The Green Connector PCB Mount 2-pin is a simple but very useful electronic component, widely used in power supply circuits and connections on printed circuit boards (PCBs). It is a type of pluggable terminal block connector, usually green in color, with two terminals (pins) that allow secure attachment of wires. These connectors provide a reliable way to connect and disconnect power or signal lines without soldering the wires directly onto the board. The 2-pin version is commonly used for DC input, power distribution, battery connections, or signal interfacing. The connector has two main parts: Screw Terminals – where you insert the stripped end of a wire and tighten it with a screw for a secure grip. Pin Headers – two metal pins that are soldered onto the PCB, ensuring firm mechanical and electrical contact. Typical pitch sizes are 3.5 mm, 5.0 mm, or 5.08 mm, depending on current rating and design. It can handle a wide range of voltages and currents (e.g., up to 300 V and 10–15 A in common models). The green color is standard in the industry for easy identification, though other colors exist. Its advantages include durability, reusability, and ease of maintenance, making it ideal for DIY electronics, Arduino/ESP projects, industrial control boards, and power modules.
