Product Description
The model HS20 is an industrial strength programmable hollow shaft encoder in a 2" housing that mounts directly on an existing shaft assembly. When attached to a flexible mounting bracket or tether the encoder floats on the shaft without rotating. The encoder is factory configured with a program that offers one or more features. DIP switches are used to set program parameters. Available programs are listed below.
Some of the available features are:
Selectable CPR
Quadrature (A/B) outputs
Direction output
Anti-jitter feature
