Shaft Stub Information

The model HRS is an incremental hollow shaft encoder with up to a 1" (25mm) blind shaft bore in a standard 2-1/4" cube style housing that mounts directly on an existing shaft assembly.  A flexible mounting bracket allows the encoder to float on the shaft without rotating. The HRS generates up to 3 square wave outputs and can be configured as a single (A), quadrature (AB) or quadrature with index (ABZ) device.  Dual (AB) and triple (ABC) independent CPR outputs are also available.

Single output models can include the Anti-Jitter feature designed for conveyor and web systems requiring continuous and accurate measurement of the web’s movement even if the system must be stopped and restarted without reset. When the web stops, and if there is sufficient vibration or back-and-forth movement, then the encoder output could oscillate, appearing as if the web were actually moving. Anti-jitter eliminates this condition by significantly increasing the pulse hysteresis.

Features and Options:

  • Classic cube style
  • Bore size from 0.250" to 1.000"
  • Metric bore size from 10mm to 25mm
  • Resolution up to 1024 CPR
  • USAMade in the USA

Accessories

 

Cable Assembly (C6-x-10): 10ft. (3m), x condustor shielded cable & connector
Other lengths are available.
CE mark requires Photocraft cable, and surge protection if cable exceeds 100' (30cm) or leaves the building.

Flexible Mounting Bracket (MB-FB1): flexible stainless steel that allows for axial and angular shaft misalignment

 

Mounting Instructions

 

  1. Slide HRS onto shaft, fasten flexible mounting bracket or tether to frame, and then tighten shaft set screws.
  2. Atach the cable leads to the control device (e.g. PLC) ensuring that the power supply meets specifications.
  3. Attach the cable to the encoder.
