Key Features & Advantage:

Robust 4.0mm Pitch Design: The 4.0mm spacing effectively increases the creepage distance and clearance between pins, preventing electrical arcing in automotive power and high-voltage signal networks.
Extreme Automotive Durability: Engineered to deliver zero-compromise mechanical and electrical connection stability within a wide operating temperature from -40°C to +105°C.
Engineered Stepped Pin Profile: Features a unique tailored pin profile 1.20mm base tapering to 0.60mm terminal tips) to ensure perfect mechanical guidance and precise mating with female receptors.
Premium Thermal Plastic Options: Molded with premium UL 94V-0 certified Polyester, NL6T, or liquid crystal polymer (LCP) to easily survive waves or high-temperature industrial reflow soldering lines.
Flexible Custom Configuration: Fully adaptable to your engineering blueprint with customizable plating options (Gold Flash, 3U" Gold, Matte/Bright Tin) and automated assembly packaging options (Tape & Reel, Tube, Tray).
