Description
The Omron R88A-CR1A005C is a 5 m standard servo motor encoder cable for Omron G5 / G-series AC servo motors (R88M-□-G□). It connects the servo drive’s encoder interface to the encoder feedback connector on the servo motor — carrying the serial encoder signals (EnDat / Absolute incremental per motor option) for position & speed feedback. Related part numbers:
- R88A-CR1A003C / 010C / 015C / 020C / 030C → Encoder cable in lengths 3 m / 10 m / 15 m / 20 m / 30 m (standard PVC jacket, C suffix).
- R88A-CR1A003CF / 005CF / 015CF / 020CF / 030CF → Flex-grade (F = Flexible / Oil-resistant Polyurethane) for drag-chain / continuous-flex applications — same pinout, tougher outer jacket.
- R88A-CR1A040CF → Extended flex / special length variant (40 m flex — rare; confirm availability).
These are pre-molded OEM cables with the correct miniature circular connector (motor-end) and either a molded connector or terminated wires for the drive-end encoder port (typically RJ45 or Harting on R88D-GP/KN drives; older G3 may use different). G5 series normally uses SEPARATE encoder & power cables — this is the encoder-only cable.
Key Features
- Compatibility: Omron G5 Series Servo Motors (R88M-…-G…) — verify motor frame size (connector type A/B/C on motor body matches cable plug).
- Length Options: 3 m (003C) → 30 m (030C); Flex versions (CF suffix) for drag chains.
- Shielding: Overall braided shield (connected to motor case & drive PE) — essential for noise-free encoder feedback.
- Signal Carried: Serial encoder data (EnDat 2.1/2.2 or 17-bit/20-bit absolute incremental per motor spec), +5 V / GND power to encoder.
- Connector Type: Molded round plug (motor side — size A/B/C per motor frame); Drive side = keyed connector or terminal block (R88D-□-G□ — typically RJ45-type or Harting sub-D — matches servo drive family).
- Country of Origin: Japan / China (Omron Global)
