Highly durable interface units designed for seamless board-to-board testing and heavy-duty industrial charging configurations.
Exploring the strategic demand for high-reliability spring probes in Scandinavia's extreme environments.
Norway is a global leader in ocean-based industries, offshore energy, and carbon-neutral technologies. The electrification of the maritime sector—ranging from hybrid battery ferries to deep-sea seismic mapping systems—requires electronic connections that can survive extreme mechanical stress, vibration, salt mist, and pressure variations. In Stavanger, Bergen, and Oslo, R&D teams are shifting away from traditional soldered connectors toward robust double head type pogo pins.
A double-head pogo pin features plungers on both sides, allowing for a solderless, purely elastic mechanical connection between two co-planar or parallel printed circuit boards (PCBs). This unique capability facilitates blind mating, modular swap-outs, and reduces physical stress on delicate solder points. For underwater sensor pods and subsea telemetry devices, which require hermetically sealed outer casings, the dual-action mechanical resilience of double-ended pogo contacts offers unmatched design flexibility.
As Norway leads the world in electric vehicle (EV) adoption and pioneering zero-emission commercial ships, the infrastructure requirements are evolving rapidly. Heavy-duty applications need specialized battery management systems (BMS) where boards are stacked vertically. Double-head type connectors serve as the ideal interface between cell-monitoring systems and energy-dense modules. By implementing our high-current double-headed pins, operators can ensure sustained, reliable electrical paths without risking joint failure under constant vehicular or maritime vibration.
Engineered to support critical projects from research labs to mass-scale industrial deployments.
An engineering analysis of material composition, durability metrics, and electrical integrity.
We source ultra-resilient Beryllium Copper (BeCu) and high-leaded Brass (C3604) for plungers to achieve optimal conductivity. Gold plating ranges from 3u" to 30u" to resist aggressive saline corrosion in marine zones.
Standard spring pins typically support 1A-2A. Our customized double-head probes leverage internal ball structures or bias-cut designs to carry currents up to 30A continuously, perfect for power-delivery modules.
Equipped with corrosion-resistant SUS304 springs, our assemblies endure up to 1,000,000 mating cycles in lab testing. They prevent signal drops during heavy wave motions or high-impact robotic tasks.
Traditional PCB connectors require mechanical soldering to at least one interface surface. In high-density assemblies where vertical space is constrained, standard soldering leads to elevated thermal gradients and premature stress cracks under temperature variations. Double-head pins resolve this by making elastic pressure contact on both ends. This solderless layout accommodates mechanical tolerances and board warping, significantly simplifying design complexity and assembly speeds.

Mapping physical board requirements to high-precision engineering environments.
Since the establishment of our company, our focus has been "excellent quality, intimate service" and our core value is "customer-centric, create more value for customers." This philosophy drives our development in highly demanding markets:
Double-head type connectors bypass the standard limits of rigid connector pins. By compressing smoothly on both ends, they absorb mechanical deviations during thermal expansion, protecting critical board components from structural cracks in offshore or subsea deployments.
Answers to complex design questions for mechanical and electrical engineers.
Double-head type pogo pins have plungers on both sides, allowing for a solder-free interface on both PCBs. This is essential for structural assemblies that require quick disassembly, modular swapouts, or where high thermal cycling makes standard solder joints prone to fatigue cracking. This floating contact design successfully isolates vibration and reduces mechanical stress.
For maritime, subsea, and coastal offshore projects, we offer high-grade electroplating options, including up to 30 micro-inches of gold over nickel layers. Additionally, we utilize stainless steel (SUS304 or SUS316) for inner springs to ensure the connector remains highly resistant to oxidation and corrosion under heavy salt spray conditions.
While normal signal pins carry 1A to 2A, our custom high-current double-headed models are built with a bias-cut plunger or internal ball structure. This enables reliable operation at currents up to 30A. This high performance is critical for electric vehicle battery packs, solar inverter modules, and offshore telemetry charging interfaces.
Shenzhen Rongqiangbin is certified to the international ISO9001:2015 Quality Management Standard. Our raw materials and products comply fully with environmental requirements, including RoHS and REACH directives, ensuring smooth customs approval and complete environmental compliance for European markets.
