OCD-PPA1B-0013-B060-CAW Parallel Encoder with Ø6 Blind Hollow Fit

A replacement page for OCD-PPA1B-0013-B060-CAW should not be differentiated by interface or resolution, because its real boundary is the ø6 mm blind-hollow mounting inside a 13-bit binary parallel feedback system; EncoderWorks can configure a custom compatible replacement solution when the Bit 1–13 wiring, latch timing, DIR logic, push-pull level, axial cable shielding, and shaft-clamp fit must remain unchanged. The main failure risk is a clean binary position signal combined with wrong bore fit, clamp preload, or bit order. Typical production lead time: 15 working days.

This configuration is used where a controller reads absolute singleturn position directly through parallel inputs instead of SSI, Profibus, PROFINET, EtherNet/IP, or incremental A/B/Z signals. The encoder combines 13-bit singleturn resolution, binary output code, push-pull driver behavior, a ø58 mm blind-hollow flange, ø6 mm blind-hollow shaft, and a 1 m axial PVC cable. Replacement work should focus on Bit 1–13 assignment, binary value interpretation, controller input threshold, latch response, DIR input state, cable-core identification, shaft insertion depth, clamp force, and shield continuity.

System Limits

The first system limit is 13-bit binary mapping. Bit 1 through Bit 13 must remain connected to the same controller inputs as the original encoder. If one bit is shifted, inverted, or assigned to the wrong input, the PLC may receive a stable but incorrect absolute position value.

The second limit is sampling and code interpretation. This model uses binary code, not Gray code. If the controller expects Gray-code conversion, or if latch timing does not match the scan window, the position value can jump during motion, startup, or reference checks.

The mechanical limit is the ø6 mm blind-hollow shaft. Shaft insertion depth, clamp force, static misalignment, dynamic misalignment, axial cable bend radius, and cable strain must be controlled. A forced bore fit, weak clamp, or housing movement can create bearing load, repeatability drift, or intermittent feedback faults under vibration.

Wiring & Installation

Before replacement, record the axial cable wiring for Bit 1–13, Latch, DIR, power supply, GND, and shield. Confirm that the controller reads binary code directly, and verify whether the latch input is fixed, pulsed, or synchronized with the controller scan cycle.

During installation, confirm the ø6 mm blind-hollow fit without forcing the shaft. Keep the encoder body square to the mounting face, control clamp preload, route the axial cable away from inverter and motor power wiring, and keep the cable bend radius within the installed routing space. Maintain shield continuity into the cabinet and avoid ground loops between the encoder housing, machine frame, and controller earth. After startup, verify zero/reference value, counting direction, bit transition stability, latch response, and repeatability over several machine cycles.

Custom Compatible Solution

EncoderWorks can configure the replacement around the installed controller and mechanical interface:

• Match 13-bit singleturn parallel binary position output and push-pull driver behavior
• Preserve Bit 1–13 mapping, latch input timing, DIR logic, supply range, and controller input compatibility
• Adapt the ø58 mm blind-hollow flange, ø6 mm blind-hollow shaft, clamp interface, and axial 1 m cable layout
• Review cable shielding, grounding, EMC routing, binary decoding, input threshold, shaft fit, clamp preload, and cable bend radius
