Rotational speed sensor

Hall effectanalog outputnon-contact

Hall effect speed sensors detect the rotary motion of any ferrous object with cracks or projections, typically gears and tone wheels. They incorporate a back-polarised Hall effect chip which detects the variation in the magnetic field according to the full/empty position of the wheel and provides a digital frequency signal at the output. In the double output versions, by reading the two signals A and B, it is possible to determine the clockwise or anti-clockwise direction of rotation: in particular, the direction of rotation can be determined from the advance or lag phase between two square-wave signals or from a switching signal. The speed sensors with adjustable thread are the most flexible version for mounting, as they allow the position to be adjusted to the desired point by screwing. SUITABLE FOR agricultural machinery, earth moving machinery, load lifting vehicles, axles and transmissions, vehicles for moving loads, special purpose industrial vehicles, automotive sector, electric vehicles, railway sector.
