This safety interlock switch from Schmersal lets you securely lock your machine guards during dangerous processes. The unit's power-to-unlock functionality is vital for machinery where a hazard remains for some time after power-down, such as circular saws. It also means the guard won't be unlocked in the event of a power failure. Thanks to its long service life and high holding force of 1000 Newtons, this is a reliable option for safeguarding your workplace.

IP is a standardised rating for ingress protection. The two numbers rate the product's protection against the intrusion of particles and water. The first number concerns its protection from dust and means Schmersal's interlock switch is completely dust-tight. The second number rates its protection against liquids and means this unit can be fully submerged in 1 metre of water for 30 minutes.
