The Ultra Miniature Multi Pin Male Bulkhead Connector for Deep Sea Rov is an IP68-rated ultra-miniature circular connector built for the smallest subsea packages: miniature sensor pods, inspection-class ROV add-ons and compact instruments. Multi-pin gold-plated contacts pass power and signal through one sealed penetration, and the threaded coupling nut keeps the mating face watertight in service. The bulkhead pattern mounts through a housing wall: the wet side mates outside, the dry side is wired inside.

Structure & Sealing
Contacts are carried in a molded insulator inside machined metal housing with marine-grade plating. Sealing is achieved by an O-ring face seal on the mating interface and a potted cable exit on the rear; the threaded coupling nut holds the pair together under tension without tools. When mated, the seal faces compress so the wet-side circuit stays isolated from the dry-side housing.
Applications
- Inspection-class ROV / AUV harnesses and small tooling interfaces
- Miniature subsea sensors, imaging heads and sonar pods
- Compact oceanographic and environmental monitoring instruments
- Underwater lights, small actuators and slim pressure housings
Customization & OEM
- Pin count, contact type and shell size built to order.
- Cable length, jacket material and pigtail terminations to your drawing.
- Shell material options: brass, stainless steel 316L; PEEK or rubber over-molding.
