The MS3116J14-12S is a 12-position military circular electrical connector offered by Premier Cable. It belongs to the interface family associated with MIL-DTL-26482 Series I and is designed for specialized equipment and cable assemblies requiring multiple electrical connections.According to the supplied product drawing, the connector features a circular multi-position interface with 12 electrical positions and a combination of two different contact sizes.

The corresponding 14-12 insert arrangement consists of:

8 contact positions in size 20.
4 contact positions in size 16.

This mixed-size arrangement allows different wire circuits to be organized within a single connector, providing greater flexibility in equipment wiring design.Compared with connectors using only one contact size, the MS3116J14-12S allows engineers to assign different wire specifications according to individual circuit requirements. It is suitable for equipment systems incorporating control, auxiliary power, and other electrical circuits.

Typical application areas include military electronics, professional communication equipment, industrial control systems, avionics auxiliary equipment, and specialized instruments.

Premier Cable developed the MS3116J14-12S to provide a multi-position connection solution with mixed-size contact arrangements.

1. Supporting Multiple Electrical Circuits

The 12-position configuration accommodates a greater number of independent electrical connections for sophisticated electronic equipment.

2. Accommodating Different Wire Specifications

The combination of size 20 and size 16 contact positions provides configuration options for different wire cross-sections and circuit requirements.

3. Improving Complex Harness Organization

Consolidating different electrical connections within one interface helps reduce distributed connection points and establish a more organized wiring structure.

Typical Applications

Military Electronic Control Systems

Suitable for military electronic control equipment, command and control terminals, and specialized electronic modules. It can provide multiple electrical connections between control units and support organized internal equipment wiring.

Avionics Auxiliary Equipment

Can be considered for compatible avionics auxiliary equipment, ground test devices, and aviation maintenance equipment requiring connections for multiple independent electrical circuits.

Professional Communication Systems

Suitable for communication control terminals, signal processing equipment, and professional communication modules, supporting connections for power, status feedback, and auxiliary control circuits.

What Is a Connector Insert Arrangement and Why Does 14-12 Matter ?

An insert arrangement is an important part of connector identification and selection. It describes the number and arrangement of electrical contact positions within a connector.

In the MS3116J14-12S designation, 14-12 identifies the corresponding shell size and insert arrangement, with 12 indicating a 12-position configuration.

Different insert arrangements within the same connector family may vary in contact quantity, contact sizes, and internal layouts.

Therefore, when purchasing or replacing a connector, buyers should verify the complete insert arrangement rather than relying solely on the MS3116 series designation.

Product FAQ

Why Can't Different Contact Sizes Be Interchanged Freely ?

Contact sizes are associated with wire specifications, compatible termination components, and electrical requirements.

Different contact sizes have different wire compatibility ranges and mechanical requirements. Uncontrolled substitutions during maintenance or cable assembly development may result in mismatched components and compromised connection quality.

Why Does the MS3116J14-12S Use Two Different Contact Sizes ?

The mixed-size design accommodates different wire specifications and electrical circuit requirements. This model combines eight size 20 and four size 16 contact positions, allowing engineers to configure circuits according to their individual requirements.

Can the 12 Positions of the MS3116J14-12S Be Assigned to Different Circuit Functions ?

Yes. Different positions can be assigned to power, control, status feedback, and auxiliary circuits according to the equipment design. The exact function of each position must be defined in an approved wiring diagram.

Can Different Cable Lengths Be Customized for the MS3116J14-12S ?

Yes. Premier Cable can customize cable lengths according to equipment installation distances, routing paths, and customer technical drawings for both prototype development and volume production.
