Packaging include Tachometer x 1 Hall NPN proximity sensor x 1 Review: Tachometer - Good product - Good product. Works well and appears very accurate Review: Excellent....it works and sensible price - I’m very pleased with this...it’s been added to a metalworking lathe as attached photos. In order to keep things out of the way and clear of oil and swarf, the magnet is glued to the spinning knob at the rear of the headstock and the sensor is mounted in a wooden block underneath it, at an angle so that it’s roughly at right angles to the magnet face. The counter is also mounted at an angle in a wooden block, which allowed all the connections to be neatly inside. Both wooden blocks are held down with Velcro so that they can be removed and repositioned easily. Straightforward to fit...could be done simpler but I wanted it to be neat and out of the way. But it’s really good. I’m running mine off a 12v supply. A stronger magnet would allow the sensor to be placed further away...I did experiment but used the supplied one in the end because although I do have much stronger ones available, the supplied one did work at the required distance and it’s quite thin so doesn’t create much of a projection on the knob. I’m so pleased with this that I’ve just ordered another one as a spare! Recommended. Ps...as others have said, you need to get the magnet the right way up or it won’t work! ## Features - Measure range: 5-9999RPM. - Power requirement:DC 8-15V - Come with hall sensor and magnet - Display:red 0.56" LED - Application: Lathe, CNC, Mower, Spring, etc.Measure varied motor RPM. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01FQMI18Y | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 17,175 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 3 in Motion, Speed & Force | | Colour | Green | | Customer Reviews | 4.3 4.3 out of 5 stars (627) | | Date First Available | 16 May 2016 | | Item Package Quantity | 1 | | Item Weight | 99 g | | Item model number | 5823950920 | | Manufacturer | DIGITEN | | Material | Wood | | Part number | RPM1204GHA | | Product Dimensions | 7.11 x 2.03 x 3.56 cm; 99.22 g | | Voltage | 12 Volts | ## Product Details - **Brand:** DIGITEN - **Item dimensions L x W x H:** 7.1 x 2 x 3.6 centimetres - **Item weight:** 3.5 Ounces - **Material:** Wood - **Voltage:** 12 Volts ## Images ![DIGITEN 4 Digital Green LED Tachometer RPM Speed Meter+Hall Proximity Switch Sensor NPN - Image 1](https://m.media-amazon.com/images/I/71V-TVeOTXL.jpg) ## Questions & Answers **Q: What current input does the meter require? My inverter can supply a 24V, 20mA digital supply will this suffice.** A: Hi The unit is a great item I have got It on a three phase lathe the unit as stated requires 8-15 volts dc I fitted a 240v ac adjustable power adapter and set t to 12 volt dc .if you go above 16 volts it can blow. Hope this helps Jem C **Q: Can i use a 12v 1a switch mode led psu to drive the display?** A: Yes, 1A is enough. **Q: Where does the sensor fit on a V twin Honda Aero motor cycle** A: I would think the DIGITEN 4 Digital Green LED Tachometer RPM Speed Meter+Hall Proximity Switch Sensor NPN is not going to be easy to install on a motor bike.You will need to mount the magnet that's provided to something that rotates with the crankshaftso the hall effect pick up sends 1 pulse per revolution to the rev counterthe magnet needs to pass within 1 or 2 mm from the sensorthe automotive tachometers I've seen either connect to the connection between the contact breaker (or electronic ignition module ) & HT coil or use a pick up mounted to a spark plug cable **Q: Does it come with instructions how to wire it up?** A: Yes, it come with instructions it tell you how to wire. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Tachometer - Good product *by A***R on 9 December 2025* Good product.
