When sourcing circular connectors for industrial, defence, or railway applications, the MS 3108F connector is a go-to choice across engineering teams in India and globally, especially wherever cable routing needs to turn a tight corner.
Whether you are a design engineer building a control panel or a purchase manager raising a procurement order, understanding the MS3108F datasheet, dimensions, and application fit is critical before you buy.
What Is the MS 3108F Connector?
The MS 3108F is a right-angle (90°) plug circular connector that conforms to theMIL-DTL-5015 military 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 3108F is functionally similar to the MS3106 straight plug but is built with a 90° angled backshell, making it the preferred choice where cable clearance is limited or wiring needs to exit at an angle rather than straight out of the mating face. Like its straight-plug counterparts, it uses a threaded coupling mechanism, making it highly resistant to vibration, shock, and accidental disconnection — a non-negotiable requirement in defence, aerospace, and heavy industrial settings.

MS3108F Dimensions — What to Check Before Specifying
MS 3108F 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 3108F datasheet, pay close attention to:
- Insert arrangement code — determines pin count and layout
- Contact size — affects current rating
- Shell size — determines the physical diameter and mating envelope
- Backshell orientation — the 90° exit direction must clear surrounding hardware, cable trays, or enclosure walls
- 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 or worse, a backshell angle that fouls the enclosure. This is a costly error to correct post-installation.
Where Is the MS 3108F Connector Used?
The MS 3108F is specified wherever space is tight, and a straight plug simply won’t clear the panel:
- Indian Railways — control panels, signalling systems, and traction equipment with confined wiring bays
- Defence & Aerospace — ground support equipment, communication systems, avionics interconnects in tight bulkhead spaces
- Power Plants — instrumentation panels and high-vibration equipment enclosures with limited clearance
- Industrial Automation — control cabinets, motor drives, and machine wiring where cables must exit sideways
Sourcing MS 3108F Connectors in India
When evaluating an MS 3108F connector supplier in India, prioritise manufacturers who carry ERTL/LCSO certification, maintain an in-house quality testing lab, and offer the shortest lead times in the industry, especially for urgent or project-critical procurement.
