DNC-2199 is a submersible USB-C bulkhead connector with M16x1 long thread, designed for underwater camera housings that require a reliable pass-through connection for USB communication and power delivery. It is suitable for Ikelite Canon EOS R6 / R6 Mark II housings, as well as selected Aquatica and Aquatech housings with an M16x1 threaded port.
The connector features a low-profile right-angle internal USB-C plug and a 12.7 mm long thread, making it ideal for housings where extra thread length is required. It also includes Water Block protection to help preserve housing vacuum integrity and reduce the risk of water ingress.
