HRE-58 / DIRECT MOTOR FEEDBACK
Hollow Shaft Rotary Encoders
Through-bore and blind-bore incremental feedback for motor shafts, packaging lines and rotary axes.
Ø6–15 mm / ¼″–⅝″ requests
100–10,000 PPR · HTL / TTL
BORE ID × HOUSING OD × OUTPUT
Match the shaft before the signal.
Start with the shaft diameter, insertion length and clamp access. Then match the ABZ output circuit to the controller input.
| Model | Hollow bore ID / mounting | Housing OD | Resolution | Output circuit / protocol | Max RPM |
|---|---|---|---|---|---|
| HRE-58T | Through · Ø6 / 8 / 10 / 12 / 14 / 15 mm | Ø58 mm target | 100–10,000 PPR request | HTL 10–30 V / TTL 5 V RS422 | Confirm by PPR & output |
| HRE-58B | Blind · ¼″ / ⅜″ / ½″ / ⅝″ request | Ø58 mm target | 100–10,000 PPR request | ABZ / differential ABZ | Confirm by configuration |
Configuration request envelopes, not a released datasheet. Max RPM, exact bore, housing, resolution and protocol combinations require written confirmation. Inch and metric sizes are distinct.

Bring the machine constraints into selection before ordering a prototype.
- Shaft tolerance, runout, usable length and through-bore clearance
- Clamping collar access and flexible stator tether travel
- Supply voltage, differential or single-ended ABZ and maximum input frequency
01 / CHOOSE THE MECHANICAL INTERFACE
One shaft. Three ways to read it.
Through-hollow
A continuous bore lets the shaft pass through the encoder. Check clamp access and shaft clearance.
Blind hollow bore
A closed bore fits the shaft end. Check insertion depth and avoid bottoming out the shaft.
Shaftless ring kit
A ring and readhead use the machine bearing. Check sensing gap, runout and calibration.
Original engineering concepts. Not to scale; final housing, ring and mounting dimensions require an approved drawing.
HRE-58 / ENGINEERING QUESTIONS
Resolve the fit before release.
Are 15 mm and ⅝ inch the same bore?
No. ⅝ inch is 15.875 mm. Specify the exact shaft size and tolerance; do not force a metric bore over an inch shaft.
Does a hollow mount eliminate every source of backlash?
It removes a separate coupling from the layout. Clamp slip, tether compliance, shaft runout and bearing condition still affect the assembled system.
