The 311P409-3S-B-12 is one of the many D-Sub, D-Shaped Connectors - Housings available in the market. It is designed for board-to-board applications. It is commonly used in wire harnesses, cable assemblies, and junction boxes.

The 311P409-3S-B-12 is a three-way right angle PCB connector with a flange. It consists of two parts, a housing and an insert. The housing of the connector is made up of black polyester with a UL94V-0 flammability rating. It has a maximum current rating of 3.0 A and a wire-to-wire voltage range of 0.3 kVAC. It also has a wire-to-wire operating temperature of -25ºC to +85ºC.

The insert of the 311P409-3S-B-12 is made of zinc die cast for strength and durability. It is available in multiple terminals, including male/male, female/male, and female/female. Each terminal has a maximum contact current rating of 2.0 A. The typical contact resistance is less than 20 mΩ per contact. The insert also has a PCB retention force of 3.5 N/mm.

The 311P409-3S-B-12 is designed for use in wire harnesses, cable assemblies, and junction boxes. It is used to connect two PCBs together in a secure and reliable manner. The connector features a low profile design that can fit in tight spaces. The housing and insert are designed to be easy to assemble and install. The connector also offers secure mating with the use of a snap lock mechanism. This ensures secure connections and a longer service life.

The 311P409-3S-B-12 operates on the principle of electrical connection via connecting two terminals contact surfaces with two opposite spring cantilevers. The two connecting contact surfaces are made of phosphor bronze and are plated with gold to achieve high line pressure and ensure reliable contact. The spring cantilevers create a bridge between the contact surfaces and the PCBs, ensuring secure connections and high conductivity.

In summary, the 311P409-3S-B-12 is a three-way right angle PCB connector with a flange for board-to-board applications. It is made of black polyester and has a UL94V-0 flammability rating. The insert is made of zinc die cast for strength and durability. It is designed for use in wire harnesses, cable assemblies, and junction boxes and operates on the principle of electrical connection via connecting two terminals contact surfaces with two opposite spring cantilevers.
