MK10

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
