Hollow Shaft Encoder - HS20-P Series
HS20-P - Up to 5/8" / 16mm Diameter Hollow Shaft

The model HS20-P is an optical hollow shaft encoder in a 2" diameter housing that mounts directly on an existing shaft assembly. A flexible mounting bracket or tether allows the encoder to float on the shaft without rotating. The HS20 generates up to 3 square wave outputs.
The encoder is factory configured with a program that offers one or more features. DIP switches are used to set program parameters. 

Standard Features and Options:
•  Dip switch selectable features
