It implements the USB 2.0 specification, meaning it supports data transfer up to 480 Mbps and is backward-compatible with USB 1.x peripherals. The connector has 4 contacts in a single port, arranged in the classic Type-A layout. The housing is shielded with a steel and stainless steel shell, which provides the EMI containment needed to pass FCC and CE radiated emissions limits for a USB port. The shield also doubles as the ground return path for the cable braid.
The 1A per contact limit means the VBUS pin can supply up to 1A to a downstream device — enough for charging a phone or powering a USB hub, but not for high-power USB-C PD applications. The 30VAC rating is the voltage withstand between contacts and to the shield; it is not a working voltage for the VBUS line, which is nominally 5VDC. The contact finish is listed as gold or gold-palladium, which supports this cycle life without contact fretting or resistance rise. For a field-service or frequently reconnected port, this is a solid choice.
