A3291KUA-T Hall Effect Sensor

The A3291KUA-T Hall Effect Sensor is a compact electronic component that detects the presence and change of a magnetic field and converts it into a usable signal. It is a popular choice for makers, electronics hobbyists, and automation projects where you need reliable, contactless sensing. Because it works without any physical touch, it is ideal for measuring position, proximity, rotation, or for triggering a switch when a magnet comes near. Whether you are building a DIY project, a robotics setup, or adding sensing to a control board, this Hall effect sensor gives you a simple and dependable way to read magnetic input.
