The working pinciple:
Reed sensor is applicable for position determination of pneumatic and /or hydraulic cylinder and piston pump. It also can be used a slimit switch. When the magnetic object approaches, the reed closes and sends out switch signal through magnification. Compared with inductive sensor. it has the following strongpoints: can be installed in metal closely and side by side and detect through metal object. Its detection distance subjects to the intensity of magnetic field of detected object. Reed sensor is not applicable in the occasion of severe vibration.
