Induktiva givare

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 67 even permits safe application under rough ambient conditions. In addition, Ex inductive sensors are available with plug-in connectors for equipment category 3D, dust Ex zone 22.
The Ex IS M12/M18/M30 range is offered as a complete system with a relay module. The relay module, which is suitable for cabinet mounting, supplies the required intrinsic power for the sensor and transmits the sensor signal.
The function of the input circuit can be programmed as NO or NC contact. The LEDs of the Ex RM 1W 1 relay module indicate the operational condition of the sensor, as well as possible malfunctions such as wire breakages and short-circuits. All Ex inductive sensors shown in this chapter bear the CE mark according to the EMC Directive 2004/108/EC and according to ATEX 94/9/EC. The Ex safety switches for hinged guards per equipment category 3D bear the CE mark without the number of the notified body and have received a CE declaration of manufacturer conformity.
