Specs that seal the deal
The MUSB-K552-30 is a USB 2.0 micro AB receptacle from Amphenol ICC's MUSB series, carrying 5 gold-plated contacts in a shielded steel shell. Rated IP67 dust-tight and waterproof, it mounts via a horizontal flange with through-hole solder termination — the panel seal holds the rating, not the housing thread.
Mating cycle budget and contact finish
Gold mating contacts support 10000 mating cycles — the plating grade, not the contact beam, sets the cycle life in a sealed environment.
