Meaning that voltage/current are allowed to pass only when the magnet is near the sensor. For use as a tachometer, you would be reading pulses/second, or frequency. So data logging voltage wouldn't really work unless you worked some excel magic afterwards. **Q: what is the maximum length of the sensor wire? 44 inches is too short for my need. Can I lengthen it?** A: I installed this on my combine to measure the fan RPM speed. I needed to add more wire to reach the display mounted inside the cab. The total length of the wire is over 15 feet. I believe it would work at even a greater length. The unit works great. ## Frequently Bought Together - DIGITEN 4 Digital Red LED Tachometer RPM Speed Meter + Hall Proximity Switch Magnet Sensor NPN for Lathe Conveyor Belt - DIGITEN 4 Digital Red LED Tachometer RPM Speed Meter + Hall Proximity Switch Magnet Sensor NPN + Sensor Mounting Holder for Lathe Conveyor Belt - DIGITEN 4 Digital LED Tachometer RPM Speed Meter+Hall Proximity Switch Sensor NPN Blue --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/439202626-digiten-4-digital-led-tachometer-rpm-speed-meter-hall-proximity](https://www.desertcart.sc/products/439202626-digiten-4-digital-led-tachometer-rpm-speed-meter-hall-proximity) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-01*
