Meder Electronic MK10 Series Reed Sensor with Integrated Resistor DESCRIPTION MK10 sensors are magnetically operated Reed proximity switches in which a small size resistor is integrated into the package. The single-in-line construction is designed for PCB mounting. The magnetic pull-in / drop-out sensitivity is divided into two AT ranges. APPLICATIONS RESISTOR VALUES • All standard values of 1/8 Watt resistors of the series E96 with 1% tolerance are available as well. FEATURES • Ideal for level sensing • Banks of keys with resistance matrix • The integrated resistor can be used for contact protection • High power switches available • Small dimensions PIN OUT DIMENSIONS All dimensions in mm [inches] ORDER INFORMATION SENSITIVITY CLASS PULL IN AT RANGE B 10 - 15 C 15 - 20 SERIES MAGNETIC SENSITIVITY RESISTANCE IN OHM MK10 X - XXX OPTIONS B, C * * All standard values of 1/8 Watt resistors of the series E96 with 1% tolerance can be built in. Part Number Example MK10 B - 390 B is the magnetic sensitivity, 390 is the resistance in Ohm * www.willow.co.uk Tel. +44 (0) 1342 835234 Fax. +44 (0) 1342 834306 MK10 Series Meder Electronic Reed Sensor with Integrated Resistor CONTACT DATA All data at 200 C Switch Model --> Contact Form --> Contact Ratings Conditions Contact 87 Form A Min.
