Ms27497t8b35s Amphenol Standard Circular Mil Connector Ms27497 Series Electrical

MS27497T8B35S Straight Plug, MIL-DTL-27497

The MS27497T8B35S is a triple-start threaded circular electrical connector straight 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 and is not directly form-fit-function interchangeable with D38999/J599 Series III connectors.

This straight plug features a finish class corresponding to the "T" prefix (shell material/finish per MS27497), shell size 8 (approximately equivalent to D38999 shell size B / 11), insert arrangement 8B-35 (13 contacts: 13 x #22D signal, Service Class M - sealed), socket contacts (S), and normal keying (no suffix). The design supports EMI shielding, scoop-proof mating, self-locking threaded coupling, and removable crimp contacts.

Product Features

• Conformant to MIL-DTL-27497 (MS27497) circular connector standard
• NOT directly interchangeable with MIL-DTL-38999 / GJB599 Series III connectors
• Triple-start threaded self-locking coupling for high-vibration retention
• Straight plug style for cable-end mating with receptacles
• Conductive shell finish for EMI shielding and corrosion resistance
• Sealed signal configuration with insert arrangement 8B-35: 13 x #22D signal contacts (Service Class M - sealed)
• Socket contacts (S) for mating with pin-contact receptacles
• Normal keying (no suffix) for standard polarization and anti-mismatch mating

Part Number Breakdown

Related options: MS27497R8B35PN receptacle (pin contacts, normal keying); MS27497T8B35SN plug with socket contacts (same product); MS27497T10B35S for shell size 10 (approx. D38999 size C / 13); MS27497T8B98S non-sealed arrangement. Important: MS27497 (MIL-DTL-27497) and D38999/J599 (MIL-DTL-38999/GJB599) are separate standards and are NOT form-fit-function interchangeable.

Compatible Applications

The MS27497T8B35S straight plug is intended for platforms that require MIL-DTL-27497 compliant threaded interconnects with medium-count sealed signal circuits in shell size 8, using socket contacts. 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 sealed circular connectors
• Programs that standardize on MIL-DTL-27497 (MS27497) interfaces

Selection Guide

Installation Notes

• Verify shell size, insert arrangement, contact gender, and normal keying before mating.
• Use the correct crimp tooling for #22D signal contacts specified by arrangement 8B-35.
• Fully engage the triple-start threaded coupling with the mating MS27497 receptacle until the self-locking mechanism is seated.
• Mate only with MS27497 receptacles of the same shell size, arrangement, opposite contact gender (pin), and normal keying. Note: 8B-35 is Service Class M (sealed) — suitable for applications requiring environmental sealing.
• Do NOT attempt to mate with D38999/J599 Series III receptacles — MS27497 is a different standard and is not interchangeable.

Why Choose MS27497T8B35S

MIL-DTL-27497 Compliance

Choosing MS27497T8B35S ensures compliance with MIL-DTL-27497 (formerly MS27497) requirements for programs that mandate this specific standard. The straight plug geometry supports reliable cable-end interconnect with sealed signal capability, socket contacts, and normal keying for aerospace and industrial systems. Note: this connector is NOT a direct replacement for D38999/J599 Series III parts.

Ordering Information

Order by the MS27497 designation MS27497T8B35S. When requesting a quote, please confirm mating receptacle part number (pin contacts), shell finish class, contact plating, and required quantity. Note: 8B-35 is Service Class M (sealed); specify 8B-98 or 8B-02 for non-sealed applications.
