Product overview
The 42HSE series combines a 42mm square mounting flange with encoder feedback for closed-loop motion control in compact equipment. Select the body length, holding torque and shaft diameter for your load, available space and drive configuration. Closed-loop operation requires a compatible driver; the supplied catalog lists HSE57.

| A+ | Red |
| A− | Blue |
| B+ | Green |
| B− | Black |
| Encoder pin | Wire color | Signal |

| 11 | Yellow | EB+ |
| 12 | Green | EB− |
The encoder uses a DB15 connector. Verify wiring by pin number rather than connector orientation. Confirm encoder supply voltage against the driver specification; no supply value is stated in the supplied catalog.
Speed and torque
The supplied speed–torque curves were measured at 24 VDC. Running torque decreases as speed increases; holding torque is not the available output torque at every speed. Actual performance depends on the driver, supply and load.
Installation precautions
- Do not strike the shaft when installing or removing shaft-end components; impact can damage the encoder at the opposite end.
- Minimize shaft-seat vibration to protect the bearings.
- Customization is available. Confirm the model, shaft, mounting dimensions, cables and driver compatibility before ordering.
