The device features an IP54/NEMA-12 enclosure and is used for tracking, storage and retrieval, pick-and-place, conveying, and elevating for material-handling applications.

The Series RH wheeled encoder, known as a Pulse Position Indicator (PPI), generates tracking pulses for web applications when used with bar-code laser scanners or CCD vision systems. The unit is equipped with 12-in. or 30-cm-circumference measuring wheels that ride directly on the web or conveyor belt to eliminate slippage. The encoder is self-aligning when allowed to pivot freely from its integral arm.
