FEATURES

The RH encoder, also known as a Pulse Position Indicator (PPI), generates tracking pulses for web applications when used with barcode laser scanners or CCD vision systems.
It typically is equipped with two 12 inch or 30 centimeter circumference measuring wheels that ride directly on the conveyor belt or web, eliminating any slippage problems typically encountered with shaft encoders.
With its double wheel construction, the encoder is selfaligning when allowed to pivot freely from its integral arm.
The encoder's weight is sufficient to maintain contact when mounted above the moving material.
Special mounting accessories are also available.
