What Is a Hall Effect Sensor?
A Hall Effect sensor detects changes in a magnetic field and converts them into an electrical signal. In electric bikes, it is used inside the motor or controller to monitor rotor position and RPM, allowing the controller to manage power delivery and speed with precision.
Who Is This For?
This sensor is ideal for e-bike mechanics, DIY electric bike builders, and riders who maintain their own controllers. It is a direct replacement for worn or faulty 502F or 3144 Hall sensors found in most brushless DC motor controllers.

Frequently Asked Questions
Q: What e-bike controllers are compatible with the 502F / 3144 Hall Effect speed sensor?
A: This Hall Effect speed sensor is compatible with most standard brushless DC electric bike controllers that use 502F or 3144-type Hall sensors. These are among the most common Hall sensor pinout configurations found in Chinese-manufactured e-bike controllers. Always verify your controller's Hall sensor specifications before purchasing.
Q: How do I install the PCB Hall Effect speed sensor on my e-bike controller?
A: Installation involves identifying the Hall sensor slot on your e-bike controller's PCB, removing the faulty sensor, and soldering or plugging in the new 502F / 3144 PCB sensor in the correct orientation. If you are not experienced with electronics, we recommend consulting a qualified e-bike technician for installation.
Q: Is this sensor suitable for both RPM monitoring and speed detection?
A: Yes. The Hall Effect sensor detects changes in the magnetic field generated by the motor's rotating magnets, producing a signal pulse that the e-bike controller uses to calculate both RPM and wheel speed accurately.
