Hollow Shaft that fits up to 1" (25mm) diameter shaft

The model HRL is an optical hollow shaft encoder with up to a 1" / 25mm blind shaft bore in a heavy duty aluminum style 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 HRL generates up to 3 square wave outputs.
