- Category 4/PL e according to EN ISO 13849-1
LED indicator
STATE | Status LED |
OUT/ERROR | Safety output status/diagnostics LED (combined) |
Additional connection
OUT | Monitoring output (semiconductor) |
Attention:
The actuating range may vary depending on the substrate material and installation situation.
Typical actuating range
(only in combination with actuators 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.
