Key Features & Advantage

Vertical Straight Dip Design: Ideal for standard vertical board-to-board stacking, delivering stable signal and power transmission between perpendicular or parallel PCBs.
Multiple Profile Heights Available: Offers three plastic body heights (H=5.0mm, 7.1mm, 8.5mm) via HFNSS50, HFNSS71, and HFNSS85 series to match various PCB stacking clearance requirements.
Premium Material Options: Built with high-performance Nylon-6T (NL6T) or Liquid Crystal Polymer (LCP) insulators, supporting up to 260°C reflow and wave soldering processes.
Phosphor Bronze Contacts: Uses high-elasticity phosphor bronze or brass contact materials to ensure low contact resistance and durable mating cycles.
Flexible Plating & Configuration: Supports 2 to 40 pins per row, with Gold Flash, Gold 3U", or Tin plating options to meet different budget and anti-oxidation demands.
Eco-Friendly Compliance: Fully RoHS & REACH compliant; halogen-free material options are available for green electronics designs.
