Description
Double head spring loaded contacts for Flexible Board-to-Board Connections
Double head spring loaded contacts engineered by CTP provide hardware developers with exceptional versatility for complex board-to-board applications. This innovative double-head design offers engineers more choices for highly flexible space adjustment, ensuring a reliable and continuous interface even in the most compact electronic assemblies.
As a specialized double head pogo pin, the basic structure consists of a precision-turned barrel, a high-performance cutting plunger, and a robust compression spring. The carefully crimped barrel tube mouth edge securely retains the plunger, while the internal spring mechanism delivers a calibrated contact force. This guarantees ultra-stable electrical connections between the plunger and the butt joint parts. By integrating this premium interface pogo pin, your designs achieve unmatched mechanical reliability and secure power transmission.
Key Engineering Advantages:
- Flexible Space Adjustment: The ultimate spring loaded contact solution for resolving strict spatial constraints in high-density B2B connections.
- Premium Plating: Precision gold-over-nickel plating (0.25μm Au on plunger) ensures superior conductivity and corrosion resistance.
- Exceptional Durability: Rigorously tested spring loaded pins proven to withstand 20,000 mating cycles with a consistent 90g contact force.
- Stable Electrical Performance: Delivers a steady DC 12V / 1A output with ultra-low contact resistance (≤50 mΩ).
