Product Overview

The Sinyinda SYCBCHY8P2D6XM is a 2+6 composite power and signal plug male specifically designed for hundred-amp heavy-duty power transmission scenarios. This product breaks through the current-carrying limit of conventional composite connectors, with a single-pin rated current of up to 120A, while integrating 6 channels of 3A signal circuits for safety coordination functions such as temperature monitoring, high-voltage interlock (HVIL), and communication feedback, achieving "high-power drive + critical status monitoring" in a single-port integration. Rated voltage DC 1000V, operating temperature -40°C to +125°C, copper silver-plated (3u) contacts ensure low contact resistance and excellent heat dissipation under continuous 120A current-carrying conditions, the four-corner M4 screw locking mechanism provides ≥200N pull-out resistance, with a recommended insertion/withdrawal life of 500 cycles. It is particularly suited for extreme operating conditions with stringent requirements for "120A continuous current-carrying + 6-channel safety signal coordination," such as energy storage battery cluster parallel busbars, electric forklift/AGV fast-charging interfaces, photovoltaic inverter DC inputs, and ship shore power connections, precisely mating with the female socket SYCBCHY8P2D6XF to form a complete hundred-amp heavy-duty interconnection solution.

Core Advantages Exclusive to Heavy-Duty Cable Ends

• 120A Terminal Hydraulic Cold-Pressing Process:The main circuit terminal adopts a T2 copper forged structure, crimped with a dedicated 16mm² hydraulic crimping tool (model SYC-H120), with a crimping area of ≥16mm², pull-out force of ≥300N, contact resistance of ≤1mΩ, and terminal temperature rise of <35K at full 120A load, avoiding the loose connection heating and arc risks caused by traditional crimping.
• Copper Gold-Plated (1u) High-Conductivity Contacts:Compared to silver-plating, the gold-plating layer thickness is increased to 1μm, with improved conductivity and 3 times enhanced arc erosion resistance, particularly suitable for frequent on-off conditions in 120A/1000V DC systems, with no obvious arcing marks when breaking at 1000V.
• Power-Signal Dual Isolation Structure:The housing features a built-in ceramic thermal barrier plus metal shielding cover, providing both physical isolation and electromagnetic shielding between the 120A power zone and the 6-channel signal zone. At full 120A load, the signal zone temperature rise is <8°C, with EMI suppression of >40dB, ensuring HVIL and temperature sampling signals are not interfered with by power noise.
• M4 screw mechanical locking mechanism:Four-corner M4 stainless steel screws with anti-loosening spring washers, locking torque 1.2±0.1N·m, pull-out resistance ≥200N, passes 20G random vibration test (4h/axis), preventing accidental disconnection of heavy-duty cables due to self-weight or vibration.
• -40℃~+125℃ wide temperature adaptability:PA6T insulating substrate + fluororubber sealing ring, no brittle cracking at low temperature -40℃, no creep at high temperature 125℃, meeting the requirements of extreme temperature difference environments such as outdoor energy storage and marine engine rooms.
• Heavy-duty plugging cycle life guarantee:After 500 plugging cycles at 120A current, contact resistance change rate <15%, silver plating wear <0.3μm, meeting high-frequency heavy-duty usage scenarios such as annual maintenance of energy storage systems and daily charging of forklifts.
