The safety interlock switch is designed to prevent movable safety guards from being opened until hazardous conditions are resolved, working in conjunction with a machine's control system. It features a thermoplastic enclosure with double insulation, ensuring durability and electrical safety.
The switch includes one cable entry (M20 x 1.5) and a screw connection for secure installation. It also has a manual release mechanism. Its compact design accommodates tight spaces, and it offers high holding force with protection against incorrect locking. This makes it suitable for environments where secure and reliable locking is crucial. The interlock is built for long-term use, providing consistent performance over time.
