Review: 中古の籾摺り機を購入しましたが、回転計が壊れたため、交換用に購入しました。 回転表示部は、ほぼ同じ大きさで四隅をやすりで少し削るだけで簡単に取付ができました。 センサー部は、配線が短く細いため、既存の配線と接続に手間取りましたが、何とか取付できました。
Review: Ho acquistato questo contagiri per completare la mia fresa a controllo numerico. occorre fare attenzione ai collegamenti del sensore di hall perché se alimentato al contrario si brucia. Il magnete in dotazione non è particolarmente potente, volendo una distanza di misura di 5 o 6 millimetri ho usato al suo posto un N50 rettangolare 10x5 mm. Attenzione al fissaggio perché un magnetino da un grammo se messo in rotazione a 10000 giri produce una forza centrifuga di diverse centinaia di grammi e schizza via e può far male.

## Questions & Answers

**Q: can you run the wires for power directly to the power switch on my wood lathe?**
A: Hello;   The requirement for the 4-digit counter is a DC voltage between 8 and 15 VDC.  Your switch, I presume, switches 120VAC to the lathe if you live in the U.S., and 240VAC if you live in Europe, England, or a few other countries.   It would make for a nice fireworks display if you connected this device to a higher AC voltage.
What I did was to buy a small 120VAC to 12VDC low current power supply, and it was about the size of a small box of matches, perhaps an inch (25mm) on the longest side.   The power supply and display come on with the switch, and report on my lathe's RPM just nicely.  I hope this helps, best of luck, Ken

**Q: what is the thread pitch of the Hall sensor threads**
A: 12 mm x 1 mm pitch.  Kind of an oddball size.  Hope this helps

**Q: Can I use a 3/16" or 1/4" dia. magnet that is longer, so I can drill a hole in a pulley, so it can't fly off?**
A: Your probably better off with a drop of 2 part epoxy or super glue.    By drilling the pulley and replacing with a different density material you may change the balance and induce vibration.   I just let the magnet hold it on my wood lathe shaft so far to 1200rpm.

**Q: I have a vfd suppling power to a 3 phase motor, the vfd has a terminal with 10vdc output connection but only allows 10ma is that enough power  to run**
A: Enough power to light up a small LED but nothing else.
