The invention relates to a position sensor for a non-contact clutch, which solves the problems that the poor contact existing in the prior position sensor of the non-contact clutch leads to poor operational reliability and so on, The position sensor for the non-contact clutch comprises a shell, a rotor, a circuit board and so on, wherein a magnetic steel ring is arranged in the cylindrical rotor,the inner wall of the magnetic steel ring is symmetrically provided with two permanent magnet blocks respectively, and a cavity is formed between the two permanent magnet blocks; and the middle part of the circuit board is connected with an A Hall chip and a B Hall chip through two conducting member bars respectively, and the A Hall chip and the B Hall chip are positioned in the cavity between the two permanent magnet blocks. The sensor solves the problem of contact wear and prolongs service life; the sensor has good linear output characteristic and ensures that an output signal is more accurate and stable; the adopted Hall chips have functions of programmable property and temperature compensation, can flexibly change parameters of output voltage according to the requirement of customers,and automatically compensate and calibrate the magnetic field drift when the magnetic field intensity of a magnet drifts with the change of the temperature.
