## Questions & Answers

**Q: is this omnipolar, unipolar or bipolar?**
A: Unipolar only

**Q: Can this sense a strip of magnetic tape?**
A: Theoretically yes, if it's the proper polarity as this only detects a single polarity and ignores the other.

**Q: Is there any reason why this would not work with an ebike controller in place of the typical external hall speed sensor?**
A: This is just on/off, I suspect the hall speed sensor is more complicated than that. But if you're replacing a single on/off sensor, and can provide the proper power to it... and the controller only needs the single signal wire... it may work.

**Q: Is the provided magnet necessary to register a reading?  What is the detection distance when working with materials such as aluminum and steel?**
A: This can only sense the magnet
