MK19 Series

Reed Sensors in Tall Package for PCB Mounting


MK19 sensors are magnetically operated Reed proximity switches in a tall stand off package for PCB mounting. The sensor should be mounted on a fixed surface with the actuating magnet, e.g. M3, on the moving surface.  Introduction or removal of the magnetic field determines the closing and opening of the Reed Switch.
