Reliable 4 Pin Female Socket Connector for Secure Connections

Upgrade your wiring projects with this 4 pin 0.1 inch polarized locking female socket connector. Designed for a secure fit and ease of use, this socket connector is perfect for machinery wiring, power supplies, and data connections. The polarized design ensures you never plug it in backwards, while the locking tab keeps connections tight and dependable.

Easy to Use and Compatible with Many Applications

Each polarized locking female socket connector fits standard 0.1" (2.54mm) pitch header pins—including single row headers found in many electronics and hobbyist projects. These connectors are fully compatible and interchangeable with the popular Molex KK series connectors, making them a versatile choice for repairs and custom builds.

Durable and Safe for Everyday Use

The crimp-style pins accept 22-30 AWG wire, allowing for quick, tool-free installation. The strong nylon 66 housing (UL 94V-2 rated) and tin-plated brass contacts provide excellent resistance to heat and wear, so your connections stay secure. The tabbed locking mechanism requires positive force to remove, preventing accidental disconnects—ideal for environments where vibration or movement could loosen a non-locking plug.
