FGG.0B Quick Connect 4 Pin Plug - 9mm Outer Diameter

If you want the look and feel of aeronautical style quick-release connectors, this FGG.0B 4-pin Plug is an elegant and inexpensive alternative to official LEMO-C connectors. Although not mil-spec, they work and look great for DIY projects, keyboard builds, robotics, wearables, and more.

The connector snaps together smoothly and can disconnect only when the sleeve is pulled, which can be done one-handed with practice.

These connectors are popular for custom mechanical keyboard USB cables and many DIY applications.

Important: This is the plug for a two-part set; you will also need the compatible socket part to complete the connection. For a chunkier and less expensive wire-to-wire set, consider the YC-8 connectors.

Assembly notes: Using these connectors requires precise cable diameter (4.3 ~ 5.2mm) for the metal-toothed strain-relief grips to fit properly and delicate soldering skills. Assembly involves prepping the cable, tinning wires, soldering, heat-shrinking, and reassembling the connector.
