MK12 Series
MEDER electronic
Reed Sensors with Screw Fas-
tening Mounting Holes
DESCRIPTION
MK12 sensors are magnetically operated Reed
Sensors designed for screw mounting. The larger
casing permits the use of higher rated switches.
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.
APPLICATIONS
• Position and limit switch
Pneumatic or hydraulic actuator position
• End motion detection for linear drive
Indication and end travel limit switch
• Machine industry
End motion detection and door/flap control
FEATURES
• Form A, B, and C available
•High power switches available
• Other cables, connectors and colors available
• Various case sizes available
• Five operate sensitivities available
• A choice of cable terminations and lengths are
available
DIMENSIONS
All dimensions in mm [inches]
