The output signal of this type of sensor is processed by a pulse comparator integrated in the device.
The frequency of the pulses Fc emitted by the moving element to be monitored is compared with the frequency Fr preset on the device.
The output switching circuit of the sensor is at closed state when Fc > Fr and open state when Fc < Fr.
XSA-V sensors are particularly suitable for underspeed detection: when the speed of the moving element to be monitored Fc falls below a preset threshold Fr following deceleration, this detection leads to opening of the device's output circuit.
