EuchnerCET4 safety switch

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 door monitoring output. It is based on the open circuit current principle.

By applying voltage at the guard locking solenoid, guard locking is activated. The door monitoring output allows the control system to recognise whether the safety door is closed or not, independently of the guard locking function. This is particularly advantageous in the case of larger installations involving several CET4 safety switches connected in series. Previously, the user could not recognise which door was closed. This can now be conveniently polled via the door monitoring output on the control system and the user does not have to visually inspect each switch.

The CET4 is suitable for operation as a single unit and in a series connection. A start button and a feedback loop can be optionally integrated. The CET-AR switch is characterised by its tampering resistance and the IP67 degree of protection. Robust metal housing permits locking forces up to 6,500 N and external LEDs permit a detailed diagnostic function and the option of individual assignment by the user.
