Explore our core engineering line-up, featuring spring-loaded contacts, high-speed magnetic data links, and multi-pin custom power solutions.
Modern electrical engineering requires interfaces that combine convenience, longevity, and high-capacity electrical performance. Traditional mechanical plug-and-play interfaces are prone to socket wear, dust ingress, and connection degradation under vibration. High-current magnetic connectors offer a reliable solution by using magnetic attraction forces to ensure consistent electrical contact.
By integrating customized pogo pin (spring-loaded contact) architectures with high-grade permanent magnets (such as Neodymium Iron Boron, or NdFeB), these components facilitate zero-force blind mating while conducting continuous currents ranging from 5A to over 40A. Our focus centers on reducing contact resistance and mitigating heat generation ($I^2R$ losses) to prevent thermal degradation in heavy-duty electronic systems.

Why Tier-1 global technology brands rely on our Shenzhen-based production facilities for high-current components.
Situated in Songgang, Shenzhen, our facility accesses a comprehensive supply chain. From raw alloy suppliers to advanced electroplating and surface treatment facilities, our turnaround times for prototypes and mass production remain competitive.
We utilize precision high-speed CNC turning lathes, automated spring-winding machines, and custom-designed assembly lines. These technologies minimize human error and ensure consistency across large production runs.
Our quality verification processes leverage automated optical inspection (AOI), dynamic contact resistance meters, spring force testers, and salt spray chambers. This guarantees 100% compliance before shipment.
Analyzing key advancements in materials science, thermal dissipation, and electrical routing design.
As applications in New Energy Vehicles (NEVs), Automated Guided Vehicles (AGVs), wearable technology, and medical hardware mature, the requirements for interconnect systems have shifted. Current densities are rising while physical footprints shrink. These changes present several key engineering challenges:
| Electrical & Mechanical Parameters | Standard Specification Range | High-Current Specialization Limit | Testing Methods & Compliance |
|---|---|---|---|
| Rated Current (Continuous) | 1A – 5A per pin | Up to 40A per pin (Custom Coaxial Design) | UL 1977 Temperature Rise Test (< 30°C rise) |
| Contact Resistance | < 30 mΩ | < 10 mΩ (Bias-cut plunger structures) | EIA-364-23 Low Level Contact Resistance |
| Mating Cycles (Durability) | 10,000 to 50,000 cycles | Up to 500,000 cycles | EIA-364-09 Mechanical Cycle Testing |
| Spring Force per Pin | 50g – 150g | Up to 500g (Optimized for vibration) | Internal force-displacement gauge verification |
| Waterproof Protection | IPX5 / IPX6 | IP67 / IP68 (LSR overmolded housings) | IEC 60529 Ingress Protection Standard |
