Originally SEA CON®'s well established MINI-CON range was originally developed for the purpose of supplying small diameter, high density and high pressure connectors. Dry mateable, this connector series is manufactured from 316 Stainless Steel as standard, although other materials are available upon request including Titanium and Monel™. The inserts are manufactured from Glass Reinforced Epoxy (GRE) with copper alloy, gold plated contacts although glass sealed inserts are also available for high pressure applications. The MINI-CON series also offers optical and hybrid versions along with PBOF, PBOF-HP (High Pressure), reversed miniature inserts and self wiping miniatures. For more information please refer to pages 4-5 of this brochure.
With the introduction of the MIN-D and MIN-E connectors, the MINI-CON connector series is now available in 13 shell sizes with 1 to 203 contacts including coax and has a pressure rating of upto 20,000 psi (approximately 45,000 ft/13,700m).
The MINI-CON range has been supplied to numerous Naval programs and has become the connector choice for a number of navies around the world. Other applications include drilling systems, umbilical links and ROV's.
Before the MINI-CON series was first introduced, it underwent type approval testing and since then the range has been subjected to additional testing for specific projects or programs, some of which are listed below.
Salt Spray (Corrosion)
Humidity (Steady State)
Thermal Shock
Hydrostatic Pressure
Underwater Explosion Shock

Hipot upto 20,000 VAC at 5mA.
Insulation Resistance of upto 100G at 2,500 VDC.
DC resistances in µ ohm.
In addition, SEA CON® has four hydrostatic pressure vessels capable of testing underwater components to 1,000 psi, 10,000 psi, 18,000 psi and 20,000 psi. Connectors can be tested mated or in an open face condition and tests can be performed in water or oil. Electrical properties can often be monitored during the pressure cycling process.

UNDERWATER MINIATURE ELECTRICAL DRY-MATE CONNECTORS
To meet the ever increasing demand for smaller high density connectors, SEA CON® developed the Micro MINI-CON series. This miniature connector series incorporates all of the engineering concepts and design features of our highly successful MINI-CON range, but in a smaller configuration ranging in size from 1/2" to just over 2" in diameter.
In order to maintain the miniaturization and provide minimal wall thickness, special o-rings were developed to seal the interfaces on all plugs and receptacles. The inserts and bulkhead connectors are retained using Shape Memory Alloy (SMA) retaining rings manufactured from a non-corrosive material and designed to be as thin as possible but without compromising reliability. The memory characteristic is extremely beneficial when there is a need to remove the insert from the shell.
The Micro MINI-CON inserts are aligned so that the key engages first before the o-ring and electrical contacts become seated (scoop proof). The key is also designed to engage and secure the insert in the axial and rotational planes.
In many applications a flange mounted receptacle is preferred instead of a screw-in type, however SEA CON® has designed a modular flange that fits over the screw-in type eliminating the need to purchase a separate shell, again without compromising performance.
The Micro MIN-CON dry-mateable connector range is available in 6 different shell sizes ranging from 4 to 202 contacts with a pressure rating of 13,500 psi mated and is also available in a fiber optic configuration (please see our Optical Dry-Mate Hybrid section). In addition, this series also offers the option of right angles, over-molding of the cable plug, field installing the cable using boots or terminating with a Pressure Balanced Oil-Filled (PBOF) system.
The Micro MINI-CON is suitable for a variety of applications including cameras and lights or any application where size is an issue.
The Micro MINI-CON range of connectors have been subjected to the following testing:-
Humidity (Steady State)
- Tested in accordance with MIL-STD-202, Method 103.
Thermal Shock
- Tested in accordance with MIL-STD-202, Method 107.
Mechanical Shock
- Tested in accordance with MIL-S-901, Grade A, Class 1.
Hydrostatic Pressure
- Tested in accordance with MIL-STD-202, Method 1006
Vibration
- Tested in accordance with MIL-STD-202, Method 301.
Dielectric Withstand Voltage
- Tested in accordance with MIL-STD-202, Method 301.
Insulation Resistance
- Tested in accordance with MIL-STD-202, Method 302.
