MS 3102R Connector — Everything Your Engineering Team Needs to Know

When sourcing circular connectors for industrial, defence, or railway applications, the MS 3102R connector remains one of the most specified receptacle components across engineering teams in India and globally.

Whether you are a design engineer integrating a control panel or a purchase manager raising a procurement order, understanding the MS 3102R datasheet, dimensions, and application fit is critical before you buy.

What Is the MS3102R Connector?

The MS 3102R is a box mounting receptacle circular connector that conforms to the MIL-DTL-5015military specification. It is part of the MS (Military Standard) connector family, widely used where reliable, ruggedised electrical connections are required in demanding environments.

The MS 3102R is designed for permanent installation into equipment enclosures or shielded boxes, providing a fixed mating interface for cable plugs. It features a threaded coupling mechanism, making it highly resistant to vibration, shock, and harsh operating conditions while providing enhanced environmental protection.

MS 3102R Key Specifications

  • MIL-DTL-5015 compliant circular receptacle
  • Box mounting design for fixed installations
  • Threaded coupling mechanism
  • Multiple shell sizes and insert arrangements
  • Available with various contact configurations
  • Suitable for industrial, defence, railway, and power applications
  • Durable construction for high-vibration environments

MS 3102R Dimensions — What to Check Before Specifying

MS 3102R connectors are available across multiple shell sizes, with varying numbers of contacts and insert arrangements. The most commonly specified shell sizes in Indian industrial and defence procurement are Size 10SL, 12, 14, 18, 20, 22, 28, and 40, each offering different pin counts and current-carrying capacities.

When reviewing the MS 3102R datasheet, pay close attention to:

  • Insert arrangement code — determines pin count and layout
  • Contact size — affects current rating and carrying capacity
  • Shell size — determines the physical diameter and mating envelope
  • Finish type — cadmium for standard environments, nickel for corrosion-sensitive applications

Errors in specifying any of these will result in a connector that physically fits but electrically underperforms, which can be a costly error to correct post-installation.

Mating Connectors — What the MS 3102R Works With

The MS 3102R is a receptacle only — it must be paired with the correct mating plug to complete the assembly.

Within the MIL-DTL-5015 family:

  • MS 3106F — straight cable plug, the most common mating counterpart
  • MS 3108E — 90-degree elbow plug, used where cable routing space is restricted

Always specify shell size, insert arrangement, and contact type consistently across the mating pair. Mismatched insert arrangements will prevent correct mating even if the shell sizes are identical.

Where Is the MS 3102R Connector Used?

The MS 3102R connector is specified across multiple sectors:

Indian Railways

Equipment enclosures, control panels, signalling systems, and traction electronics.

Defence & Aerospace

Vehicle-mounted systems, avionics ground support equipment, and communication racks.

Power Plants

Instrumentation panels, high-vibration equipment enclosures, and DCS cabinets.

Industrial Automation

Motor drives, control cabinets, and machine wiring termination points.

Its MIL-spec pedigree makes the MS 3102R connector the preferred choice wherever field failure is not an option and the connector must remain reliable over extended service intervals.

Sourcing MS 3102R Connectors in India

When evaluating an MS 3102R connector supplier in India, prioritise manufacturers who carry ERTL/LCSO certification, maintain an in-house quality testing laboratory, and offer competitive lead times—especially for urgent or project-critical procurement requirements.
