M20 3pin Waterproof Connector

Expanding on the 2-pin version, the M20 3-pin Waterproof Connector adds a third contact to support more advanced electrical setups. It is well-suited for three-wire control systems, grounded shielding, or applications where a separate signal line is needed alongside power—all without sacrificing the durability characteristic of the M20 series.
