The smallest transponder-coded safety switch CES-C04 from EUCHNER is now available with an AR interface for series connection of up to 20 devices.
Connecting several safety switches in series has proven to be an economical solution, particularly for larger machines and installations requiring protection of several safety doors. In addition to the safety switch CES-AR-C04, all other EUCHNER devices with an AR interface can be connected in series.
The CET4 safety switch from Euchner combines the non-contact transponder technology from the CES systems with a monitored guard locking function, an integral evaluation electronics as well as the door monitoring output. The guard looking is based on the open-circuit current principle. By applying voltage at the guard locking solenoid the guard locking is activated. The door monitoring output allows the control system to recognize whether the safety door is closed or not, independently of the guard locking function.
