Hollow Shaft Encoder - HRL-P Series
HRL-P - Hollow Shaft Encoder with User Selectable Pulses per Revolution

The model HRL-P is an optical hollow shaft encoder with up to a 1" / 25mm blind shaft bore in a heavy duty aluminum 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 number of pulses per revolution is determined by setting configuration switches accessible through an access port near the connector. Any one of a predefined set of pulses per revolution are available.

Standard Features and Options:
•  10-foot / 3-meter cable included at no extra charge
•  CE Marked
•  Surge protection available

ACCESSORIES

• Flexible Mounting Bracket (MB-FB1): allows for axial and angular shaft misalignment.
• Cable Assembly (C5-x-l0): 10ft. (3m) shielded cable with 97-3106A14S-5S mating connector is included at no extra cost (x is number of conductors) Other lengths are available. 
  CE marking requires Photocraft cable, and surge protection option if the cable exceeds 100' (30m) or leaves the building.
