The built-in proximity switch is indicated on the type
plate as product coding and wiring diagram.
For use in potentially explosive atmospheres, the devices must be connected to certified
intrinsically safe circuits.
For non-electrical part of device the requirements of the applicable standards EN ISO 80079-36:2016, EN ISO 80079-
37:2016 and EN 1127-1:2019 were considered by an ignition hazard assessment. The applicable requirements of
these standards have been met.
For the European Union the documentation has been filed with TÜV-Nord-Cert NB 0044 (see Declaration of
Conformity).
