Meder Electronic MK9 Series Reed Sensor Incorporated into a Hirschmann Connector DESCRIPTION MK9 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 • Air filter maintenance Monitoring of filter condition • Air conditioning and clean room systems Filter condition detection • Pneumatic and hydraulic cylinders Position detection • Machine industry FEATURES • Form A, B and C available • High power switches available • Five operate sensitivities available DIMENSIONS All dimensions in mm [inches] www.willow.co.uk Tel. +44 (0) 1342 835234 Fax. +44 (0) 1342 834306 MK9 Series Meder Electronic Reed Sensor Incorporated into a Hirschmann Connector ORDER INFORMATION SERIES CONTACT FORM SWITCH MODEL MAGNETIC SENSITIVITY MK9 - XX XX X 71 B, C, D, E 81 A 84 B, C, D, E 90, 96 C, D, E 1 Form A OPTIONS 1 Form B 1 Form C Part Number Example MK9 - 1A71 C 1A is the contact form 71 is the switch model C is the magnetic sensitivity MAGNETIC SENSITIVITY SENSIT IVITY CLASS PULL IN AT RANGE A 5 - 10 B 10 - 15 C 15 - 20 D 20 - 25 E 25 - 30 PIN OUT www.willow.co.uk Tel. +44 (0) 1342 835234 Fax. +44 (0) 1342 834306 Meder Electronic MK9 Series Reed Sensor Incorporated into a Hirschmann Connector CONTACT DATA Switch Model --> Contact Form --> All data at 20 0 C Contact Ratings Conditions Contact 71 Form A Min.
