Dart Controls, Inc. PU-4E 速度传感器

The PU-E Series pick-up is an economical and reliable way to monitor motor speed. Its patented design provides ease of installation in otherwise difficult to reach areas. The PU-E pick-up operates at a 5 to 24 volt level producing a sharp square wave output, which may be fed into Dart's field programmable tachometer, closed-loop control, counter, or any other digital device. The PU-E pick-up series also includes a quadra-ture model to monitor both motor speed and direction by providing two square wave output signals 81° out-of-phase.
