JY27467T11B02PHN Circular Connector | MIL-DTL-38999 Series Equivalent

JY27467T11B02PHN Bayonet Circular Connector Plug, GJB599 Series I / D38999 Series I

The JY27467T11B02PHN is a bayonet-coupling circular electrical connector plug designed for aerospace, avionics, and industrial platforms. It conforms to GJB599A Series I requirements and is interchangeable with the MS27467T11B02PHN designation used in D38999 Series I supply chains.

This T-class plug features a threaded rear for backshell accessories, shell size 11, olive drab cadmium finish (B), insert arrangement 02, solder pin contacts (PH), and normal keying (N). The design supports EMI/RFI shielding, scoop-proof mating, and solder termination in a compact Series I package.

Product Features

• Conformant to GJB599A Series I (equivalent to D38999 / MS27467 Series I style)
• Interchangeable with cross-reference part number MS27467T11B02PHN
• Three-point bayonet quick-coupling for fast, vibration-resistant mating
• Threaded rear (T class) for GJB1784 / M85049 style backshell accessories
• Olive drab cadmium shell finish (B) for corrosion resistance and conductivity
• Solder pin contact configuration (PH) with insert arrangement 02 (typically 2 x #16 contacts)
• Five-key polarization with normal keying (N) for standard anti-mismatch mating

Part Number Breakdown

Related options: JY27467T11F02PHN uses electroless nickel finish; crimp versions omit H (e.g. JY27467T11B02PN); socket versions use SH contacts; alternate keying uses A–E. Confirm contact plating and service rating from the arrangement chart before harness design. There is no functional difference between JY and MS prefixes for form-fit-function mating within the same Series I family.

Compatible Applications

The JY27467T11B02PHN circular plug is intended for platforms that require compact, sealed bayonet interconnects with secure mating. Typical use cases include:

• Aircraft and helicopter wiring harnesses
• Avionics LRUs, radar, and communication equipment
• Ground vehicles and rugged electronic enclosures
• Shipboard and outdoor equipment requiring sealed circular connectors
• Industrial systems that standardize on GJB599 / D38999 Series I interfaces

Selection Guide

Installation Notes

• Verify shell size, insert arrangement, contact gender, finish, and keying before mating.
• Use the correct #16 solder contact process specified for arrangement 02; avoid overheating the insulator during soldering.
• Keep connector interfaces clean and capped when not in use to protect sealing surfaces.
• Select a matching T-class compatible backshell for the 0.5625-24 UNEF rear thread.
• Apply the recommended coupling engagement and, where required, use anti-loosening methods on accessories such as safety wire or thread-locking compound.
