‌SYP Terminal Wire Power Cable

‌Core Technical Specifications‌

• ‌Terminal Pitch‌: Standard ‌2.54mm‌ ; some variants support ‌2.0mm‌ for compact electronics.
• ‌Pin Diameter‌: Commonly ‌2.8mm‌ or ‌3.5mm‌, matched to wire cross-sectional areas for mechanical stability and reliable electrical contact.
• ‌Rated Voltage‌: Typically ‌250V AC/DC‌, with high-performance variants up to ‌500V‌, suitable for low-voltage power systems.
• ‌Rated Current‌:
  • Standard models: ‌5–10A‌
  • High-temperature/reinforced types: ‌Up to 15A‌ (single core)
  • Multi-core derating: For 4+ cores, current per core must be reduced by >30% to prevent excessive temperature rise.
• ‌Contact Resistance‌: Premium products ≤ ‌10mΩ‌, ensuring low power loss and stable conductivity.
• ‌Insulation Resistance‌: ≥ ‌1000MΩ‌, guaranteeing high-impedance isolation.
• ‌Operating Temperature‌: ‌-25℃ to +85℃‌; industrial-grade variants support ‌-40℃ to +105℃‌.
• ‌Housing Material‌: ‌Nylon 66 (UL94 V-0)‌, heat-resistant, flame-retardant, and impact-resistant.
• ‌Terminal Material‌: ‌C5191 phosphor bronze‌, tin-plated for oxidation resistance and superior conductivity.

• ‌Wire Gauge‌: Commonly ‌28–20 AWG‌ bare or tin-plated copper stranded wire; insulation is ‌UL1007 PVC‌ or ‌silicone‌ (high-temperature resistant).

• 

‌Key Performance Characteristics‌

• ‌Flame Retardancy‌: Certified under ‌UL VW-1‌ and ‌CSA FT1‌ vertical flame tests, compliant with consumer and industrial safety standards.
• ‌Environmental Resistance‌:
  • Resistant to acids, alkalis, oils, moisture, and mold — ideal for humid or industrial environments.
  • Nickel-plated housings offer 3x higher salt spray corrosion resistance, particularly beneficial in coastal regions like Dongguan, Guangdong.
• ‌Mechanical Reliability‌:
  • Features ‌locking mechanism‌ to prevent disconnection under vibration — suited for automotive, robotics, and high-vibration applications.
  • Insertion/removal life ≥ ‌5,000 cycles‌; industrial-grade versions reach ‌10,000 cycles‌.
• ‌Temperature Rise Control‌: ≤ ‌30K‌ at rated current, compliant with ‌IEC 60947-7-1‌.

‌Typical Application Scenarios‌

Note: SYP terminal wires are especially prevalent in LED lighting, commonly used in ‌2-pin plug-in configurations‌. They complement JST, SM, and PH series but dominate in ‌≤4-core, low-power‌ applications due to compactness and cost efficiency.

‌Industry Standards and Certifications‌

• ‌Safety Standards‌: Complies with ‌UL, CSA, IEC 60320‌ series electrical safety norms.
• ‌Environmental Compliance‌: Most products meet ‌RoHS‌ and ‌REACH‌ standards — lead-free and halogen-free.
• ‌Material Certifications‌: Insulation conforms to ‌UL1007‌; conductors follow ‌AWG‌ wire gauge standards.

• ‌Testing Protocols‌: Passes ‌salt spray test (≥48h)‌, ‌constant damp heat (95% RH, 40℃, 96h)‌, and ‌vibration/shock (IEC 60068-2-6)‌ per industrial requirements.

• ‌Selection and Usage Recommendations‌

• ✅ ‌Recommended Use‌: Low-voltage, low-current, frequently mated internal connections (e.g., LED strips, drone batteries).
• ⚠️ ‌Avoidance Guidelines‌:
  • Do ‌not‌ use standard SYP terminals for currents ‌>15A‌ — risk of overheating and terminal melting.
  • In humid environments, prefer ‌nickel-plated housings‌ over zinc-plated.
  • ‌Do not mix‌ with ‌SM or PH‌ series — despite identical 2.54mm pitch, differing lock designs and contact surfaces may cause damage upon forced mating.
