DC Power Jack Female Connector PCB Mount

DC Power Jack Female Connector PCB Mount

This connector features a 2.1mm inner pin and 5.5mm outer barrel, compatible with most DC power plugs used in adapters and power supplies. It is designed to be soldered directly onto a PCB, offering a stable mechanical fit and reliable electrical contact.

The body is made of high-quality, flame-retardant thermoplastic, while the internal contacts are nickel-plated brass, ensuring excellent conductivity, durability, and corrosion resistance. The design typically includes three terminals — positive (center pin), negative (barrel), and a switch terminal (optional) that can disconnect internal power when an external adapter is plugged in.

This makes it especially useful in devices that support both battery and adapter power options, automatically switching between the two sources.
