Visi-Trak Worldwide delivers an industry-leading family of linear encoder transducers designed for reliable contactless monitoring in harsh environments. These transducers provide calibration-free installation while superior gapping allows glitch-free operation on imperfect or worn measuring targets. Whether a new installation or a retrofit, the A49-VT line is engineered to perform and designed to last.
The transducer is encased in a non-ferrous, stainless-steel housing and utilizes a magnetic field to detect movement of a threaded steel rod made smooth by chrome plating. These movements, indicating target speed and direction, are quadrature encoded and transferred over a two-wire interface where a decoder computes instantaneous speed and direction using the known target thread pitch. This information provides valuable feedback for a variety of monitor and adaptive control applications. Visi-Trak offers four transducer models designed to work with commonly available pitch widths. For best performance, use Visi-Trak measurement rods and mounting hardware.
