1. Working voltage: 3.3-5 v 2. Use the model 3144 e switch hall sensors. 3. When the sensor to the magnetic field sensors, digital output low level, signal lights; If it weren't for induction magnetic field, the digital output high level, the light is not bright. 4. Has the power light and signal light. 5. The output format: digital switch output (0 and 1) AO mouth is invalid 6. Adopt the LM393 comparator output model is clean, good waveform, driving ability is strong, for more than 15 ma. 7. Equipped with fixed bolt hole, convenient installation. 8. Can be used for motor speed and position detection, etc.
The sensor function is introduced:
3144 hall switch integrated circuit using hall effect principle of the semiconductor integrated technology manufacturing magnetic susceptibility of the circuit, it is by the voltage regulator, hall voltage generator, differential amplifier, schmidt triggers, temperature compensation and the open collector output stage circuit composed of magnetic sensitive sensor circuit, its input for the magnetic induction intensity, the output is a digital voltage signal.
The sensor has the following features: small volume, high sensitivity, fast response, good temperature performance, high precision, high reliability.
