, roller material or arm length cannot use this part.

Questions about this item

Will the zinc arm or thermoplastic roller need replacement first under repeated actuation?

The thermoplastic roller typically wears before the zinc arm because it absorbs impact at each cycle.

What mechanical limit is reached first during continuous operation?

The 1.61 in arm length sets the maximum travel before the roller over-travels the cam profile.

How much heat does the lever arm generate when the switch runs all day?

The passive arm produces no measurable heat; only the switch body dissipates power during actuation.
