Ms27484t8b35s D38999 Series Shielding Plug Circular Connector Electrical Wire Connector
MS27484T8B35S Threaded Plug, MIL-DTL-27484
The MS27484T8B35S is a threaded circular electrical connector plug designed for aerospace, avionics, and industrial platforms. It conforms to MIL-DTL-27484 (formerly MS27484) requirements. Note: MIL-DTL-27484 is a distinct standard, separate from MIL-DTL-26482 Series 1 (MS3106), MIL-DTL-26482 Series 2 (62GB), MIL-DTL-38999 / GJB599, MIL-DTL-27473 (MS27473), MIL-DTL-27497 (MS27497), MIL-DTL-27508 (MS27508), JY27466 (GJB), 8D series, Y50 series, YLH series, ZH8525 series, YH3116 series, YW1 series, and SMA RF coaxial connectors, and is not directly form-fit-function interchangeable with any of those connectors unless confirmed by the supplier.
This threaded plug features shell size 8 (approximately equivalent to D38999 shell size A / 9), shell letter B, insert arrangement 8B-35 (13 contacts: 13 x #22D signal, Service Class M - sealed), socket contacts (S), and normal keying (no suffix). The "T" style designation indicates a threaded coupling type. The design supports EMI shielding, scoop-proof mating, self-locking threaded coupling, and removable crimp contacts.

Installation Notes
- Verify shell size 8, insert arrangement 8B-35, socket contacts, and normal keying before mating.
- Use the correct crimp tooling for #22D signal contacts specified by arrangement 8B-35.
- Fully engage the threaded coupling with the mating MS27484 connector until securely seated.
- Mate only with MIL-DTL-27484 (MS27484) connectors of the same shell size 8, shell letter B, arrangement 8B-35, opposite contact gender (pin), and normal keying. Note: arrangement 8B-35 is Service Class M (sealed) — suitable for environments requiring environmental sealing.
- Do NOT attempt to mate with MIL-DTL-26482 Series 1 (MS3106), MIL-DTL-26482 Series 2 (62GB), MIL-DTL-27473, D38999/J599 Series III, MS27497, MS27508, JY27466, 8D, Y50, YLH, ZH8525, YH3116, YW1 series, or SMA RF coaxial connectors — MIL-DTL-27484 is a different standard and is not interchangeable unless confirmed by supplier.
