The ZCKY43 and ZCKY43C variable length steel roller lever actuators are designed for limit switches, delivering adjustable actuation reach with a durable steel construction. The roller lever provides smooth engagement and reduced wear on the switch mechanism, helping extend actuator life in demanding environments. Key benefits Adjustable length to fit a range of actuation heights and positions, reducing the need for multiple parts. Steel construction offers robust durability in industrial applications and helps withstand frequent actuation. Roller tip provides smooth contact with minimal friction, contributing to precise and repeatable limit switch triggering. Simple integration with standard limit switches that accept roller lever actuators, enabling quick replacement or upgrade. Reliable performance in repetitive cycles and challenging operating conditions due to solid actuator design. Key attributes Functionality: Variable length steel roller lever for limit switches Material: Steel Actuation type: Roller lever Length: Variable (adjustable to fit application requirements) Model variants: ZCKY43 and ZCKY43C (both provide a roller lever actuator for limit switches) Compatibility: Designed to fit standard limit switch assemblies that accept roller lever actuators Performance: Durable actuator suitable for repeated mechanical engagement and reliable switching Specifications at a glance Actuator type: Roller lever Construction: Steel Length: Variable (adjustable) Mounting/compatibility: Fits standard limit switch configurations that use roller lever actuators Variants: ZCKY43, ZCKY43C Applications and use cases Conveyor line endoftravel sensing: Uses the adjustable lever length to trigger the limit switch at the precise position where a product reaches the end of the conveyor, ensuring accurate stops and safe machine operation. Guarding and safety interlocks: Acts as the actuator for safety doors or guards, with an adjustable reach to accommodate different gate geometry and actuation points. Packaging and automation equipment: Enables precise limit switch triggering on machines with changing tooling or workpiece heights, allowing quick adaptation without replacing the actuator. Notes Verify compatibility with the target limit switch model and mounting pattern before installation. Use the adjustable length feature to set the actuation point accurately for your specific application to avoid false triggers or missed activations.
