Feature

●After turning on the power and the sensor, the data can be read when the magnet is close to the sensor probe. note that the measurement range is 10~9999, if the speed is slow, it cannot be read.
●The Hall-type rotational speed sensor belongs to the Hall-type sensor and is made by the principle of Hall effect. The Hall effect is used to make the displacement of the Hall element move in the magnetic field to generate the Hall potential, that is, the displacement signal is converted into the potential change signal.
●The display will be based on the signal received by the Hall sensor and calculate the rotational speed of the measured device.Also displayed on the display.
●Hall sensor included: the Hall switch is NPN normally open and the detection distance of the Hall switch should be less than 10 mm. Hall switch installation diameter 12 mm, line length is less than 1 meter
●Application:Intelligent robot speed test;.Aircraft speed control;Product quality test;Factory;Production workshop;Store.

Use steps:
1>.Connect hall sensor to display as wiring diagram;
2>.Fix the magnet to the surface of the measured device;
3>.Adjust the shortest distance between the magnet and the sensor, and control it within 4mm;
4>.Rotate the device being measured;
5>.Connect power supply to display.

Note:
1>.Connect correctly according to the wiring diagram.
2>.It is recommended to use shielded wires or twisted pairs for measuring wires to avoid strong electromagnetic interference.
3>.It is recommended to use short wires to avoid excessive length of the wires, resulting in unpredictable interference.
4>.Mechanical switches or micros witches are not recommended.
5>.Please check if the test object is rotating at a constant speed and the installation is stable if the display data changes frequently.
