Non-contact safety switch CES-AR-C01...
- Safety switch with integrated evaluation electronics
- Up to 20 switches in series
- Short circuit monitoring
- 2 safety outputs (semiconductor outputs)
- Category 4/PL e according to EN ISO 13849-1
- Unicode

Description
Approach direction
Can be adjusted in 90° steps
Short circuit monitoring
The switch generates its own clock signal on the output lines OA/OB. Pay attention to this aspect when connecting to control systems and relays.
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.
Category according to EN 13849-1
Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:
- Category 4/PL e according to EN 13849-1
Important: To achieve the stated category in accordance with EN ISO 13849-1, both safety outputs (OA and OB) must be evaluated.
