Manufacturer Part # : Transponder-coded-safety-switches-according-to-ATEX-directive
Manufacturer : EUCHNER
Description : Description In potentially explosive atmospheres, according to the ATEX directive and the corresponding standards, special requirements are placed on the equipment used from which an ignition hazard can emanate. Transponder-coded safety switches are ATEX devices according to categories 3D/3G and can be used in hazardous zones 2 and 22 (gases or dusts). For explosion protection, safety switches are available as interlocking devices without guard locking or with monitored guard locking. The transponder-coded actuators have unique coding. The actuators must be taught-in by the integrated evaluation electronics for unicode version safety switches. It is only possible to switch the safety outputs using the actuator already taught-in. As such the unicode principle provides a high level of protection against tampering on bypassing safety guards. Features Suitable for usage in zone 2 and 22 (gases and dusts) Compact design Integrated evaluation electronics With door monitoring signal 2 safe semiconductor outputs Series connection of several switches possible Maximum safety level PL e, category 4
