User Selectable Pulses per Revolution
The RH-P encoder, also known as a Pulse Position Indicator (PPI),
generates tracking pulses for web applications, and in particular for material handling sortation applications
when used with barcode laser scanners or CCD vision systems. The number of
pulses per each revolution of the wheel is selectable by setting configuration switches. 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
self-aligning 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 for
mounting the encoder from below.
