The Flat 3-Pin Underwater Cable Connector, Male and Female Pair with Potted Pigtail is a flat-body 3-pin underwater connector pair: one male and one female half, each moulded into a slim flat shell with a stainless threaded neck and a potted white pigtail leaving the back. The flat footprint fits shallow pockets and low-profile housings where a round connector will not sit, and the potted rear keeps the cable entry watertight.

Structure & Sealing
Contacts are inserted in a moulded insulator and overmoulded into the flat thermoplastic shell; the pigtail enters through a potted gland so the seal sits between conductor and jacket, not around the outside. The stainless neck carries the sealing face for panel mounting, and both halves are keyed so the pair mates in one orientation only.
