The SS40A Linear Hall Effect Sensor is a compact magnetic sensing component that produces an output proportional to the strength of a nearby magnetic field. As a bipolar linear device, it responds to both north and south magnetic poles, making it useful for sensing magnet position, motion, and proximity. It suits hobbyists, electronics students, automation builders, and anyone working on sensor-based DIY and project work.
Key features
- Linear Hall effect output that tracks magnetic field strength.
- Bipolar response to both magnetic pole orientations.
- SS40A model in a small, breadboard-friendly form factor.
- Easy to integrate with microcontrollers and common hobby boards.
Typical uses
- Magnet position and proximity detection.
- Speed, rotation, or motion sensing in DIY builds.
- Contactless switching and automation experiments.
- Educational electronics and prototyping projects.
How to choose / tips
- Confirm the SS40A fits your circuit voltage and wiring needs.
- Keep the sensor face aligned toward the magnet for the clearest reading.
- Use a suitable magnet strength and distance for your application.
- Pair with a microcontroller to read and process the analog output.
