1041936-01 RHA 507 SSI Hollow Shaft Adaptation

EncoderWorks provides a custom compatible replacement solution for 1041936-01 RHA 507 focused on maintaining SSI Gray communication behavior, Ø14 mm blind hollow shaft 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, signal interpretation, and the mechanical coupling conditions required by the existing control system. SSI communication can remain active while incorrect timing, signal mapping, or mechanical alignment still affects position accuracy.

System Limits

SSI replacement performance depends on maintaining consistent serial data transmission between the encoder and the controller. The 1041936-01 RHA 507 uses SSI Gray output with 13-bit singleturn resolution and a 5 VDC supply configuration. Clock timing, inverted clock/data signals, hold function, and code sequence settings must be matched because differences in serial data interpretation can result in incorrect position values or additional commissioning adjustments.

The mechanical integration boundary includes hollow shaft fit, stator coupling, and installation stability. This model uses a Ø14 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 feedback reliability in industrial applications.

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 inaccurate position evaluation.

During replacement installation, the Ø14 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 operating frequency requirements should be considered together to maintain reliable SSI feedback performance.
