MK10 Series

Magnetically operated Reed Sensor with integrated resistor


MK10 sensors are magnetically operated Reed proximity switches in which a metal film resistor can be integrated on request.  The single-in-line construction can be mounted on all pcb’s.  The magnetic pull-in / drop-out sensitivity is divided into two AT ranges.  All standard values of 1/8 Watt resistors of the series E96 with 1% tolerance can be built in.  The small dimensions are another important feature of the MK 10 series.


The integrated resistor can be used for contact protection at suitable optimization
