Key Features & Advantage

Error-Proof Polarizing Key: Molded with a dedicated polarizing slot that aligns perfectly with matching male headers, preventing incorrect insertion and safeguarding delicate circuitry.
Optimized 8.5mm Stacking Clearance: The 8.5mm body height provides the ideal physical clearance needed to bridge horizontal multi-board designs smoothly.
90-Degree Side-Entry Profile: Enables parallel PCB docking to fit thin enclosure form factors and maximize internal air flow or space distribution.
High Pin-Count Capacity: Supports flexible pin configurations up to 80 total contacts, offering maximum capability for multi-channel data and power transfers.
Excellent Thermal Endurance: Optional LCP/NL6T materials allow the housing to withstand aggressive wave and reflow soldering profiles seamlessly.
