Extech 461950 Panel Mount Tachometer
Speed checks remain steady and simple with the Extech 461950 Panel Mount Tachometer. Its microprocessor control keeps readings stable even during long runs, and the quartz crystal timing holds the pulse count firm. Clear LED output and rapid updates make it easy to follow fast-changing RPM levels in real time.
Sensor Options
Two sensor types give the unit flexibility across many setups. A proximity sensor reads a metal target at very close range, while a photoelectric sensor tracks a reflective mark with clean signal response. Each option arrives in a tough housing with a long cable, so mounting stays straightforward even in tight control panels. The Extech 461950 accepts both without extra modules.
Clear Readout and Control
A bright four-digit LED display makes readings visible in busy work areas, and the unit updates once per second when speeds exceed 60 RPM. It reads pulses produced by hole gears, discs, or simple metal studs, so there is no need for special wheels or complex adapters. In daily use the Extech 461950 sits securely in its cut-out and keeps data flowing without fuss.
Built for Daily Use
Standard 115 or 230 VAC input allows the tachometer to drop into most panel systems with no change to the power supply. The rugged body handles routine vibration and panel movement, while its compact depth suits shallow enclosures. These traits give the Extech 461950 long service life in workshops, labs, and production lines where constant RPM tracking is needed.
