Non-contact safety switch CES-AR-C01…

  • Safety switch with integrated evaluation electronics
  • Up to 20 switches in series
  • Short circuit monitoring
  • 2 safety outputs (semiconductor outputs)
  • Category 4 / PL e according to EN ISO 13849-1
  • Unicode

Approach direction

Can be adjusted in 90° steps

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.

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 in accordance with EN ISO 13849-1, both safety outputs (OA and OB) must be evaluated.

Typical actuating range

With actuators CES-A-BBA and CES-A-BCA

<p>With actuators CES-A-BBA and CES-A-BCA</p>

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.With actuator CES-A-BPAFor 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.
