Range of application

Ex inductive sensors are suitable for the positioning and controlling of machines and systems in many areas with explosive endangered industrial applications.

They are generally used as an alternative to mechanically operated limit switches in cases where unfavourable operating conditions, such as high or low actuating speeds, large switching frequencies, extreme dirt or dust production, high humidity, chemical atmospheres, highly fluctuating actuating distances, etc., occur. Even in the presence of aggressive materials, safe switching is ensured through encapsulation of the contacts.

Design and mode of operation

The Ex inductive sensors change their current consumption or their internal resistance with the approach of metal to the sensor surface. As output signals the changed current or the changed internal resistance are available. The degree of protection IP 68 even permits safe application under rough ambient conditions.

The Ex inductive sensors shown in this chapter bear the CE mark according to the EMC Directive 2014/30/EU and according to ATEX 2014/34/EU.
