Dimensions

See also HS20-P Programmable
and R20 Shaft Encoder

Up to 5/8" / 16mm Diameter Hollow Shaft

The model HS20 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.
