The MS3116R-12-4S is a vertical circular connector designed based on the MIL-DTL-26482 Series I structure. The front end of the product is equipped with four female contact points, featuring a military green metal housing, an annular knurled operating section, and a snap-lock locking mechanism. The product can be paired with a chain-style protective cap to protect the interface when the connector is temporarily disconnected.

In electrical systems, this product is used to establish plug-in multi-contact connections, enabling device wiring harnesses to reliably mate with connectors featuring matching interfaces. Compared to directly fixed wiring, circular detachable connectors facilitate equipment maintenance, wiring harness replacement, and modular assembly.

Industrial equipment and control systems must balance reliable electrical connectivity with convenient maintenance. Permanently wired connections may require additional disconnection and rewiring during equipment repair, module replacement, or harness upgrades. The MS3116R-12-4S combines four female socket contacts with a detachable bayonet interface, consolidating multiple electrical connections into one connector and simplifying harness organization, inspection, and replacement.

For projects involving periodic maintenance, modular equipment installation, or volume harness assembly, a properly specified four-pin circular connector can help standardize interface configurations, reduce repetitive wiring work, and improve maintenance procedures.

Key Performance Advantages

Consistent Harness Interface Design

The four-contact interface consolidates multiple electrical connections into a single connection point, helping engineers define wiring diagrams, identify contact positions, and standardize assembly requirements for volume production and subsequent servicing.

Supports Modular Equipment Design

The plug-in connection supports functional module separation in equipment design and simplifies harness replacement, module upgrades, and equipment reconfiguration.

Helps Reduce Interface Mismatches

The complete part number, contact arrangement, and polarization provide useful identification criteria during selection, assembly, and inspection.

Typical Applications

◆ Equipment Repair and Replacement Projects

Can serve as a replacement candidate for repair, equipment upgrades, and harness renewal after compatibility verification. Confirm the complete part number, shell size, contact arrangement, polarization, and electrical ratings before replacement.

◆ Electromechanical Equipment and Equipment Harnesses

Suitable for electromechanical assemblies and custom harness projects requiring four electrical connection positions, consolidating multiple wires into a standardized connector interface.

◆ Instrumentation and Testing Systems

Can be used in testing equipment, measuring instruments, and control units that require detachable interfaces, facilitating maintenance, module replacement, and harness inspection.

Product FAQ

How Can Misalignment or Damage During Connector Mating Be Prevented ?

Before mating, inspect the contacts, insulating insert, and bayonet area for foreign objects, deformation, or damage. Align the connector using its polarization features and follow the prescribed mating procedure. If unusual resistance occurs, stop and check the part number, keying, and alignment instead of forcing the connection.

How Can You Determine Whether This Four-Contact Connector Suits Existing Equipment ?

Selection should consider the original connector's complete part number, shell size, contact arrangement, polarization, installation clearance, and electrical requirements. Similar appearance or an identical contact count does not guarantee interchangeability. For repair or retrofit projects, review the mechanical drawings and verify compatibility through sample mating and electrical testing.

How Can the Connector Be Maintained to Reduce Contact Problems Over Time ?

Periodically inspect the contacts for contamination, corrosion, deformation, or abnormal wear, and verify that the bayonet mechanism operates correctly. Follow the manufacturer's cleaning recommendations and avoid tools or chemicals that may damage the insulation or contact plating. Discontinue use and arrange a professional inspection if loose contacts or structural damage are found.

Can Premier Cable Provide Custom Cable Assemblies and Wholesale Supply ?

Custom assembly and bulk purchasing options can be evaluated according to project requirements. When requesting a quotation, provide the cable length, conductor specifications, opposite-end connector, wiring diagram, required accessories, and testing requirements to confirm the configuration and manufacturing feasibility.
