Non-contact safety switch CET-AR-…, M12
- Safety switch with guard locking and integrated evaluation electronics
- Locking force up to 6,500 N
- Up to 20 switches in series
- Short circuit monitoring
- 2 safety outputs (semiconductor outputs)
- Category 4 / PL e according to EN ISO 13849-1
- With 2 plug connectors M12
- Unicode
- Door monitoring output
- Indication of the door position by LED
- Teach-in input
- Approach direction A (delivery state)
Approach direction
Horizontal
Can be adjusted in 90° steps
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
| CET3 | Closed-circuit current principle, guard locking by spring force. Release 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). OUT output D also remains set when guard locking is active. |

| DIA LED | Diagnostics LED |
| LED 1 rd | freely configurable |
| LED 2 gn | illuminates when door is closed |
Additional connections
| OUT | Monitoring output (semiconductor) |
| OUT D | Door monitoring output (semiconductor) |
| RST | Reset input |
| J | Teach-in input |
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
- The stated safety characteristics apply to any installation orientations of the safety switch.
Important: To achieve the stated category in accordance with EN ISO 13849-1, both safety outputs (OA and OB) must be evaluated.
