Product Overview:
The CR10661 is a Kollmorgen-manufactured encoder cable assembly designed for connecting servo motors (AKM, S-Series, B-Series) to AKD/AKM servo drives. The cable is optimized for high-frequency encoder signals (EnDat 2.2, BiSS-C, Hiperface) with superior EMI shielding.
Key Technical Specifications:
| Parameter | Value |
|---|---|
| Cable Type | Shielded twisted pair + power pair |
| Connector A (Motor End) | M23, 12-pin, straight, male |
| Connector B (Drive End) | M23, 12-pin, straight, female |
| Cable Length | 6 m (standard for CR10661) |
| Conductor Gauge | 28 AWG (signal), 20 AWG (power) |
| Shielding | Double-shielded: foil + braided copper (≥85% coverage) |
| Shield Continuity | ≤5 mΩ end-to-end |
| Insulation Resistance | ≥100 MΩ at 500 VDC |
| Dielectric Strength | 500 VAC, 1 minute, no breakdown |
| Operating Temperature | -20°C to +80°C (flexing), -40°C to +105°C (static) |
| Bend Radius (min) | 5× cable diameter (static), 10× cable diameter (dynamic) |
| Jacket Material | PUR (Polyurethane) — oil and abrasion resistant |
| Color | Gray (standard) |
| Weight | ~0.18 kg |
| Certifications | CE, UL, cUL, RoHS, REACH |
Functional Features:
- Double shielding — eliminates EMI from VFDs and servo drives
- PUR jacket — resistant to oils, coolants, and abrasion
- Gold-plated contacts — corrosion-resistant, low contact resistance
- Drain wire — for shield grounding at drive end
- Pre-tested — 100% continuity and insulation tested at factory
Applicable Industries:
All Kollmorgen servo motor/drive applications requiring encoder feedback
Installation Requirements:
- Route cable away from high-current power lines (min 100 mm separation)
- Ground shield at drive end ONLY (single-point grounding)
- Do not exceed minimum bend radius
- Use cable clamp within 150 mm of each connector
Usage Notes:
- Do not cut or modify cable — voids warranty
- Replace immediately if jacket is damaged or shielding is compromised
- Max recommended cable length: 15 m for EnDat 2.2, 10 m for BiSS-C
