Non-contact safety switch CES-A-C5...
- Safety switch with integrated evaluation electronics
- Pulsed signals can be switched
- 2 safety outputs (semiconductor outputs)
- Category 3 / PL e according to EN ISO 13849-1
- Unicode

Description
Approach direction
Can be adjusted in 90° steps
Unicode evaluation
Each actuator is highly coded (unicode). The switch detects only taught-in actuators. Additional actuators can be taught-in.
Category according to EN ISO 13849-1
Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:
- Category 3 / PL e according to EN ISO 13849-1
LED indicator
STATE | Status LED |
OUT/ERROR | Safety outputs status / diagnostics LED (combined) |
Additional connection
OUT | Monitoring output (semiconductor) |
Typical actuating ranges
Attention:
The actuating range may vary depending on the substrate material and installation situation.
Typical actuating range
(Only in combination with actuator CES-A-BBA, CES-A-BCA)

For a side approach direction for the actuator and safety switch, a minimum distance of s = 4 mm must be maintained so that the actuating range of the side lobes is not entered.
Typical actuating range
(Only in combination with actuator CES-A-BPA)

For a side approach direction for the actuator and safety switch, a minimum distance of s = 6 mm must be maintained so that the actuating range of the side lobes is not entered.
