Precision-engineered hardware customized to meet international OEM manufacturing standards.
In the rapidly changing consumer electronics and industrial IoT environment, cable management has shifted from a matter of convenience to an essential aspect of hardware design. The emergence of the Supercalla magnetic self-coiling mechanism has addressed a significant market need: cable clutter, wear-and-tear at junction points, and spatial inefficiencies. For procurement teams, system integrators, and consumer electronic brands, sourcing reliable OEM Supercalla cables requires a deep understanding of magnetics, materials science, and reliable connector design.
Globally, industrial automation, medical diagnostics, smart retail, and defense systems are adopting magnetic coupling mechanisms. Traditional cable designs are prone to high mechanical failures caused by frequent bending and pulling. The integrated neodymium magnetic ring alignment used in OEM Supercalla designs distributes mechanical stress evenly, extending cable service life. Additionally, incorporating custom spring-loaded pogo pins into these magnetic structures ensures stable electrical connectivity even under vibration or continuous rotation.
Our design methodology prioritizes signal integrity, magnetic flux density, and long-term durability.
Utilizing high-coercivity N52 Neodymium permanent magnets. The alternating polarity (North-South) configuration is optimized to maximize magnetic hold while avoiding interference with the high-speed data transmission lines inside the shielding jacket.
Spring-loaded contact designs featuring high-purity brass plungers with gold plating (up to 30u"). Designed for up to 100,000 mating cycles, maintaining low contact resistance (<30mΩ) under high mechanical vibration.
Outer jackets extruded using food-grade liquid silicone rubber (LSR) or highly elastic TPU. Resistant to oil, sweat, and UV, providing excellent flexibility and flame retardancy (UL94 V-0 standard).

Established in February 2011 in Songgang, Shenzhen—the core of the Guangdong-Hong Kong-Macao Greater Bay Area—our company has grown into a leading manufacturer of POGO PIN connectors and customized magnetic USB charging cable assemblies. With over a decade of dedication, we have established a complete vertically integrated manufacturing process, from precision mold design and automated lathe turning to automated connector assembly and strict quality assurance.
"Customer first, integrity first" is the core principle that guides our team of engineers and technicians. Our production processes conform to the ISO9001:2015 International Quality Management System certification, ensuring that every project, from custom high-current automotive contacts to medical-grade magnetic charging interfaces, is manufactured under strict quality control.
Our strategic partnerships include Honeywell, Samsung, SIEMENS AG, ZTE, 360, QCY, HAYLOU, Shanghai Laimu, Luxshare Group, Aoni Electronics, and Amphenol Group. These companies rely on RQB for critical connection components that require high performance and reliability.
Deploying high-performance magnetic assemblies across diverse operational landscapes.
Our high-current custom pins and charging connectors are used in battery management systems (BMS), in-vehicle entertainment units, and autonomous sensors. These components are designed to withstand high vibrations and thermal extremes.
For devices like smartwatches, Bluetooth earbuds, and AR smart glasses, our low-profile, corrosion-resistant SMT/SMD pogo pins enable thin product profiles and reliable IP67/IP68 waterproof charging connections.
In logistics warehouses, smart factories, and medical monitoring systems, magnetic couplings prevent accidental damage to equipment. If a cable is pulled unexpectedly, it detaches safely without damaging the device port.
Maintaining strict product quality through rigorous inspection protocols and international compliance standards.
At Shenzhen Rongqiangbin, quality control is integrated into every phase of production. We operate state-of-the-art testing equipment including:
Our products comply with RoHS, REACH, and California Proposition 65 standards. This makes them suitable for direct export and integration into electronic products destined for North American, European, and Asia-Pacific markets.
Our factory operates under ISO9001:2015 standards, ensuring batch-to-batch consistency and complete traceability from raw copper wire to finished, packed magnetic cables.
Our engineering team is continuously working on innovations to support the future of magnetic connection technology.
Optimizing micro-pitch (0.8mm) pogo pins to reduce board space, while supporting 3.0A currents for wearable charging interfaces.
Developing self-coiling magnetic configurations capable of supporting USB Power Delivery EPR (48V/5A), with integrated short-circuit protection.
Transitioning to plant-based elastomers and allergen-free, nickel-free plating formulas designed specifically for medical and skin-contact devices.
Providing engineering insights and clear commercial answers to facilitate strategic procurement decisions.
Engineered components designed for high-density, reliable electrical connections.
