Cable Performance & Design

• Specifically engineered for high-resolution SIN/COS and resolver encoder signals.
• Dual-layer shielding (foil + braid) provides superior EMI/RFI protection for sensitive analog signals.
• Matched impedance (120Ω) and low crosstalk ensure signal integrity for precise positioning.
• 1-meter standard length is ideal for short, fixed connections between motor and drive.
• SpeedTec DIN connector offers a secure, vibration-resistant motor interface.
• Flying-lead drive end allows for direct termination to drive terminal blocks.

Installation & Compatibility

• Compatible with Allen-Bradley drives supporting SIN/COS or resolver feedback.
• Match the SpeedTec DIN connector to the high-resolution encoder port on the motor.
• Keep cable runs as short as possible; avoid coiling excess length to prevent noise coupling.
• Properly ground the shielding at the drive end only to avoid ground loops.
• Route away from power cables, motor leads, and sources of electromagnetic interference.
• The non-flex design is for fixed installations; do not use in continuous flexing applications.

Packaging & Quality Assurance

• Cable shipped in a sealed polybag with part number label for identification.
• Each cable is tested for continuity, insulation resistance (>100 MΩ), and shield integrity.
• International shipping via FedEx, UPS, DHL with full tracking.
• Standard packaging includes the single 1-meter cable unit.

Technical FAQs

• What encoder types does this cable support? It is designed for SIN/COS high-resolution and resolver-type encoders.
• Can this cable be used for incremental encoders? It is not recommended; use a dedicated incremental encoder cable.
• Why is impedance matching important? 120Ω impedance matching minimizes signal reflections for accurate analog feedback.
• Is this cable suitable for dynamic flexing? No, it is a standard non-flex cable for fixed installations.
• What is the purpose of the dual shielding? Foil and braid shielding protect low-level analog signals from electrical noise.
