under conditions of strong
electro-magnetic influence As far as connection is concerned, it should be ensured that proximity sensor cables
are installed separately from supply lines to motors, switching valves etc.
If proximity sensor connection cables run over long distances in cable ducting or
cable trays parallel to other cables which conduct alternating currents or strong
current pulses, this can lead to interference with the proximity sensor via the
If the proximity sensors are used in areas of high interference (welding equipment,
motors, magnetic couplings, ...), the following steps are to be taken:
• Keep the connection cables of proximity sensors short
• Screen the sensor connection c...
