Ismertetés
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:

Typical actuating ranges
Attention:
The actuating range may vary depending on the substrate material and installation situation.
(Only in combination with actuator CES-A-BBA, CES-A-BCA)

Typical actuating range
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.
(Only in combination with actuator CES-A-BPA)

Typical actuating range
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.
