Sealed USB 2.0 mini-B, 5 contacts
The MUSBB55104 is a 5-contact USB 2.0 mini-B receptacle from the Amphenol ICC MUSB series, rated IP67 — but that rating holds only when the connector is mated with the corresponding plug. It carries gold-plated contacts rated for 1 A and 5000 mating cycles, with a shielded copper-alloy shell and a UL94 V-0 black insulation body.
IP67 only when mated
The IP67 rating is valid only when the receptacle is mated — the flange gasket seals against the panel face, but an unmated half exposes the contacts to washdown and dust.
