Related options: JY27467T11F35PCN uses short PCB pins; JY27467T11F35PN uses removable crimp pins; B finish denotes olive drab cadmium. Confirm PCB pin length, hole pattern, and plating from the manufacturer drawing before board layout. There is no functional difference between JY and MS prefixes for form-fit-function mating within the same Series I family.
Compatible Applications
The JY27467T11F35PLN circular plug is intended for platforms that require compact, sealed bayonet interconnects with long PCB pin termination. Typical use cases include:
- Avionics modules and LRUs with board-mounted circular I/O
- Radar, communication, and control electronics
- Ground vehicles and rugged electronic enclosures
- Shipboard and outdoor equipment requiring sealed circular connectors
- Assemblies that need long PCB pins instead of crimp or solder-cup contacts

Installation Notes
- Verify shell size, insert arrangement, contact style (PL), finish, and keying before mating.
- Confirm PCB hole diameter, pin length, and soldering process against the manufacturer drawing.
- 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 when a cable accessory is required.
- Support the connector during board soldering to avoid mechanical stress on the insulator and contacts.
