USB micro AB Receptacle for Damp or Field-Service Gear
The solder retention feature adds anchor pads to the footprint — they take the peel force off the signal pins when the cable gets yanked, which is the usual failure mode on a panel-mounted USB port. The splash-proof ingress protection means it can handle condensation, rain spray, or a wash-down hose — but it is not submersible.
Current Rating and Pin Assignment
The current rating is listed as 0.5A, 1A, 1.8A — these are per-contact limits that reflect the USB pinout. In a standard micro USB, the VBUS pin carries the supply current while the data pins handle only signal-level current. The 1.8A figure likely applies to the VBUS pin, and the 0.5A to the data and ID pins. For a 5-contact micro AB, the pinout is VBUS, D-, D+, ID, and GND. The ID pin is used for On-The-Go host negotiation and draws negligible current. The 30V rating is standard for USB VBUS and covers any charging voltage within that ceiling.
The steel/stainless shell provides EMI shielding for the differential data pair.
