Non-contact
November 1st 2007 The new CES-AR-C non-contact safety switch from Euchner makes it possible to monitor several safety guards at once. Up to 20 devices can be included in one switch chain. The device can also be used as a compact individual switch. The housing accommodates a read head and an evaluation unit. When used in a switch chain, the individual switches are connected with each other by means of plug connectors. The end of the chain is connected to a safety relay or a safe PLC, for example. The CES-AR-C has two safety outputs and pulsed signals for integrated short circuit monitoring. Two LEDs indicate system status and facilitate diagnosis. The switch provides Category 4 safety in accordance with EN 954-1. The switch is designed on the basis of proven transponder technology. This means protection against tampering, a large operating distance and resistance to dirt and vibration. The housing offers IP67 protection. More articles from Euchner (UK) Limited: |
