SHX33 Deep-Sea Rubber-Molded Underwater Connectors, 7000 m
7000 m rated · 3 to 16 contacts · Gigabit Ethernet version
Subsea and Underwater Connectors
Rubber-molded connectors rated to 7000 m, metal-shell and glass-sealed connectors, load-bearing and hybrid connectors, and watertight cable assemblies.
Underwater connectors must keep water out under pressure, survive salt water and still be easy to mate on deck. Our range covers rubber-molded connectors for sensors and subsea power, metal-shell connectors for deep-water equipment, glass-sealed connectors for oil and gas, load-bearing connectors for towed arrays, optical-electrical hybrid connectors and watertight cable assemblies built to your length. Contact counts, cable lengths and materials can be customized.
The SHX30, SHX33, SHX34 and SHX35 rubber-molded families are rated to 7000 m operating depth, with 70 MPa pressure ratings both mated and unmated. Specifications on each page state the test condition — depth, mated or unmated pressure — separately.
For equipment that needs a metal shell, SHX4 (10 MPa mated, contacts up to 115 A), SHX13 for sonar and SHX27 for high-voltage power are made in titanium, aluminum bronze or stainless steel. SHX10 adds glass-sealed receptacles that stay gas-tight when unmated, and SM carries a 50 kN axial load through the connector for towed arrays.

How to choose
Depth and pressure
Check the operating depth and whether the pressure rating you need is mated, unmated (open face) or both.
Mating condition
Wet-mateable connectors can be mated with water on the contact faces, on deck or at the surface. Mating at depth is reviewed project by project — tell us your conditions.
Contacts and current
Rubber-molded series cover 1 to 16 contacts, with a single-contact 250 A power version (SHX34); metal-shell series cover up to 128 contacts (SHX10) and up to 115 A per contact (SHX4, SM).
Power plus data
GDM combines power contacts with four single-mode or multimode optical fibers.
Cable and materials
Plugs are molded to the cable at your specified length; bulkhead receptacles are available in stainless steel or brass.
Options beyond the standard connector
Hybrid power and fiber
GDM with 4 optical channels.
Subsea power, 250 A

Frequently asked questions
What does 7000 m rated mean?
The SHX30, SHX33, SHX34 and SHX35 families are rated to 7000 m operating depth, with 70 MPa pressure ratings both mated and unmated. Each product page lists these values separately.
Can your connectors be mated underwater?
Our wet-mateable connectors can be mated with water on the contact faces, on deck or at the surface. If you need to mate or unmate at depth, tell us the depth and conditions and we will review it for your project.
Do you make custom cable assemblies?
Yes. We vulcanize connectors to the cable in the length you need — single-ended, double-ended or multi-branch. Send us the cable type, length and pin-out.
What is the lead time?
Samples typically take 4–8 weeks and production orders 4–8 weeks. Send us your requirements and we will confirm the lead time with the quotation.
