High-Current Connection Solutions
We understand the pain points of magnetic interfaces—"misalignment on connection" and "short lifespan"—so we don't pile up specifications; instead, we focus on refining the real user experience. Through multi-pole magnetic circuit optimization and flexible contact point design, one-handed blind mating becomes smooth and natural, with no disconnection even under shaking. The fully sealed flat surface structure easily withstands sweat and moisture, remaining as tight as new after tens of thousands of insertions and withdrawals. Every solution is repeatedly validated by real users, ensuring comfort and peace of mind. No gimmicks—just the right amount of reliability and naturalness.

Pogo Pin Customization
We understand the pain points of universal pins such as "mismatched dimensions and unstable performance," so we refuse standard products and only customize the right solution for you. From pin body size to spring force and current-carrying capacity, everything is precisely matched to your needs, perfectly embedded into the device structure with stable and reliable contact. Rapid sampling in 3-5 days, flexible mass production, and one-on-one communication throughout the process to turn requirements into parameters, so customization never slows down your project progress. Every pin is verified through actual installation, ensuring it works right out of the box with lasting peace of mind. No gimmicks or rigid metrics—just thoughtful solutions that truly understand your device.

Magnetic Connection Technology
We avoid piling up specifications and instead focus on refining the natural magnetic connection experience of "smooth, durable, and reassuring." Through multi-pole magnetic circuit and spring contact design, we achieve one-handed blind mating with automatic alignment, stable connection without disconnection during movement, and long-lasting tightness. The fully sealed flat structure easily handles sweat and water stains, with IP67 waterproofing suitable for various complex environments. Every solution undergoes real-user validation to ensure accurate attraction, easy separation, and long service life. No gimmicks—just the right amount of reliability and comfort.
