Euchner’s transponder coded safety switches for ATEX applications

Treotham announces that the CES-C04-AP/AR transponder coded safety
switches from Euchner can now be used in potentially explosive atmospheres in
zone 2 (gases) and zone 22 (dusts). Existing ATEX directives and corresponding
standards place special requirements on the equipment from which an ignition
hazard can start.

Placed inside a specially developed plastic housing guard to effectively
protect the safety switch against the effects of possible impacts, the CES-C04-AP/AR
meets the requirements of the ATEX directive.

For explosion protection, the compact safety switches are available as
interlocking devices without guard locking or with monitored guard locking for
the safety of personnel.

The CES-C04-AP/AR transponder coded safety switches also feature status
LED indications readily visible through windows in the housing guard. Installed
CES-C04 devices in the field can be retrofitted at any time.
