Magnetic field sensor Hall effect KY003

Magnetic Hall Effect Sensor Consists of an integrated circuit 3144UA to detect magnetic fields (for example a magnet) detects and closes like a switch when the magnetic field of an object (for example, a magnet) indicates this detection by closing the pin «S« to ground, which is The collector of an NPN transistor without bias resistor. The operating method is based on the Hall effect. The "S" pin is the detection signal and corresponds to the pin on the right, the center pin is the positive of the power, and the left pin is the negative (marked “–”). ■ Working voltage is from 4.5 to 24 volts VDC ■ Consumes 3 mA at idle and 8 mA when it detects a magnetic field ■ The output signal voltage depends on the polarization resistor connection (Pull-up): 3.3V, 5V ■ Working temperature ranges from -40 to 85 degrees C. ■ Dimensions: 18.5 mm x 15 mm
