AX103121 can provide accurate wheel speed and position information by detecting wheel pulses while saving customer costs. This type of sensor can measure the position and pulse rate of a tooth wheel mounted on a machine and provide information to the control system. It is used for measuring rotary and linear motion of various machinery, and can be widely used in industrial automation, automobile, robotics and other fields.

The basic principle of the AX103121 is the eddy current induction principle. In the application of the eddy current induction, when an alternating current is passed through the primary winding of the induction transformer, an alternating magnetic field is generated, which in turn produces eddy currents in the metal under test. The metal object acts as the secondary winding of the induction transformer. When it moves relative to the primary coil, the eddy current caused by the time-varying magnetic field in the primary coil will also generate inductive voltage in the metal object. Due to the action of the second induction coil, the SR signal corresponding to the rotation speed of the measured pulse wheel can be output from the eddy current sensor.

After the pulse wheel rotates for one revolution, the eddy current sensor will output a corresponding pulse signal to the control system, each pulse signal width corresponds to the pulse wheel rotation angle. In order to obtain the position and speed information of the pulse wheel, the pulse counting and pulse frequency are needed. The control system counts and uses the signal to obtain the pulse wheel position.

The general configuration of AX103121 includes two parts, the first is the pick-up device, the second part is the output circuit. The pick-up device is the core of the device, including the primary coil, secondary coil, eddy current vibrator and other components. It is installed on the surface of the measured pulse wheel. The output circuit uses the signal from the pick-up device to generate the SR signal corresponding to the rotation speed. The signal is transmitted through the line and output to the control board.

The signal output by the eddy current sensor is mostly used to measure rotational speed and position of a wheel, as well as linear speed and position. Once the sensor fails, it will cause the device to work abnormally, so it is very important to choose a reliable and high quality eddy current sensor. The eddy current sensor AX103121 is used in many industries, and its application is wide ranging. It can provide accurate speed and position signals for industrial automation, robotics, automobiles, and other fields.
