Wiring specifications

4-core pin definitions: 1 (black, V -), 2 (white/blue, signal), 3 (red/brown, V+), 4 (green, signal);

Auxiliary power and signal cables need to be wired separately to avoid interference.

Common technical requirements and application scenarios

Certification and Compliance

All components are UL/CSA certified and partially comply with EN standards (such as IP67 protection), meeting industrial environmental safety requirements (such as NEC, IEC 529).

environmental adaptability

Temperature: Most components operate at temperatures ranging from -20 ° C to+70 ° C, while heavy-duty components can operate at temperatures as low as -40 ° C and as high as+105 ° C;

Protection: Outdoor/harsh environment components (such as heavy-duty flat cables, IP67 connectors) support oil resistance, UV resistance, and high-pressure flushing (1200 psi);

Mechanical performance: anti vibration (displacement of 10-500Hz), anti impact (5g), suitable for dynamic scenarios such as machine tools and automated production lines.

Wiring and installation

Conductor connection: IDC (Insulation Displacement Connection) is preferred to reduce wiring errors;

Shielding and grounding: Circular cables contain grounding wires, while flat cables are grounded at one end through cabinet grounding clamps to avoid electromagnetic interference;

Bending radius: All cables must meet a bending radius of "10 times the diameter" to prevent conductor breakage.

Core applications and selection suggestions

Application scenarios

Indoor automation equipment (such as PLC, sensors): Choose KwikLink ™  Lite flat media or thin circular media;

Outdoor/harsh environments (such as automotive production lines, food processing): Choose heavy-duty flat media or coarse circular media (IP67 protection, oil resistance);

High power equipment (such as servo motors): equipped with auxiliary power supply circular dielectric, powered by 16 AWG cable.

Key parameters for selection

Current: Select cables based on device power (such as thin cables for 3A and below, and thick cables for 8A and above);

Protection: Choose IP67 components for humid/dusty environments, and IP20/IP60 for dry environments;

Temperature: For low-temperature environments (such as cold storage), select -40 ° C low temperature resistant components, and for high-temperature environments (such as metallurgy), select+105 ° C high temperature resistant cables.
