## Questions & Answers

**Q: the speed of my sprocket maybe in excess of 4000 rpm, will the magnet hold on at this speed or should I glue it**
A: Glue it close to shaft. Another option is use something like this: LJ12A3-4-Z/BX Metal Detecting NPN NO 3 Wire DC 6-36V 
This is an inductive sensor which doesn't need a magnet but you can pick up on a bolt head which is what I did for my disco so that I could tell which wheel had lost traction

**Q: How close does the magnet need to be to the sensor?**
A: Their customer support replies promptly to queries. They said, in email to me, 2-3mm is best - with south pole pointing at sensor. The leaflet with unit and spec says 10mm.

**Q: Can this unit be used with a diesel engine**
A: Depends what you want to measure? This unit's sensor can be placed next to any rotating equipment (as long as there is space for a bracket, with the magnet on the rotating part) and measures RPM only. Would connect directly to 12V DC supply of a car battery/alternator.

As described

### ⭐⭐⭐⭐⭐ Decent size display
*by M***T on 13 September 2023*

Bought to monitor the speed of my old Myford lathe. Easy to wire up but ideally needs to be built into a box to protect the electronics and connections.You also need an external low voltage main’s adapter to power it, and it’ll work with any 8-15v DC supply ( I used a spare 12v one )The transmitter unit has a decent amount of thread on it to adjust the distance to the magnet which is fixed to the moving part.

### ⭐⭐⭐⭐⭐ magnet needs to be round right way
*by D***K on 25 September 2018*

Excellant product i fitted to my Sieg SC2 lathe no problem atall.I used a multi volt charger for power and stripped it down to fit inside control box . Took live feed from inside controll box.all very neat.Before fitting magnet pernament its got to be round right way.Saved me the cost of £179 for plug in Sieg one
