The MS3476W22-41S is a mil-spec circular connector plug from the MIL-DTL-26482 Series II family. It is designed for harsh-environment aerospace, military, and industrial applications where vibration resistance, sealing, and reliable multi-pin connectivity are required.

It is a straight plug connector with a bayonet coupling mechanism and crimp contacts, commonly used in cable assemblies.

Key features include:

MIL specification: MIL-DTL-26482 Series II
Connector type: circular plug (straight)
Contact arrangement: 41 positions (shell size 22-41)
Contact type: socket (female) crimp contacts
Coupling: bayonet lock (quick connect/disconnect)
High environmental resistance (sealed against moisture, dust, vibration)
Operating temperature range: approx. -55°C to +125°C (or higher depending on variant)
Metal shell (aluminum alloy) with protective plating (cadmium/olive drab or nickel variants)
Used in aerospace, avionics, defense systems, and industrial control wiring
This connector is part of a broader military-standard ecosystem where interchangeable shells (like MS3470, MS3474, MS3476) ensure compatibility across different mounting styles and cable configurations.
