KJT magneto-electric speed sensor operates on the principle of electromagnetic induction to measure rotational speed. As the gear rotates, the magnetic flux lines passing through the sensor coil change, generating a periodic voltage within the coil; the amplitude of this voltage correlates with the rotational speed—higher speeds result in higher output voltages (within the 0–a range)—while the output frequency is directly proportional to the speed. Featuring a specialized coil design for enhanced interference resistance, the sensor is widely used. It delivers a strong output signal, offers excellent resistance to interference, requires no external power supply, and is easy to install and use.
