Explore our highly customized spring-loaded connector series engineered for optimal electrical performance and mechanical durability.
Magnetic charging connectors are redefining the physical layout interfaces of electronic hardware globally. Specifically, the two pin magnetic charger—consisting of a positive pin (V+) and a ground/negative pin (GND)—has emerged as the design-standard for devices requiring rapid, water-resistant electrical coupling. Integrating neodymium permanent magnets (NdFeB) directly into the connector housing enables a self-aligning, break-away coupling that mitigates physical wear while optimizing safety parameters.
The standard composition of a precision 2-pin magnetic charging interface relies heavily on the design of the internal Pogo Pin (spring-loaded probe). Each pogo pin consists of three core components: a plunger, a spring, and a barrel. Under mechanical compression, these components maintain constant electrical contact with the target landing pad (solid contact brass receptacle), ensuring uninterrupted power flow even when subjected to dynamic vibrations or spatial offsets.
For custom hardware implementations, engineering teams must evaluate physical attributes such as current rating (typically ranging from 1A to 15A for high-current variants), spring compression force (typically 30g to 120g), contact resistance (less than 30 mΩ), and lifecycle endurance (ranging from 10,000 to over 1,000,000 compressions). Our technical department operates dynamic testing arrays to match custom application specifications exactly.

Global procurement specialists are tasked with balancing cost minimization alongside uncompromising quality metrics. Contracting with a factory based in Shenzhen, China—specifically inside the technological hardware industrial corridor of Songgang Street in the Bao’an District—unlocks unprecedented vertical supply chain integration. The region contains a hyper-concentrated network of specialized brass turn mills, high-grade plating companies (offering localized thick gold plating processes), and automated injection molding sub-contractors.
This geographic concentration allows us to run cost-effective (cheap) manufacturing pipelines without compromising mechanical tolerances. Here is how our operations in Shenzhen deliver tangible cost-to-performance advantages:
We deploy high-speed Japanese CNC lathes that turn structural brass pins down to +/- 0.01mm tolerances. This rapid machining ensures massive daily outputs, reducing per-unit cost bases dramatically.
Proper plating determines connector life. Our processing capabilities offer tailored coatings (Nickel barrier, Gold flash, Palladium-Nickel alloy) for optimized wear, corrosion, and sweat resistance.
Having in-house prototyping and injection molding tooling facilities reduces initial non-recurring engineering (NRE) fees, delivering custom shell configurations under short lead times.
Furthermore, navigating international compliance frameworks (RoHS, REACH, CE) requires structured oversight. Working directly with an ISO9001:2015 certified manufacturer ensures that all incoming base metals, plastic resins, and raw magnets pass rigid chemical trace analyses, preventing expensive cross-border shipment rejections or downstream field failures.
Established in 2011, a leading pioneer in POGO PIN development and precision connectivity technologies.
Our company was founded in February 2011 in Songgang Street, Shenzhen, specializing in the development and manufacturing of Pogopin connector; After years of efforts and sedimentation, the company gradually became a leader in the industry.
Our company is mainly engaged in research and development, production, sales of various models of POGO PIN (also known as spring thimble) products.
Our company’s spirit of "customer first, integrity first" principle, has a strong POGO PIN industry technology production team, and a number of enterprises to establish a long-term cooperative relationship. Our company has obtained ISO9001:2015 version of the international authoritative quality management system certification, has a strong quality management team and environmental management system, to provide customers with all kinds of high quality and environmental protection requirements of the products.
Equipped with high-performance turning centers that continuously turn precision connector needles and barrels.
Ensuring cleanliness during assembly, spring insertion, magnetic pressing, and initial functionality testing.
Advanced electrical force testing, optical profiling, and resistance testing loops to secure absolute zero-defect rate.
Two pin magnetic charging connectors offer critical advantages across varied industrial, commercial, and customer segments. Eliminating structural port openings protects internal circuit traces from external ingress vectors, ensuring reliable operations under challenging operating conditions.
Our engineered solutions are integrated across major device platforms: Smart wearable products (wristbands, watches), mobile phones (mobile antenna), digital cameras, laptops, Bluetooth headsets, learning machines, games products, handheld game consoles, GPS satellite navigation, aerospace electronics, medical equipment, military communications, toys, and portable electronic products.
Since the establishment of Our company, our spirit of "excellent quality, intimate service" concept, "customer-centric, create more value for customers" core values, these help us win the majority of customers.
For smart wristbands, health-tracking rings, and Bluetooth earphones, continuous human sweat contact degrades standard copper pins. Our specialty gold plating over nickel barrier layers prevents galvanic corrosion, providing years of safe, reliable operations.
Medical monitoring devices demand high signal integrity and rapid break-away connections for patient mobility safety. Our medical-grade magnetic adapters maintain low impedance over high cycling parameters.
As electronic design leans heavily towards ultra-thin profiles and smart functionalities, the demands placed on electronic interconnects are morphing rapidly. The structural limitations of traditional physical-insertion ports (USB Micro-B, USB Type-C, or standard barrel jacks) include mechanical stress fatigue, susceptibility to liquid intrusion, and dust accumulation inside the connector cavities.
To circumvent these physical flaws, manufacturing ecosystems are shifting wholesale toward magnetic coupling systems. Key macro trends shaping the market include:
Clear, technical, and actionable answers regarding design, manufacturing, custom tooling, and sourcing of 2-pin magnetic charging systems.
