Product Description
The 3144 Hall IC / Sensor is a reliable unipolar Hall effect sensor designed for precise magnetic field detection in automotive, industrial, and electronic applications.
This sensor operates by detecting a magnetic field from one pole only, and changes its output state accordingly. It is widely used in BLDC motors, speed detection, position sensing, and proximity switching.
The IC comes in a compact TO-92 package with three terminal leads: VCC (positive supply), GND (ground), and Vout (output). It provides a clean digital output signal for easy interfacing with controllers and circuits.
Due to its stable performance and fast response, the 3144 Hall sensor is ideal for high-speed and precision applications in EV systems and automation.
Designed for accurate and fast magnetic detection, this Hall sensor ensures reliable performance in demanding applications.
