Product Overview

The Sinyinda SYCBCHY8P2D6XF is a 2+6 composite power and signal socket female connector (copper-gold plated version) specifically designed for high-reliability interconnection at the panel end in the 100-ampere class. This product features a rated current of up to 120A per pin and integrates 6 channels of 3A signal circuits for safety coordination functions such as HVIL, temperature monitoring, and communication feedback, achieving "high-power drive + critical status monitoring" integrated into a single panel port. It adopts high-specification copper-gold plated (1u) contact technology, which offers superior anti-sulfidation, salt spray resistance, and signal loop compatibility compared to silver-plated solutions, making it especially suitable for harsh environments such as sealed high-temperature energy storage cabinets and high-salt-spray marine applications. Rated voltage is DC 1000V, operating temperature ranges from -40°C to +125°C, the four-corner M4 screw locking mechanism provides a pull-out force of ≥200N, and the recommended insertion/withdrawal life is 500 cycles. It is particularly suited for scenarios with rigid requirements for "120A panel-level reliable interconnection + 6-channel safety signal synchronization + long-term oxidation resistance," such as energy storage PCS DC busbar interfaces, charging pile cabinet internal connection ports, photovoltaic combiner box output terminals, and special vehicle power distribution panels, and pairs precisely with the male connector SYCBCHY8P2D6XM to form a complete 100-ampere-class heavy-duty interconnection solution.

Core Advantages Exclusive to the Panel End (Copper-Gold Plated Version)

• Copper-Gold Plated (1u) Contact Technology:Compared to the silver-plated version in the same series, the gold plating layer is extremely stable in chemical properties, with anti-sulfidation capability of >1000h (H₂S test) and salt spray corrosion resistance of >720h (5% NaCl), completely solving the contact oxidation failure issues caused by sulfur-containing gases inside energy storage cabinets and salt spray in marine engine rooms; additionally, the gold layer has moderate hardness, resulting in a lower friction coefficient when mated with silver-plated male pins, reducing insertion/withdrawal wear by 40%.
• 120A Terminal PCB Soldering/Screw Dual-Mode Installation:The main circuit terminal supports two installation methods: ① PCB through-hole soldering (pad diameter Φ6mm, wave soldering temperature resistance 260°C/10s); ② M6 screw direct locking of copper busbar (torque 3.5±0.3N·m). Users can flexibly choose based on panel structure; the soldering mode is suitable for compact PCS modules, while the screw mode is suitable for direct connection of large cross-section copper busbars.
• Integrated Heat Dissipation Path Design:Four heat dissipation rib grooves are added at the bottom of the female housing, directly contacting the equipment panel/heat sink. At 120A full load, heat dissipation through the panel can reduce terminal temperature rise by 15K; the PA6T insulating substrate has a thermal conductivity of 0.3W/m·K, 50% higher than ordinary PA66, preventing heat accumulation from causing substrate creep.
• 6 signal terminals with independent shielding:A metal shielding cover is built into the signal area, providing both physical isolation and electromagnetic shielding from the main circuit terminals. At 120A full load, EMI suppression in the signal area exceeds 45dB, ensuring critical signals such as HVIL and CAN communication are not disturbed by power noise; the signal terminals use a copper-gold plating (0.5u) process, consistent with the main circuit material system, avoiding electrochemical corrosion between dissimilar metals.
• M4 screw mechanical locking mechanism:Four-corner M4 stainless steel screws combined with anti-loosening spring washers, with a locking torque of 1.2±0.1N·m and a pull-out resistance of ≥200N, passing a 20G random vibration test (4h/axis), preventing accidental detachment caused by equipment vibration or cable self-weight; the screw holes are countersunk, leaving a flat surface without protrusions after installation.
• -40℃~+125℃ wide temperature adaptability:PA6T insulating substrate + FKM sealing ring, no brittle cracking at -40°C low temperature, no creep at 125°C high temperature, meeting the needs of extreme temperature difference environments such as outdoor energy storage, marine engine rooms, and desert photovoltaic power stations; the sealing ring has a compression permanent deformation rate of <15%, maintaining IP67 protection rating during long-term use.
