Explore our precision manufacturing line of standard spring loaded pins, multi-pin waterproof sockets, and customized magnetic self-aligning charging cable assemblies.
Founded in February 2011 in Songgang Street, Shenzhen, within the heart of the Guangdong-Hong Kong-Macao Greater Bay Area, our enterprise has established itself as an innovative force in high-reliability connection systems.
We specialize in the research and development, design, and manufacturing of high-performance POGO PIN (spring-loaded probe contacts) and specialized Magnetic Connectors. Through continuous process optimization and technology accumulation, we have evolved into a major supplier for leading hardware manufacturers globally.
Our operation is certified to the ISO9001:2015 International Quality Management System. With a strong quality control infrastructure and a rigorous environmental compliance system, we deliver products engineered to meet demanding industrial and commercial requirements.
We work directly with OEM engineering teams to develop bespoke magnetic connector geometries, customized polarity counts, magnetic forces (N35 to N52 ratings), and specialized current profiles ranging from milliamperes up to 30 Amps.
Our pins utilize advanced electroplating processes, applying up to 50 micro-inches of precious gold (Au) over nickel (Ni) diffusion barriers. This ensures low contact resistance, excellent wear characteristics, and superior corrosion resistance.
Magnetic mating prevents mechanical misalignment and terminal damage. In the event of a sudden cable strain, the magnetic interface breaks away safely, protecting host boards and internal electronics from mechanical damage.
As industrial systems demand higher data speeds and smaller form factors, our engineering division is developing key innovations in magnetic self-mating technologies:
Modern product architectures demand combined power and high-speed data capabilities. Traditional mechanical connectors require high insertion forces and are prone to pin wear. Our development team is pioneering impedance-matched magnetic interfaces capable of supporting USB 3.1 Gen 2 and Type-C alternate mode protocols, delivering up to 10 Gbps and 100W PD charging over a simplified magnetic connection interface.
For medical devices, smart wearables, and industrial handheld terminals, environmental ingress protection is critical. By combining custom-formulated liquid silicone rubber (LSR) overmolding with high-pressure epoxy potting techniques, we engineer custom magnetic connectors that withstand deep submersion (IPX8) and high-pressure steam cleaning (IPX9K) without compromising signal integrity.
Our spring-loaded magnetic connector systems serve a wide variety of hardware sectors. By developing application-specific housings and magnetic pairings, we resolve design challenges across industries:
Providing compact charging rings and pins for smartwatches, fitness trackers, and Bluetooth headsets (e.g., QCY, HAYLOU). Features thin profile structures, biocompatible gold alloy plating, and sweat/corrosion resistance.
Providing high-reliability signal pin and custom power connection systems for vehicle sensors, camera modules, battery management systems (BMS), and automated subassembly charging interfaces.
Utilized in patient monitoring systems, modular surgical tools, and hearing aids. Quick-release magnetic breakaway prevents hazard trip risks and simplifies sanitization procedures.
Robust docking interfaces for automated guided vehicles (AGVs), robotic end-effectors, and test fixtures. Supports blind-mating, high-cycle durability (100,000+ matings), and high vibrational stability.
Smart home security terminals, learning tablets, and digital cameras. Magnetic docking bays enable effortless tool-less mounting and stable power/data connection.

Operating out of our specialized Shenzhen facility, Rongqiangbin integrates vertical manufacturing workflows. By executing lathe production, stamping, assembly, and quality verification in-house, we control lead times and maintain cost competitiveness.
Our CNC high-precision Swiss-type lathes machine plungers and barrels down to ±0.005mm tolerances, ensuring dimensional accuracy.
Specialized electroplating processes establish uniform gold layers, enhancing anti-oxidation and electrical performance.
Custom-built assembly systems feed springs, plungers, and barrels, achieving high output while minimizing defects.
Every production run undergoes CCD optical inspection and automated electrical testing for resistance and continuity.
For international buyers managing complex supply chains, we provide technical documentation and support through our designated export units. We ensure our components align with global regulatory frameworks:
When selecting a magnetic connector manufacturer for custom applications, engineering and procurement teams should consider the following variables:
Ensure the supplier matches the gold alloy thickness to the mechanical wear profile of the application. Smartwatches often require thicker plating or anti-corrosion barriers (e.g., Pd-Ni) to resist human sweat erosion.
Evaluate magnets to ensure keying geometry prevents inverse polarity matching, which could damage internal circuits.
Specify the spring material (e.g., Music Wire or Stainless Steel for general use; Beryllium Copper for high temperature/high current conductivity) to ensure stable spring force throughout the target lifecycle.
Examine our specialized high-current pins, custom bending type spring contacts, and waterproof charging adapters engineered for robust industrial performance.
