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.

Important: MS27497 (MIL-DTL-27497), MS27508 (MIL-DTL-27508), MS27484 (MIL-DTL-27484), and D38999/J599 (MIL-DTL-38999/GJB599) are separate standards and are NOT form-fit-function interchangeable. Non-standard keying A requires supplier confirmation of availability.

Compatible Applications

The MS27497T20F35PA threaded plug is intended for platforms that require MIL-DTL-27497 compliant threaded interconnects with medium-count signal circuits in shell size 20, using pin contacts and keying position A. Typical use cases include:

• Aircraft and helicopter wiring harness cable ends (MIL-DTL-27497 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-27497 (MS27497) interfaces

Selection Guide

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

MIL-DTL-27497 Compliance

Choosing MS27497T20F35PA ensures compliance with MIL-DTL-27497 (formerly MS27497) requirements for programs that mandate this specific standard. The threaded plug geometry supports reliable cable-end interconnect with pin contacts and keying position A for aerospace and industrial systems. Note: this connector is NOT a direct replacement for D38999/J599 Series III, MS27508, or MS27484 parts. Non-standard keying A requires supplier confirmation.

Ordering Information
