IP67 degree of protection
The CET4 safety switch from Euchner combines the non-contact transponder technology from the CES systems with a monitored guard locking function, an integral evaluation electronics as well as the door monitoring output. The guard looking is based on the open-circuit current principle. By applying voltage at the guard locking solenoid the guard locking is activated. The door monitoring output allows the control system to recognize whether the safety door is closed or not, independently of the guard locking function.
