Cable Performance & Design

• 90-meter length supports extended-reach applications like large gantries and conveyors.
• Low capacitance design (≤110 pF/m) minimizes signal distortion over long distances.
• Continuous-flex PUR jacket withstands repetitive motion in cable tracks.
• High-density braided shielding (≥85%) provides excellent EMI/RFI protection.
• 7 conductor pairs accommodate standard incremental encoder signal requirements.
• Optimized signal attenuation (<3dB/100m) ensures reliable data transmission.

Installation Guidelines

• Verify compatibility with Allen-Bradley MP-Series drives and incremental encoder motors.
• Use proper strain relief at both connection points for 90-meter cable management.
• When installing in cable carriers, maintain minimum 10x diameter bending radius.
• Ground the shielding at the drive end only to prevent ground loops.
• Route separately from high-voltage power cables (>600V) by at least 200mm.
• Test continuity and insulation resistance (min. 100 MΩ) before commissioning.

Packaging & Quality Assurance

• Cable shipped on industrial reel with protective wrap and moisture barrier.
• Each 90-meter length undergoes 100% continuity and hi-pot testing (1500V AC, 1 min).
• International shipping via FedEx, UPS, DHL with real-time tracking.
• Package includes cable specification sheet and installation guidelines.

Technical FAQs

• What systems is this cable compatible with? Designed for Allen-Bradley MP-Series and 2090-series drives with incremental encoders.
• Can this cable be used outdoors? Not recommended for direct outdoor use unless in protected conduit.
• What is the maximum recommended data frequency? Up to 10 MHz with ≤3dB signal loss over 90 meters.
• How to calculate voltage drop? Approx. 0.15V drop per 100m at 100mA signal current.
• Is field termination of the SpeedTec DIN connector possible? No, this requires factory tooling. Only the flying-lead end is field-terminable.
