Product Description

The USB 3.0 connector is a next-generation high-speed connector designed for compact devices that demand stable communication, fast transfer rates, and durable structural performance. Unlike traditional USB connector designs, this upgraded short USB connector version incorporates a reverse-side recessed PCB structure (1.8 mm depth) that significantly reduces vertical height, making it ideal for ultra-thin and space-limited applications.

Featuring a horizontal 90° DIP layout, a robust metal shell for EMI shielding, and a black polymer base aligned with KKG’s signature industrial style, this usb 3.0 connector delivers enhanced performance and structural integrity for modern electronics.

For devices using micro usb connector or micro usb port, this USB 3.0 Type-A upgrade offers greater speed, lower power consumption, and a much longer service life.
