Sealed USB-A Plug for Harsh Environments
It carries an IP67 rating for dust-tight and waterproof sealing, making it suitable for outdoor kiosks, marine electronics, industrial control panels, and field-deployed equipment that faces washdown or immersion. 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.
