Ms27484t12f04shn43 Multi Pin Shielded Plug Electrical Wire Connector Ms27484 Series
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.

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
| Requirement | Recommended Choice |
|---|---|
| Threaded plug, size 12 / arrangement 04 / sockets / normal keying / non-sealed (MS27484) | MS27484T12F04SN - this product |
| Mating receptacle with pin contacts | MS27484R12F04PN |
| Pin contact version of this plug | MS27484T12F04PN |
| Smaller shell size (10) with power arrangement | MS27484T10F04SN |
| Sealed signal arrangement (Service Class M) | MS27484T12F35SN |
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.
