A non-contact safety switch allows the simultaneous monitoring of several safety guards and up to 20 devices can be included in one switch chain.
Euchner's CES-AR-C non-contact safety switch used in series allows the simultaneous monitoring of several safety guards and up to 20 devices can be included in one switch chain, said the company.
Euchner said that the CES-AR-C is particularly suitable for systems in which a large number of safety guards need to be monitored.
It can also be used as a very compact individual switch.
The small 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, for example, to a safety relay or a safe PLC.
The CES-AR-C has two safety outputs and pulsed signals for integrated short circuit monitoring.
Two LEDs indicate the system status and facilitate diagnosis.
The switch can be used for applications with the highest safety requirements up to safety category 4 in accordance with EN 954-1.
Like all non-contact safety switches in the CES series, Euchner told manufacturingtalk.com that the CES-AR-C is also designed on the basis of proven transponder technology.
It offers the following.
* High protection against tampering.
* A large operating distance.
* Resistance to dirt and vibration.
The housing offers IP67 degree of protection and is therefore suitable for operation under severe conditions.
