Detailed Product Description:

The 4-Pin Female Wire Connector, a standard in modern electronics, is your go-to solution for creating clean, secure, and easily-disconnectable connections. This popular component, designed for JST XH compatibility, is a must-have for a wide variety of hobbyist and professional projects. Its key technical feature is the precise 2.54mm pitch, which ensures a perfect fit with the corresponding male header pins found on development boards, stepper motor drivers, and other components. The connector's durable housing and secure friction lock provide a reliable connection that resists accidental unplugs from vibration or movement.

Often supplied as a ready-to-use cable with pre-crimped and insulated wires, this connector saves you time and effort by eliminating the need for specialized crimping tools. The robust design is capable of handling significant loads, with a common current rating of up to 3A at 250V AC, making it a powerful choice for its compact size. Its versatility shines in its diverse applications. It is the de-facto standard stepper motor connector for Nema 17 motors used in 3D printers and CNC machines, providing a neat, organized way to manage power and signal lines.

Beyond motion control, this 4-pin JST XH socket is perfect for powering and controlling RGB LED strips, connecting complex 4-wire sensors, or creating custom battery packs. Whether you're building a robot, prototyping a new device with Arduino or Raspberry Pi, or repairing consumer electronics, this reliable wire-to-board connector delivers the perfect blend of performance, convenience, and durability, streamlining your wiring and improving the overall quality of your project.

The 4-Pin Female Wire Connector is a JST-XH compatible, 2.54mm pitch socket with pre-crimped wires ideal for plug-and-play connectivity in electronics projects. It is commonly used in Arduino and embedded systems for connecting components like I2C/UART devices, motor controllers, and LED modules.

This connector allows quick and solderless connections to standard 4-pin male headers, reducing assembly time during prototyping or hardware development. The durable plastic housing and high-quality wires make it suitable for both low-power and signal transmission.
