MEDER MK04-1B90-500W

MK04 Series
MEDER electronic
Reed Sensors
for Screw Fastening
DESCRIPTION
MK04 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
