Ms27484t12f04shn43 Multi Pin Shielded Plug Electrical Wire Connector Ms27484

MS27484T12F04SN Threaded Circular Plug, MIL-DTL-27484

The MS27484T12F04SN is a threaded circular electrical connector plug designed for aerospace, avionics, and industrial platforms. It conforms to MIL-DTL-27484 (formerly MS27484) requirements. Note: MS27484 is a distinct standard from MIL-DTL-38999 / GJB599, from MIL-DTL-27497 (MS27497), and from MIL-DTL-27508 (MS27508), and is not directly form-fit-function interchangeable with D38999/J599 Series III, MS27497, or MS27508 connectors.

This threaded plug features shell size 12 (approximately equivalent to D38999 shell size C / 13), insert arrangement 12F-04 (3 contacts: 3 x #16S power, Service Class I - non-sealed), socket contacts (S), and normal keying (N). The "T" style designation indicates a threaded plug. The design supports EMI shielding and removable crimp contacts.

Product Features

• Conformant to MIL-DTL-27484 (MS27484) circular connector standard
• NOT directly interchangeable with MIL-DTL-38999 / GJB599 Series III, MIL-DTL-27497 (MS27497), or MIL-DTL-27508 (MS27508) connectors
• Threaded coupling for secure mating retention
• Threaded plug style (T designation) for cable-end or panel-mount applications
• Conductive shell for EMI shielding and corrosion resistance
• Non-sealed power configuration with insert arrangement 12F-04: 3 x #16S power contacts (Service Class I - non-sealed)
• Socket contacts (S) for mating with pin-contact receptacles
• Normal keying (N) for standard polarization and anti-mismatch mating

Compatible Applications

The MS27484T12F04SN threaded plug is intended for platforms that require MIL-DTL-27484 compliant threaded interconnects with low-count non-sealed power circuits in shell size 12, using socket contacts. Typical use cases include:

• Aircraft and helicopter wiring harness cable ends (MIL-DTL-27484 standard)
• Avionics LRUs, radar, and communication equipment
• Ground vehicles and rugged electronic enclosures
• Shipboard and industrial equipment requiring power circular connectors
• Programs that standardize on MIL-DTL-27484 (MS27484) interfaces

Selection Guide

Installation Notes

• Verify shell size, insert arrangement, contact gender, and normal keying before mating.
• Use the correct crimp tooling for #16S power contacts specified by arrangement 12F-04.
• Fully engage the threaded coupling with the mating MS27484 receptacle until securely seated.
• Mate only with MS27484 receptacles of the same shell size, arrangement, opposite contact gender (pin), and normal keying. Note: 12F-04 is Service Class I (non-sealed) — not suitable for applications requiring environmental sealing.
• Do NOT attempt to mate with D38999/J599 Series III, MS27497, or MS27508 receptacles — MS27484 is a different standard and is not interchangeable.

Why Choose MS27484T12F04SN

MIL-DTL-27484 Compliance

Choosing MS27484T12F04SN ensures compliance with MIL-DTL-27484 (formerly MS27484) requirements for programs that mandate this specific standard. The threaded plug geometry supports reliable cable-end interconnect with non-sealed power capability, socket contacts, and normal keying for aerospace and industrial systems. Note: this connector is NOT a direct replacement for D38999/J599 Series III, MS27497, or MS27508 parts.

Ordering Information

Order by the MS27484 designation MS27484T12F04SN. When requesting a quote, please confirm mating receptacle part number (pin contacts), shell finish class, contact plating, and required quantity. Note: 12F-04 is Service Class I (non-sealed); specify 12F-35 for sealed signal applications.
