GX16 4 Pin – Aviation Plug Connector Panel Metal Mount Circular Metal Wire Connector Adapter Male Female Plug Socket (Pair of 2)

These are GX16 circular connectors, often called “Aviation Plugs” or “M16 connectors.” They are widely used in electronics and DIY projects (like 3D printers and radio equipment) because they provide a secure, locking connection that won’t vibrate loose. Here is a breakdown of how to work with these connectors: Anatomy of the Connector Male Panel Mount (Middle): This is the part you bolt onto a chassis or control box. Female Plug (Right): This is the part that attaches to your cable. Locking Mechanism: The female plug has a threaded “collar” that screws onto the male base to ensure a tight fit. Strain Relief: The back of the female plug has a small clamp with two screws to hold the wire in place and prevent it from pulling out of the solder joints.
