Series 20 with Heavy Duty Bearings
The model R20-P is an optical shaft encoder in a 2" diameter
x 1-3/4" long housing that can be face mounted using three 6-32 x .25"
deep mounting holes on a 1.75" diameter bolt circle. The shaft is up to 3/8"
diameter, either single or double ended. Electrical connection is through a 16mm
circular connector or an attached cable.
The encoder is factory configured with a program that
offers one or more features. DIP switches are used to set program parameters.
Examples of some of the available features are: selectable pulses per
revolution, quadrature (A/B) outputs, direction output, and the anti-jitter
feature.
