Ms27484t8b35PA Shielding Plug D38999 Ms27484 Series Circular Connector
MS27484T8B35PA Threaded Circular Plug, MIL-DTL-27484
The MS27484T8B35PA 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 8 (approximately equivalent to D38999 shell size A / 9), insert arrangement 8B-35 (13 contacts: 13 x #22D signal contacts), pin contacts (P), and keying position A (non-standard keying — requires supplier confirmation). The "T" style designation indicates a threaded plug. The design supports EMI shielding and removable crimp contacts.

Compatible Applications
The MS27484T8B35PA threaded plug is intended for platforms that require MIL-DTL-27484 compliant threaded interconnects with medium-count signal circuits in shell size 8, using pin contacts and keying position A. 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 outdoor equipment requiring circular connectors
- Programs that standardize on MIL-DTL-27484 (MS27484) interfaces
Selection Guide
| Requirement | Recommended Choice |
|---|---|
| Threaded plug, size 8 / arrangement 35 / pins / keying A (MS27484) | MS27484T8B35PA - this product |
| Mating receptacle with socket contacts and keying A | MS27484 receptacle, size 8 / 8B-35 / socket / keying A (confirm part number with supplier) |
| Socket contact version of this plug | MS27484T8B35SA |
| Normal keying version | MS27484T8B35PN |
| Larger shell size (10) with same arrangement | MS27484T10B35PA |
Installation Notes
- Verify shell size, insert arrangement, contact gender, and keying position A before mating. Keying A is non-standard — confirm with supplier that this configuration is available.
- Use the correct crimp tooling for #22D signal contacts specified by arrangement 8B-35.
- 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 (socket), and matching keying A.
- 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 MS27484T8B35PA
