Product Introduction

Dongguan Xinteng Electronics Co., Ltd. is one of the most reliable manufacturers and suppliers of magnetic 4 pin connector in China, featured by quality products and good service. Welcome to wholesale bulk durable magnetic 4 pin connector in stock here from our factory. Also, customized service and OEM&ODM service are available.

The Magnetic 4 Pin Connector supports DC 60V 1A current transmission, and the gold-plated pogo pins ensure excellent durability and stable conductivity. The gold layer effectively prevents oxidation during prolonged plugging and unplugging, or in humid environments. Furthermore, the male and female magnetic connectors offer a retention force of 600g, which is considered above average for similar magnetic connectors.

China supplies racetrack-shaped magnetic connectors. The racetrack-shaped design provides a more reliable and stable connection between devices and magnetic charging cables. A magnetic connector is a special type of connector whose basic structure consists of pogo pins, insulating plastic, and a magnet. The pogo pins provide contact force, and the magnets provide a stable magnetic connection, thus achieving an electrical connection between the magnetic cable and the female connector head.

Q: Will a humid or corrosive environment cause a short circuit?

A: If the magnetic pin connector is not customized for the environment, a short circuit will occur. We design connectors according to the operating environment of the equipment. For example, in humid or corrosive environments, we add sealing structures (such as sealing rings) to prevent moisture and corrosive substances from entering. We also select corrosion-resistant plating and materials, and remind users to check the protective performance regularly.

Q: Will the gold plating on a 4-pin magnetic connector fall off if exposed to the elements for extended periods?
A: Theoretically, it shouldn't fall off easily. However, it may wear out over time if frequently plugged and unplugged or exposed to dust or salt spray. It's recommended to regularly wipe gently with an alcohol wipe; avoid scraping with hard objects. High-quality gold plating (≥1μm) significantly extends the lifespan.

Q: Will high temperatures cause performance degradation?
A: No, firstly, we use high-temperature resistant base materials (such as ceramics and high-temperature resistant plastics); secondly, we need to avoid using it in high-temperature environments that exceed specifications, and add heat dissipation design if necessary.

Q: Why is it necessary to control the temperature when soldering pogo pins?
A: Because there is a spring inside the pin body. Excessive temperatures will cause the spring to anneal or lose its elasticity. Designs like these with a 260°C temperature resistance are meant for short bursts of high temperature, not prolonged exposure to high-temperature wire. Try to complete hand soldering or reflow within 3 seconds.
