Cable Performance & Design

• 5-meter length is ideal for applications requiring greater distance between motor and drive.
• Engineered for SIN/COS (1 Vpp) and resolver analog signals requiring high signal integrity.
• Dual-layer shielding provides excellent EMI/RFI protection in noisy industrial environments.
• Low capacitance design minimizes signal distortion over the extended 5-meter length.
• Impedance-matched pairs (120 Ω) ensure minimal signal reflections for accurate feedback.
• PVC jacket offers good durability and resistance to common industrial contaminants.

Installation & Compatibility

• Compatible with Allen-Bradley drives supporting SIN/COS or resolver feedback interfaces.
• Connect the SpeedTec DIN connector securely to the motor's encoder port.
• Terminate the flying leads to the drive's feedback input terminals using proper ferrules.
• Maintain minimum bend radius of 85mm during installation to prevent cable damage.
• Ground the cable shield at the drive end only to prevent ground loop interference.
• Route separately from power cables and keep at least 150mm away from high-voltage lines.

Packaging & Shipping Details

• Cable is supplied coiled on a reel with protective wrapping.
• Each unit includes the 5-meter cable with pre-attached SpeedTec DIN connector.
• Shipped internationally via FedEx, UPS, DHL with tracking provided.
• Standard packaging ensures protection during transit.

Frequently Asked Questions

• What is the maximum recommended cable length for SIN/COS signals? For optimal performance, lengths up to 10m are typical; this 5m cable is well within that range.
• Can this cable be used in continuous flex applications? No, it is a standard non-flex cable designed for fixed installations.
• How do I ensure proper shield termination? Use a shielded cable gland or clamp that provides 360-degree contact at the drive enclosure entry point.
• Is this cable suitable for outdoor use? The standard PVC jacket is for indoor use; for outdoor applications, consult specifications for rated alternatives.
• What tools are needed for termination? Wire strippers, ferrules, a crimping tool, and possibly a shield termination tool are recommended.
