Description
Safety switch
The device may be operated only in conjunction with the actuator CET-A-....
Important: The actuator must be ordered separately.
Unicode evaluation
Each actuator is highly coded (unicode). The switch detects only taught-in actuators. Additional actuators can be taught-in. Only the last actuator taught-in is detected.
Solenoid operating voltage
- DC 24 V +10%, -15%
Guard locking type
CET4 | Open-circuit current principle – guard locking by solenoid force. Activation of the guard locking by applying voltage to the guard locking solenoid. The door position is also monitored. The door monitoring output OUT D is set to HIGH as soon as the actuator is above the extended plunger (state: door closed, guard locking not active). The output OUT D also remains set when guard locking is active. |

Category according to EN ISO 13849-1
Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:
- Category 4 / PL e according to EN ISO 13849-1
Important: To achieve the stated category in accordance with EN ISO 13849-1, both safety outputs (OA and OB) must always be evaluated.
The category is dependent on the installation orientation of the safety switch:

Wire front release (bowden)
The wire front release permits remote unlocking of the guard locking via a pull wire. Flexible routing of the pull wire permits release of the guard locking in inaccessible installation situations.
Important: The wire front release (bowden) is not a safety function.
