Premium Ms27497t20f35PA Crimp Pin Connector for Secure Connections
MS27497T20F35PA Threaded Circular Plug, MIL-DTL-27497
The MS27497T20F35PA is a threaded circular electrical connector plug designed for aerospace, avionics, and industrial platforms. It conforms to MIL-DTL-27497 (formerly MS27497) requirements. Note: MS27497 is a distinct standard from MIL-DTL-38999 / GJB599, from MIL-DTL-27508 (MS27508), and from MIL-DTL-27484 (MS27484), and is not directly form-fit-function interchangeable with D38999/J599 Series III, MS27508, or MS27484 connectors.
This threaded plug features shell size 20 (approximately equivalent to D38999 shell size G / 21), insert arrangement 20F-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.

Selection Guide
| Requirement | Recommended Choice |
|---|---|
| Threaded plug, size 20 / arrangement 35 / pins / keying A (MS27497) | MS27497T20F35PA - this product |
| Mating receptacle with socket contacts and keying A | MS27497 receptacle, size 20 / 20F-35 / socket / keying A (confirm part number with supplier) |
| Socket contact version of this plug | MS27497T20F35SA |
| Normal keying version | MS27497T20F35PN |
| Smaller shell size (18) with same arrangement | MS27497T18F35PA |
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 20F-35.
- Fully engage the threaded coupling with the mating MS27497 receptacle until securely seated.
- Mate only with MS27497 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, MS27508, or MS27484 receptacles — MS27497 is a different standard and is not interchangeable.
Why Choose MS27497T20F35PA
