Key Features & Advantage

Four-Point Contact System: Utilizes a four-point contact structure to deliver exceptional electrical stability, low contact resistance, and ultimate protection against continuous shock and vibration.
8.50mm Elevated Profile: Designed with an 8.50mm insulator body height, making it ideal for electronic architectures that require specific clearance or extra spacing between PCBs.
Excellent Thermal Stability: Molded with high-temperature-resistant LCP or NL6T materials (UL 94V-0 rated), perfectly matching lead-free wave soldering and reflow processes.
Highly Customizable Options: Offers flexible configurations from 2 to 40 pins per row, multiple surface platings (Gold Flash, 3U" Gold, Tin, Select Plating), and customizable pin lengths.
Eco-Friendly & Reliable: Constructed using high-grade Phosphor Bronze contacts; fully RoHS and REACH compliant, with halogen-free variants available for sustainable designs.
