Waterproof USB Micro B for Harsh Environments
The JST UB-MC5BR3-SDWP604-4S-TF is a USB micro B receptacle from the UB series, designed for applications where standard USB connectors fail due to moisture or dust ingress. It carries 5 contacts in a single port, with a waterproof seal that lets it survive washdown cycles and outdoor exposure. Gold plating on the contacts and a stainless steel shell resist corrosion in humid or chemically aggressive environments.
The current rating of 1.8A on one contact is enough for charging a handheld device or powering a sensor node; the 0.5A and 1A figures apply when multiple contacts carry current simultaneously, limited by the temperature rise across the small pitch. The right-angle orientation with horizontal mounting feature places the mating face flush with the board edge — check your enclosure cutout height against the connector's overall profile before layout.
