The connector is a 4-contact, USB 2.0 plug rated at 1.5A per contact and 30VAC, with gold-plated contacts that resist corrosion through repeated mating cycles in damp environments. ## What the IP67 Rating and 50 Mating Cycles Mean for Your Build The IP67 rating means this plug, when mated with its corresponding IP67-rated receptacle, is sealed against dust ingress and temporary immersion in 1 meter of water for 30 minutes. This is the primary reason to choose this connector over a standard unsealed USB-A plug — it survives outdoor rain, washdown cleaning, and condensation inside enclosures. The trade-off is the 50 mating cycle rating, which is lower than a typical office-grade USB port rated for thousands of cycles. The seal gasket and bayonet coupling wear with each mate, so this connector is best specified for semi-permanent installations or equipment that is connected and disconnected only during maintenance, not for daily plug/unplug use. The circular bayonet coupling secures the mated pair with a twist-lock action, providing mechanical retention that resists vibration and accidental disconnection.","metaTitle":"1954637-1 TE Connectivity USB-A Plug, IP67, 1.5A, 30VAC","metaDescription":"1954637-1 TE Connectivity USB-A (USB TYPE-A) plug, IP67 sealed, 4 contacts, 1.5A, 30VAC, USB 2.0, gold contacts, 50 mating cycles.
