The Safety Locking Switch is designed for applications where hazardous conditions persist even after the machine is powered off. It ensures that access to dangerous areas is restricted until safe conditions are met, making it suitable for machines with residual motion, such as pulleys or saw blades.

This model operates with a locked actuator when the solenoid is de-energized. It features mode 1 functionality, where safety outputs remain active when the guard is closed and locked. It complies with ISO 14119 standards for interlocks with guard locking.

This switch is ideal for controlling access to machine guards under specific conditions, enhancing safety in industrial applications where residual hazards exist.
