MK13 Series MEDER electronic Reed Sensors with Screw Fastening Mounting Holes DESCRIPTION MK13 sensors are magnetically operated Reed proximity switches in a case with an 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. FEATURES 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 • • • • • • 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 • High voltage versions upon request.
