MK09 Series MEDER electronic Reed Sensor Incorporated into a Hirschmann Connector DESCRIPTION MK09 sensors are magnetically operated Reed proximity switches potted into a standard Hirschmann connector casing according to “DIN 43650 / type AM3”. In combination with the corresponding Hirschmann socket a coupling with firmly defined position is achieved. In order to fix the sensor, its potted surface is screwed to a flat surface in the direction of the operating magnet. The magnet is fixed to a moving part which is travelling towards the sensor. APPLICATIONS FEATURES • Air filter maintenance Monitoring of filter condition • Air conditioning and clean room systems Filter condition detection • Pneumatic and hydraulic cylinders Position detection • Machine industry • • • • Form A, B and C available High power switches available Five operate sensitivities available High voltage versions upon request DIMENSIONS All dimensions in mm [inch] www.meder.com 234 MEDER electronic MK09 Series Reed Sensor Incorporated into a Hirschmann Connector ORDER INFORMATION Part Number Example MK09 - 1A66 Series Contactform Switchmodel Magnetic Sensitivity MK09 - 1A XX X 66 B, C, D, E 85 B, C, D, E 90 C, D, E C 1A is the contact form 66 is the switch model C is the magnetic sensitivity 1 Form A Options 1 Form B 1 Form C MAGNETIC SENSITIVITY Sensitivity Class Pull In AT Range B 10 - 15 C 15 - 20 D 20 - 25 E 25 - 30 PIN OUT www.meder.com 235 MEDER electronic MK09 Series Reed Sensor Incorporated into a Hirschmann Connector CONTACT DATA Switch Model → Contact Form → All Data at 20° C Contact Ratings Conditions Switch 66 Form A Min.
