CES-AR-CR2-CH-SA-105745 (Order no. 105745)

Description

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.

Multicode evaluation

Every suitable actuator is detected by the switch.

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.

Typical actuating range

(actuator CES-A-BLN... in conjunction with safety switch CES-AR-C.2-... in case of mounting on plastic)

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.

Attention:

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