Installation position

Permissible installation position


The actuating range may vary depending on the substrate material and installation situation.

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

<p>Typical actuating range<br>(Only in combination with actuator CES-A-BBN)</p>

For a side approach direction for the actuator and safety switch, a minimum distance of s = 10 mm must be maintained so that the actuating range of the side lobes is not entered.

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 according to EN ISO 13849-1, both safety outputs (FO1A and FO1B) must be evaluated.
