BIRNS Millennium miniature, high-density metal shell connectors are the most advanced connectors of their type. They're tough, built for effective sealing, adaptable-- and permit the use of 22, 20, 16, 14, and 10 AWG contacts in the same connector. They reliably transmit huge data streams while minimizing electrical noise, and are easy to use. Class A pressure rating, heat-treated BeCu sockets, gold plating, and QQ-P-35 type VI passivated AISI Type 316 bodies are standard; alternate materials are available.
a, High contact density for maximized payload efficacy
b, Excellent performance with extreme data signal loads

f, Thick gold plating of contacts per MIL-G-45204, Type II, Class 1 (50 microns of hard gold)
g, Heat-treated BeCu sockets

BIRNS Penetrators reliably transmit electrical power or signal through a pressure boundary without compromising the boundary integrity, and offer:
a, Minimal maintenance
b, Excellent for long-term deployment
c, Decreases system complexity
d, Ideal for reduction of dependence on operator skill
e, Pressure resistance
f, Test options include testing per NAVMAT P-9290

BIRNS M24231 Connectors are produced in accordance with USA Military Specification MIL-C-24231D(SH), which specifies various Types of underwater electrical connectors commonly known as "Portsmouth" connectors.
BIRNS also produces similar connectors not controlled by the Specification. Examples include coaxial connectors, and certain proprietary connectors designed to obviate some of the problems commonly associated with the standard M24231 and/or EB 3004 models. BIRNS also offers M24231 connectors with Cable plugs with GRE (Glass-Reinforced Epoxy) bodies, per MIL-C-24231/30(SH).

The Subconn Micro Connector series as the name implies is designed to fit on underwater flanges, instruments or sensors where space is restricted. The contacts are the same size as the Standard Circular series, and the contact configuration is from 2 to 16 contacts. A right angle bulkhead connector is available in a contact configuration from 2 to 8 contacts. The Micro connector are rated 300 V at 10 Amp depending upon the contact configuration. The Bulkhead connector comes with Teflon leads whilst the in-line connector cable are of the water resistant SOOW type.

The Low Profile as the name implies is designed to fit on underwater flanges, instruments or sensors where height is restricted or a "neater" solution is required. The contacts are the same size as the Standard and Micro Series. The Low profile and Micro Low Profile Series are available with 2 to 9 contacts rated 300 to 600 V at 5 to 15 Amp depending upon the contact configuration. The Bulkhead connector comes with Teflon leads whilst the in-line connector cable are of the water resistant SOOW type.

The Subconn Circular Connectors are available in 4 shell sizes with up to 16 contacts rated for 300 to 600 V at 15 Amp depending upon the contact configuration. The standard products include in-line and bulkhead connectors with pressure proof dummy connectors. Standard connectors are manufactured from high grade neoprene with Naval Brass bulkhead bodies. The Bulkhead connector comes with Teflon leads whilst the in-line connector cable are of the water resistant SOOW type.

The Subconn Metal Shell Series was introduced as an alternative to the Standard Circular and the Micro Series bulkhead connectors where a more rugged and protected connector is required. The Metal Shell Series manufactured from Stainless Steel is available in 3 shell sizes compatible with industry. Flange and bulkhead male and female versions are standard. The contacts are the same size as the Standard Circular series, and the contact configuration is from 2 to 16 contacts. A right angle bulkhead connector is available in a contact configuration from 2 to 8 contacts. The Micro connector are rated 300 V at 10 Amp depending upon the contact configuration. The Bulkhead connector comes with Teflon leads whilst the in-line connector cable are of the water resistant SOOW type.

The Power series of Subconn connectors was introduced to meet the growing demand for increased power requirements in underwater systems. There are currently 4 standard connectors in the series with a number of "special" connectors which are listed in the Specials section.
The series comprises a single contact welding connector, two battery charging connectors and a high power contact connector.

A large number of special connectors designed for specific applications have been produced by subconn over the last 20 years. All connectors use the proven unique Subconn contact design, and are for the most part rated for deep water applications.

The increasing demand for deep water technical solutions to data transfer and communications has seen the development of the OptoLink underwater connector, which is based upon proven expanded beam technology and the industry standard Subconn wet mateable electrical connector.
The trend towards single mode technology demanded a reliable underwater expanded beam connector but problems were encountered reflection from lenses used in the multi-mode designs. New designs were developed and the breakthough came in 1999 with the advent of the new expanded beam "ball lens" which produced the results required.
