MK05 Series
Reed Sensors
with Screw Fastening Slot
MEDER electronic
DESCRIPTION
MK5 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.
APPLICATIONS
•
Position and limit switch
Pneumatic or hydraulic actuator position
indication and end travel limit switch
•
Door and window contacts
Security system applications
•
Level sensor
Use with magnetic floats for water level
detection in coffee makers, washing
machines or dishwashers
FEATURES
Form A, B, and C available
High power switches available
