Schneider Electric ZCKJ4045 Limit Switch Rotary Head

Description:

The Telemecanique ZCKJ4045 Limit Switch Body with Spring Return Rotary Head is used for end-of-travel detection and position sensing in industrial automation and machine control systems. Commonly installed in conveyor systems, packaging machinery, assembly equipment, material handling systems, and automated production lines requiring bidirectional rotary actuation. Maintenance teams and system integrators use this part for repair, retrofit, expansion, and replacement of modular XC Standard limit switch assemblies.

Applications:

The Telemecanique ZCKJ4045 combines a fixed metal switch body with an integrated spring-return rotary head, making it suitable for detecting the position of moving machine components from either the left or right direction. It is widely used in industrial machinery, production equipment, packaging lines, conveyors, and material handling applications where reliable snap-action switching and dual changeover contacts are required.
