RS-3 Hall inverse speed sensor uses hall element, is actuated by magnetizer of steel and iron, wide frequency response, good stability, strong capacity of resisting disturbance. Inner amplified wave-shaping circuit, output stable square wave, long distance transmittance. There are two hall sensors at 1800 angle, output 2 ways stable square wave with angle different, can measure speed and know direction of gear rotating.
