Overview

Product Overview

The 49E Linear Hall Effect Magnetic Sensor is an analog magnetic field sensor that outputs a changing voltage as a magnet moves closer, farther, or shifts position, making it useful for position sensing, rotation detection, speed monitoring, and contactless control. Unlike a basic digital magnetic switch, this linear Hall effect sensor measures relative field strength for smoother feedback in robotics, automation, motor projects, and prototyping. It pairs well with Arduino, ESP32, and other microcontrollers with ADC inputs for magnet tracking, custom controls, and DIY sensing systems easily.
