Design a Custom BoardAbout This Component
Unipolar Hall-effect digital position sensor responding to magnetic fields, specifically the North pole variant. Operates at 350 G typical sensitivity with supply voltage range 3-24 VDC and temperature stability from -40°C to 150°C. Commonly used for door/lid detection, speed sensing, flow rate measurement, and position monitoring in motion control and industrial applications.
Package: SOT-23-3 · 3 pins
Why does this need a breakout?
SOT-23's tiny 0.95mm pin pitch and compact form factor make hand-soldering tedious and prone to bridging errors. A breakout board breaks out the three pins to standard 0.1" spacing for breadboard prototyping, eliminating the need for specialized soldering equipment and enabling fast circuit iteration with transistors, diodes, and small-signal components.
