Meder MK12P1C52E-500W Reed sensors with mounting holes for screw fastening Datasheet

MK21 Series
MEDER electronic
Reed Sensors with Mounting
Holes for Screw Fastening
DESCRIPTION
MK21 sensors are magnetically operated Reed
proximity switches designed for screw mounting.
The sensor should be mounted on a fixed surface
with the actuating magnet on the moving surface.
Introduction or removal of the magnetic field
determines the closing and opening of the Reed
Switch. Leads are Teflon coated. Designed for
extreme environment. Resistant to water, fuels,
oils, inks and most acids.
APPLICATIONS
