Meder MK21-1A66C-500W Reed sensors with mounting holes for screw fastening Datasheet

MEDER electronic
MK21 Series
Reed Sensors with Mounting
Holes for Screw Fastening
DESCRIPTION
MK21 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. Leads are teflon coated. Designed for extreme
environment. High temperaturs, 150 °C Imprevions to
water, fuels, oils, inks and most acids.
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
