Reed Sensor Incorporated into a HIRSCHMANN connector

Characteristics

MK9 sensors are magnetically operated Reed proximity switches molded into a standard HIRSCHMANN connector casing according to "DIN43650/ type AM3". In combination with the corresponding Hirschmann socket a coupling with firmly defined position is achieved .  In order to fix the sensor, its molded surface is screwed on a plane surface in direction of the operating magnet.  The magnet is fixed to the moving part, e.g. a piston, which is traveling towards the sensor.  The Reed Switch is located in the completely molded socket.  The sensor is available in form A, B and C.

Applications

• Air filter maintenance
  e.g. monitoring of filter condition
• Air conditioning and clean room systems
  e.g. filter condition detection
• Pneumatic and hydraulic cylinders
  for position sensing
• Machine industry
