Magnetic Proximity Sensors High Repeatability type
H series
H Serise

H series sensors are suitable for a reference point sensor of a precision machine. Adopting a N-pole and S-pole borderline magnet as a reference point target magnet, H series sensor generates analog signal or switching signal. The repeatability at the borderline of N-pole and S-pole of target magnet is ±0.1µm.
