1041932-01 RHA 507 SSI Hollow Shaft Compatibility

For systems using 1041932-01 RHA 507, EncoderWorks provides a custom compatible replacement solution focused on maintaining SSI Gray communication behavior, blind hollow shaft mechanical adaptation, and singleturn position data consistency. The replacement challenge is not only matching the 13-bit absolute feedback output, but also preserving SSI clock/data timing, Gray code interpretation, and the mechanical coupling conditions required by the existing position control system.

System Limits

SSI replacement reliability depends on maintaining consistent serial communication between the encoder and the controller. The 1041932-01 RHA 507 uses SSI Gray output with 13-bit singleturn resolution and a 5 VDC supply configuration. Clock timing, data format, inverted signal handling, and code sequence settings must be matched because the controller may receive SSI signals while incorrect data interpretation still causes position errors or additional commissioning effort.

The mechanical integration boundary includes hollow shaft fit, stator coupling, and installation stability. This model uses a Ø10 mm blind hollow shaft with a 58/59 flange and stator coupling structure. Shaft engagement, coupling alignment, cable routing, shielding, and grounding continuity should be maintained because mechanical mismatch or electrical interference can affect long-term position feedback accuracy.

Wiring & Installation

SSI integration requires verification of clock, inverted clock, data, inverted data, hold, code sequence, and shield connections. The configuration uses dedicated SSI clock and data lines with additional hold and code sequence functions. Incorrect signal mapping, missing inverted signal connections, or insufficient shielding continuity may result in unstable serial communication or incorrect position evaluation.

During replacement installation, the Ø10 mm blind hollow shaft and stator coupling interface should be checked against the existing machine structure. The hollow shaft engagement, flange mounting condition, cable routing, and vibration environment should be considered together to maintain reliable SSI feedback performance in industrial applications.
