Related options: JY3470L1832PN / MS3470L18-32PN uses electroless nickel finish (L); socket versions use S contacts; alternate keying uses A–W positions as applicable. For mixed #16/#20 contacts in the same shell size, see arrangement 18-30 (JY3470A1830PN). There is no functional difference between JY3470 and MS3470 prefixes for form-fit-function mating within the same Series II family.
Compatible Applications
The JY3470A1832PN narrow flange receptacle is intended for platforms that require compact, environment-resistant bayonet interconnects with high-density #20 signal circuits. Typical use cases include:
- Aircraft and helicopter wiring harness panel interfaces
- 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 GJB598 / MIL-DTL-26482 Series II interfaces

Installation Notes
- Verify shell size, insert arrangement, contact gender, finish class, and keying before mating.
- Use the correct crimp tooling for #20 contacts specified by arrangement 18-32.
- Mount the narrow flange securely to the panel and keep sealing surfaces clean.
- Cap unused receptacles to protect the interface when not mated.
- Select matching plug and cable accessories compatible with MIL-DTL-26482 Series II / GJB598 Series 2 interfaces.
