Cable Performance & Design

• Optimized for SIN/COS (1Vpp) and resolver signals requiring high signal-to-noise ratio.
• Double-layer shielding provides >40dB EMI attenuation from 30MHz to 1GHz.
• Low capacitance (<85pF/m) design preserves signal edge integrity for high-resolution feedback.
• Matched 120Ω impedance minimizes reflections in differential transmission lines.
• 2-meter length offers flexible routing in control panels with moderate distance requirements.
• Precision-twisted pairs reduce crosstalk below -45dB at 1MHz between channels.

Installation & Compatibility

• Designed for Allen-Bradley MP-Series, Kinetix® drives with high-resolution feedback.
• Verify motor compatibility with SpeedTec DIN connector for SIN/COS/resolver interfaces.
• Maintain ≥50mm separation from AC power cables (>600V) and motor power lines.
• Ground shield only at drive end using proper EMI cable clamp or shield termination tool.
• Secure cable with cable ties every 150-200mm; avoid sharp bends below minimum radius.
• Test phase alignment and signal integrity after installation using drive diagnostic tools.

Packaging & Quality Assurance

• Individually packed in anti-static bag with moisture barrier and part number labeling.
• 100% tested for: continuity (≤0.5Ω resistance), hipot (1500V AC/60s), and shield continuity.
• International logistics via FedEx, UPS, DHL with customs documentation support.
• Includes Allen-Bradley publication 2090-IN001 technical reference guide.

Technical FAQs

• What's the difference between this and incremental encoder cables? This cable has impedance-matched pairs and enhanced shielding for analog SIN/COS signals, not digital pulses.
• Can I extend this cable with connectors? Not recommended; extensions may cause impedance mismatch and signal degradation.
• Is this suitable for absolute encoders with EnDat/SSI? No, this is specifically for analog SIN/COS and resolver interfaces.
• What's the maximum recommended length for SIN/COS signals? While this is 2m, for optimal performance, do not exceed 10m without signal conditioning.
• How do I verify proper installation? Check for no signal errors in drive diagnostics and monitor feedback position jitter (<±1 count).
