Description
The Omron R88A-CR1A005S is a 5-meter standard servo motor power cable (also called main circuit / encoder + brake combo cable depending on series) for Omron G-series (G5, G3) and select R88A-compatible AC servo motors/drives. It connects the servo drive’s power output terminals to the servo motor’s U/V/W / Brake / Thermistor pins. Related part numbers — R88A-CA1A003S (3 m), R88A-CA1A005S (5 m), R88A-CA1A010BF (10 m, BF = shielded flexible), R88A-CR1B010BN (10 m power/encoder combo for specific R88A-CR series) — cover various lengths and shielding grades (standard / flex / oil-resistant) for G5/G3 servo systems.
These are pre-molded OEM cables with correct pinout for Omron servo motor connectors (circular metal connector on motor body + drive-end terminal block or Harting), ensuring proper shielding continuity for EMI suppression and reliable power delivery to the servo windings and brake circuit.
Key Features
- Compatibility: Omron G5 Series Servo (R88M-□-G□) and G3 Series (R88M-□-G3□) — verify motor frame size (connector type A/B/C on motor).
- Length Options: 3 m (CA1A003S), 5 m (CR1A005S / CA1A005S), 10 m (CA1A010BF / CR1B010BN).
- Shielding: Overall braided shield (S suffix = standard PVC; BF = bend-flex oil-resistant outer jacket for drag chains).
- Included Circuits: Power (U/V/W), Brake (if motor has brake option — check motor suffix), Motor Thermistor (PTC), sometimes combined with encoder in CR1B/CA1A “combo” cables — verify if your cable is power-only or power+encoder.
- Connector Type: Molded circular plug mates with servo motor’s power connector; opposite end terminates to drive power terminals (screw / Harting depending on drive model R88D-□-G□).
- Country of Origin: Japan / China (Omron Global)
Model & Length Reference Table
Model | Length | Cable Type | Shielding/Flex | Typical Use |
|---|---|---|---|---|
R88A-CA1A003S | 3 m | Power (+Brake/Thermistor) | Std. PVC shield | Short-run G5/G3 servo |
R88A-CA1A005S / CR1A005S | 5 m | Power (+Brake/Thermistor) | Std. PVC shield | Most common length |
R88A-CA1A010BF | 10 m | Power (+Br/Th) | Flex-Bend (BF) oil-resist. | Drag-chain / longer run |
R88A-CR1B010BN | 10 m | Power+Encoder Combo* | Flex / Oil-resist. (N-suffix) | Where single combo cable preferred |
Some CR1B cables combine power + encoder in one sheath — confirm your servo motor has the appropriate dual-connector or single-combo interface. G5 typically uses separate power & encoder cables; combo cables are more common on G3 or specific R88A kits.
⚠️ Critical Checks Before Ordering:
Technical Specifications (Representative — R88A-CR1A005S / CA1A005S, 5 m Power Cable for G5 Servo)
Parameter | Specification |
|---|---|
Model / Order Code | R88A-CR1A005S ≈ CA1A005S (Omron G-series Servo Accessory) |
Cable Function | Servo Motor Power + Brake + Thermistor (PTC) — Encoder separate on G5 |
Compatible Motors | Omron G5 Series (R88M-…-G…) — confirm connector type (A/B/C per frame size) |
Compatible Drives | Omron G5 Drives (R88D-…-G…) — terminates to power screw terminals |
Length | 5 m (CA1A005S / CR1A005S) |
Conductor / Shield | Tinned copper, overall braid shield (connected to motor case & drive PE) |
Rated Voltage/Current | Matches servo motor rating — typically 250 V AC / up to motor rated current (e.g., 2.5 A for 200W, 12 A for 1.5 kW etc.) |
Brake Leads | Included (2 wires — +Brake & -Brake referenced to 24V external supply or drive brake output) |
Thermistor (PTC) Leads | Included (2–3 wires — PTC sense to drive for motor overtemperature) |
Outer Jacket | Gray PVC (S suffix = standard); BF = oil-resist. polyurethane for flex chains |
Min. Bend Radius | ≈ 10 × cable OD (standard); ≈ 7 × OD (BF flex type) |
Operating Temp. | -20 … +70 °C (static); -20 … +60 °C (flexing — BF type) |
Standards | CE (shielded cable), UL AWM style (where applicable), RoHS |
