The MS3116J8-4P is a four-position military circular electrical connector offered by Premier Cable. It belongs to the interface family associated with MIL-DTL-26482 Series I and is intended for specialized equipment and cable assemblies requiring multiple electrical connections.

This model features an 8-4 insert arrangement with four individual electrical connection positions. Each position can be assigned a different electrical function according to the equipment circuit design.Compared with a three-position connector, the four-position configuration provides an additional circuit allocation option, allowing engineers to consolidate different electrical functions within one connection interface.

The MS3116J8-4P can be used not only as an individual electrical interface but also as a connection point between equipment modules and external cable assemblies. It is suitable for military electronics, industrial control equipment, communication terminals, and professional inspection instruments.

What Can MS3116J8-4P Do ?

1. Providing More Complete Circuit Allocation

Four connection positions support combined power, control, and auxiliary signal requirements in suitable equipment.

2. Supporting Multifunctional Equipment Modules

The connector facilitates connections between electronic modules with different electrical functions, helping equipment manufacturers plan their interfaces.

3. Improving Circuit Identification

Clearly defined connection positions and wiring assignments help engineers establish consistent wire numbering and functional identification.

4. Supporting Existing Equipment Requirements

It provides an option for purchasing, maintenance replacement, and custom cable assembly development for equipment using the corresponding MS3116 interface family.

Technical Knowledge

How Should the Four Connection Positions Be Assigned ?

The four connection positions can be assigned according to actual equipment functions. For example, in certain low-voltage DC applications, they may be allocated to positive power, negative return, a control signal, and auxiliary feedback.

Other equipment may use the four positions for separate control or auxiliary circuits according to its electrical design.

During circuit allocation, operating voltage, current, wire specifications, and electrical isolation requirements should be considered to ensure that each position matches its intended circuit.

Product FAQ

Can the MS3116J8-4P Be Used in Custom Four-Wire Cable Assemblies ?

Yes. With four independent connection positions, the connector is suitable for custom four-wire cable assemblies. Premier Cable can develop compatible solutions according to customer wiring diagrams, wire specifications, cable lengths, and opposite-end connector requirements.

Can the Four Positions of the MS3116J8-4P Be Assigned to Different Functions ?

Yes. The four positions can be assigned to different electrical functions according to the equipment circuit diagram, such as power, control, feedback, and auxiliary circuits. Exact position assignments should be established during project design.

Can the MS3116J8-4P Replace a Connector in Existing Equipment ?

It can be evaluated for replacement projects where the existing equipment specifies the same interface configuration. The original complete part number, insert arrangement, mating interface, and electrical ratings should be checked rather than relying on visual similarity.

How Should the Cable Length for an MS3116J8-4P Assembly Be Determined ?

Cable length should be determined according to the actual distance between the two equipment interfaces, internal routing paths, installation allowance, and bending requirements. For complex equipment, providing a routing drawing or physical dimensions helps improve cable assembly accuracy.
