Adopting an elliptical structure design, it is suitable for small space layouts, and the 5PIN configuration supports USB 2.0 data transmission (480Mbps) and 5V/3A power supply. Built in N52 neodymium iron boron magnet (adsorption force ≥ 3N), blind insertion is achieved through polarity anti reverse design, with a mechanical lifespan of 100000 insertions and removals. The terminal is made of C194 high conductivity copper plated with gold (3 μ m), and the shell is a combination of LCP and stainless steel, with a temperature resistance of -40 ℃~105 ℃. It is suitable for smart wearables, medical equipment, industrial sensors and other scenarios.
