Detailed Product Description:

The 3-Pin Female Wire Connector is a cornerstone for any electronics project that demands a clean, secure, and easily-disconnectable connection. As a standard in modern prototyping, this component is designed with a precise 2.54mm pitch, making it perfectly compatible with common breadboards, protoboards, and a wide array of male pin headers. Its most popular variation, the JST-XH compatible socket, is a staple for a broad range of applications, from basic circuits to complex robotics.

The three-pin configuration is a versatile standard for managing power and signals. It is the de-facto connector for servo motors, with a standard pinout for ground, power (VCC), and a signal line. This organized structure eliminates messy wiring and ensures correct polarity, preventing costly mistakes. The connector's durable housing includes a friction-locking mechanism that provides a secure, reliable mating with the corresponding male header, protecting your circuit from accidental disconnections due to movement or vibration.

Often sold with pre-attached wires, this JST-compatible socket provides a convenient, plug-and-play solution that saves time and effort, whether you're a professional or a hobbyist. Beyond servo motors, its robust design and common electrical ratings (typically up to 3A at 250V) make it an excellent choice for connecting a variety of sensors, modules, and power supplies to microcontrollers like Arduino and Raspberry Pi. This robotics wiring harness component simplifies your project, making it more reliable, organized, and professional.

The 3-Pin Female Wire Connector is a JST-compatible 2.54mm socket that simplifies wiring in electronics and embedded systems. Commonly used with sensors, servo motors, display modules, or any 3-pin interface, it allows you to plug directly into standard male headers on Arduino boards, development kits, or custom circuits.

Each wire is pre-soldered and color-coded (typically black, red, yellow/white) for easy identification of GND, VCC, and Signal connections. This connector is a staple in DIY electronics kits and robotic control systems.
