JY3470A22-55PN MIL-DTL-26482 Equivalent Circular Connector with Shell Size 22 and Pin Contacts

The JY3470A22-55PN is a high-density circular electrical connector plug designed for aerospace, avionics, and industrial platforms. It features shell size 22, insert arrangement 55, pin contacts, and normal (N) keying for reliable mating in harsh-environment interconnect systems.

As a JY3470 series Class A plug, the JY3470A22-55PN provides a compact multi-circuit interface for signal and power interconnect. The pin-contact configuration mates with matching receptacles of the same shell size and arrangement, supporting secure coupling and environmental durability in tensioned-cable and vibration-prone installations.

JY3470 series high-density circular connector for demanding environments

Shell size 22 with insert arrangement 55 for multi-circuit interconnect

Pin contact configuration (P) for plug-side mating interfaces

Normal keying position (N) to support standard polarization and anti-mismatch mating

Class A shell finish for corrosion resistance in outdoor and industrial use

Suitable for aerospace, avionics, ground vehicles, energy, and industrial equipment

Compatible with matching JY3470 receptacle and cable accessories in the same shell size and arrangement

Related options in the same family may include socket contact versions (S), alternate keying codes, and matching receptacles with the same shell size and arrangement. Confirm mating pair, contact size, and finish before ordering.

The JY3470A22-55PN circular plug is intended for platforms that require compact, high-contact-count interconnects with secure mating and environmental durability. Typical use cases include:

Aircraft and helicopter wiring harnesses

Avionics LRUs, radar, and communication equipment

Ground vehicles and rugged electronic enclosures

Energy, railway, and industrial machinery systems

Shipboard and outdoor equipment requiring sealed circular connectors

Verify shell size, insert arrangement, contact gender, and keying before mating.

Use the correct crimp tooling and contact size specified for arrangement 55.

Keep connector interfaces clean and capped when not in use to protect sealing surfaces.

Apply the recommended coupling torque and, where required, use anti-loosening methods such as safety wire or thread-locking compound.

Select a matching backshell or strain-relief accessory for cable exit and environmental protection.

Choosing JY3470A22-55PN gives a clear part definition for shell size 22, arrangement 55, pin contacts, and N keying. That makes procurement, harness design, and field replacement more straightforward across aerospace and industrial programs.
