Meder MK7/1-1C90D-500W Cylindrical reed sensors with m8 thread Datasheet

MK7 Series
MEDER electronic
Cylindrical Reed Sensors
with M8 Thread
DESCRIPTION
MK7 sensors are magnetically operated Reed
proximity switches in a cylindrical form with an 8
mm x 0.75 thread and connecting cable or coupler.
The sensor can be screwed directly onto a fixed
surface with the actuating magnet on the moving
surface. The widespread termination “T” or “U” makes
the MK7 series compatible with several inductive and
magnetic proximity sensors.
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
• Other cables, connectors and colors available
• Various case sizes available
• Five operate sensitivities available
• A choice of cable terminations and lengths are
available
