In specialized electronic equipment, industrial control systems, and mobile machinery, not every electrical connection requires a large number of contacts. Some applications need only a limited number of circuits for control signals, status feedback, auxiliary power, or other electrical functions. Selecting a connector with more contact positions than necessary can increase interface complexity and consume additional installation space.

The MS3116J12-3P addresses this type of three-circuit interconnection requirement. By integrating three male pin contacts into one circular connector, it provides a defined interface for organizing individual electrical circuits according to the system design.

Premier Cable developed this product to expand its MIL-DTL-26482 Series I three-contact connector offering and provide customers with another option featuring male pin contacts, solder termination, and a cable sealing and clamping configuration.

When paired with a compatible socket connector, appropriately specified conductors, and an approved pin assignment, the MS3116J12-3P can support custom wiring harnesses, equipment module connections, and dedicated electrical interface development. Its detachable circular interface also facilitates inspection, servicing, and component replacement in systems requiring periodic disconnection.

Technical Knowledge

What Are Analog and Digital Signals? How Do They Affect Connector Selection ?

Analog signals represent measurement data through continuously varying voltage or current, such as outputs from certain temperature, pressure, and displacement sensors.

Digital signals use discrete electrical levels to represent logical states or data and are commonly found in control commands, switching status, and digital communication systems.

These signal types have different transmission requirements. Analog signals generally require attention to noise, grounding, and signal integrity, while digital signals require consideration of logic levels, signal edges, and transmission speed.

Connector selection should therefore consider not only the number of positions but also the signal type and suitability of the cable and interface.

Product FAQ

Is the MS3116J12-3P Suitable for Low-Voltage Control Signal Transmission ?

Its suitability can be evaluated according to the actual electrical specifications. For low-voltage control signals, signal levels, connector contact resistance, cable length, and external electromagnetic interference should be considered to ensure proper signal transmission.

Can the MS3116J12-3P Be Used for Equipment Status Feedback Circuits ?

Yes. Its connection positions can be assigned to status feedback signals according to the equipment circuit design. In suitable control systems, it can connect equipment status outputs to an upper-level control module.

Can the MS3116J12-3P Be Used with Shielded Cables ?

A shielded cable configuration can be evaluated according to the connector construction and cable assembly design. For signal circuits susceptible to electromagnetic interference, suitable shielded cables may be considered, with the shielding termination and overall EMC requirements clearly defined.

What Precautions Should Be Taken When Mating and Unmating the MS3116J12-3P ?

Before mating or unmating, verify the connector model and mating interface, and inspect for foreign objects or visible damage. Follow the applicable assembly instructions and avoid pulling the cable or applying excessive force. If abnormal mating resistance occurs, stop the operation and check interface polarization and model compatibility.
