ORDER NO. 119106
Non-contact safety switch CET-AP-…, with plug connector RC18 and escape release
- Read head with guard locking and integrated evaluation electronics
- Locking force up to 6,500 N
- Short circuit monitoring
- 2 safety outputs (semiconductor outputs)
- Category 4 / PL e according to EN ISO 13849-1
- Plug connector M23 (RC18)
- Unicode
- Door monitoring output
- Indication of the door position by LED
- Teach-in input
- Escape release, 105 mm long
- 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). The output OUT D also remains set when guard locking is active. |

| DIA LED | Diagnostics LED |
| LED 1 rd | illuminates when the solenoid is energized |
| LED 2 gn | illuminates when the door is closed |

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.
Escape release
This is used for manual release of guard locking from the danger zone without tools.
