Explore our high-performance components precision-engineered for medical devices, consumer wearables, industrial automation, and automotive interfaces.
In high-reliability industrial, medical, and consumer sectors, hardware designs are shifting rapidly towards robust contact interfaces. Magnetic mechanical locking systems offer a zero-force or low-force mating solution that reduces wear and tear, provides breakaway safety, and simplifies the device footprint.
Modern product designs demand sleek profiles with high-frequency charging and rapid data transfer capabilities. Magnetic electrical connectors eliminate alignment challenges by utilizing custom-arranged neodymium (NdFeB) magnets. These systems ensure instant self-guided mating, making them crucial for smart wearables, industrial handheld scanners, and rugged consumer hardware.
For stable current conduction under thermal fluctuation, pogo pins feature C3604 brass barrels with gold or palladium-nickel plating (often 3u" to 50u" gold over nickel). The internal spring, constructed of SUS304 stainless steel or music wire, sustains continuous force (typically 30g to 150g) across up to 100,000 mating cycles without degradation.
Sweat and humidity lead to galvanic corrosion on standard contacts. We offer specialized plating designs alongside liquid silicone molding (LSR) and overmolding techniques to reach IPX7 and IPX8 waterproofing. These configurations are ideal for smartwatches, medical sensors, and demanding outdoor telemetry systems.
Founded in February 2011 and situated in Songgang Street, Shenzhen, within the highly integrated Guangdong-Hong Kong-Macao Greater Bay Area, our company focuses on the comprehensive development, manufacturing, and QA verification of precision Pogo Pin connectors and magnetic interfaces. Through continuous optimization and research, Shenzhen Rongqiangbin (RQB) has emerged as a premier manufacturer in the interconnect industry.
Operating under the fundamental principles of "customer first, integrity first," we maintain a specialized technical design division and dynamic production lines. We boast the internationally recognized ISO9001:2015 quality management standard alongside a complete environmental management structure to fulfill rigorous eco-compliance requirements worldwide.
"Committed to being an excellent POGO PIN manufacturer for both quality and cost at home and abroad, while leading global connector technology development."
Of specialized design and high-volume manufacturing experience with over 4,000 successful OEM/ODM clients.
Intellectual property patents covering proprietary spring systems, advanced structural designs, and customized magnet layouts.
Rigorous automated optical and electrical testing during production and prior to dispatch to secure a zero-defect exit rate.
Trusted manufacturing partner for brands such as Samsung, Honeywell, Siemens, ZTE, Luxshare, and Amphenol.
Delivering dependable connectivity requires careful material selection and design integration. Below is the technical roadmap our engineers employ to customize magnetic interfaces for commercial and industrial use.
Using N52 neodymium magnets, we adjust attraction forces (ranging from 150g to 1200g) based on the application. The system's polarity prevents incorrect insertion, and its breakaway design helps protect fragile device ports from tension damage.
Standard connectors handle low currents, but our custom pogo pin configurations manage 2A to 30A. Solid plunger designs and low-resistance plating configurations prevent thermal issues during fast charging.
By combining power contacts with impedance-matched RF and high-speed data pins, our custom interfaces support USB 2.0, USB 3.1, and CAN bus protocols alongside power delivery, all in a single footprint.
Our engineering roadmap responds directly to the trends toward thinner devices, automated factories, and electric mobility. We focus our research on key technology developments to keep our clients ahead in design cycles:
Standard components often fall short of meeting specific field conditions. We address real engineering challenges through targeted, application-specific designs.
Wearables require small, sweat-resistant charging connections. Using specialized gold plating and precise spring loads, our connectors handle skin moisture and dynamic movements, ensuring stable connections for Bluetooth headphones, smartwatches, and fitness trackers.
In automotive settings, connectors face intense vibration, temperature shifts, and moisture. Our vehicle-grade charging pin layouts maintain contact pressure during mechanical shock, supporting both signal integrity and high currents in modern car dashboards and charging hubs.
Medical settings demand cleanable, reliable connections. Our magnetic interfaces allow for fast, hassle-free mating and support hygienic seals, providing reliable performance in diagnostic monitors and portable medical instruments.
Industrial handhelds, outdoor sensors, and drone docking stations use our connectors to manage rain, dust, and wind. Sealed pogo structures and magnetic alignment enable automatic docking and reliable outdoor performance.
Our facility in Songgang, Shenzhen, benefits from the Greater Bay Area’s (GBA) manufacturing ecosystem. This local integration allows us to optimize production lead times, costs, and quality control:
To support global supply chains, our factory maintains rigorous design standardizations, chemical assessments, and quality audits.
Our quality system ensures tracebility and repeatability from initial material sourcing to final packaging. Regular audits help confirm that every production run matches the agreed engineering designs.
We use components free of hazardous materials, supporting target environmental standards. This compliance makes our parts ready for use in consumer and industrial devices worldwide.
Our engineering lab conducts life cycle tests, salt spray corrosion testing, spring force calibration, and high-current temperature monitoring to verify performance before shipping.

Find answers to technical and logistical questions about our ODM/OEM magnetic connector and pogo pin solutions.
We provide complete design flexibility, including customized pin counts (2 to 40+ pins), varied pitch spacing, distinct mechanical housing shapes, custom magnet strengths, IPX7/IPX8 waterproofing, and integrated cable assemblies. Our engineers work alongside your product team to align housing geometry and structural needs.
Standard gold over nickel can fail when exposed to human sweat and electric current. We design durable plating options using thick gold (up to 50u") or a palladium-nickel (Pd-Ni) alloy layer. This setup prevents corrosion from moisture and sweat, extending the life of wearable devices.
Our standard pogo pins are designed to handle 10,000 to 50,000 cycles. With high-durability internal springs, custom materials, and refined plating options, we can manufacture specialized contacts rated for up to 100,000 mating cycles.
Yes. Our multi-pin layouts are optimized for both power transmission (supporting fast charging up to 30A) and high-speed signal pathways. We can match impedance profiles to support protocols like USB 3.1, USB 2.0, UART, and CAN bus.
We conduct automated optical inspection (AOI) to verify structural dimensions, force displacement mapping to check spring performance, contact resistance checks, and salt spray testing. For waterproof requirements, we run automated air leak pressure testing on the line.
Our GBA location enables us to deliver 3D designs within 2 to 3 days, complete functional prototypes in 7 to 10 days, and transition to pre-production runs shortly after design approval.
