Contact system and sealing
The MUSBR-E551-30 is the 5-contact USB mini AB receptacle in Amphenol ICC's MUSBR series, specified for USB 2.0 and shielded for signal integrity. Gold-plated contacts rated 1 A, 5000 mating cycles, and an IP67-rated shell with a steel, stainless shield — the sealing and plating support repeated field mate/unmate in wet or dusty environments.
Durability and environmental fit
The 5000-cycle durability and gold finish mean the receptacle tolerates frequent reconnection without contact fretting — the IP67 rating and UL94 V-0 housing extend its use to industrial enclosures and outdoor equipment where moisture and flame rating are specified.
