## Questions & Answers

**Q: Would this be suitable for a tachometer up to 4000 rpm ?**
A: No this would not be suitable for this application.  For a Tachometer at this speed you need a contactless sensor - normally a small magnet attached to the rotor and a hall sensor to detect the magnetic pulse at each rotation.
