Cylindrical
Reed Sensors
DESCRIPTION
MK20/1 sensors are magnetically operated Reed
proximity switches in a cylindrical module, fitted with
interconnect cable. 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
FEATURES
Pneumatic or hydraulic actuator position
Indication and end travel limit switch
• Door and window contacts
Security system applications
• Flat side indicates maximum sensitivity
• Small size
• Other cables, connectors and colors available
• Three operate sensitivities available
• A choice of cable terminations and lengths are
available
• Level sensor
Use with magnetic floats for water level detec-
tion in coffee makers, washing machines or
dishwashers
