OCD-PPA1G-0710-C10S-PRT Bit Parallel and M27 Wiring

Matching OCD-PPA1G-0710-C10S-PRT requires more than reproducing the Ø10 mm shaft or clamp flange; EncoderWorks provides a custom compatible replacement where bit-parallel output behavior, 10/7-bit Gray-code scaling, latch and DIR wiring, M27 26-pin pin assignment, and solid-shaft alignment must be verified together. This replacement fails when the controller receives parallel bit states, but the bit order, latch timing, direction input, supply wiring, or shaft reference does not reproduce the original encoder behavior.

The OCD-PPA1G-0710-C10S-PRT is a multiturn absolute rotary encoder configuration with Bit Parallel interface, push-pull output driver, optical sensing, 10-bit singleturn resolution, 7-bit multiturn range, Gray code, mechanical geared multiturn technology without battery, 10–30 VDC supply, Ø10 mm x 20 mm solid shaft with single flat, clamp Ø58 mm flange, radial M27 male 26-pin connector, shaft IP66/IP67 protection, and housing IP65 protection. The controller should continue reading the same 17-bit parallel position structure.

The first failure boundary is bit-parallel data interpretation. Bit 1 through Bit 17 must be mapped in the same order, with Latch on pin 23, DIR on pin 24, Power Supply on pin 25, and GND on pin 26. If the PLC input card expects binary, serial SSI, or a different Gray-bit order, the encoder can switch normally while the calculated multiturn position is wrong.

This replacement fails when parallel outputs are present, but the controller reads the wrong absolute position because Gray-code decoding, bit order, latch behavior, DIR input, 10/7-bit scaling, or M27 26-pin assignment does not match the original encoder.

The second boundary is clamp-shaft mechanics. The Ø10 mm solid shaft, single-flat geometry, clamp flange, coupling alignment, radial connector clearance, shield grounding, shaft load, and IP sealing must be checked together. Cable strain or coupling preload should not be used to compensate for mounting error.

The replacement decision should first confirm Bit Parallel interface compatibility, push-pull input level, 10-bit singleturn and 7-bit multiturn scaling, Gray-code interpretation, Bit 1–17 mapping, Latch and DIR wiring, 10–30 VDC supply, M27 26-pin radial connector assignment, Ø10 mm solid-shaft fit, clamp-flange mounting, shaft IP66/IP67 sealing, housing IP65 sealing, and shaft-load limits. EncoderWorks treats OCD-PPA1G-0710-C10S-PRT as an industrial encoder custom compatible solution where parallel-bit mapping and shaft integration decide field reliability.

Typical production lead time: 15 working days.
