FX5-40S2A-DSA is a rectangular connector type that falls under the category of Arrays, Edge Type, Mezzanine (Board to Board). It is a connector whose primary purpose is to link two circuit boards together, forming them into one. This type of connector is commonly used in consumer electronics, such as gaming consoles, laptops, and smart phones.

The FX5-40S2A-DSA connector has a set of forty contacts that are arranged in two rows and twenty columns. Each row of contacts is made up of twenty Pitch 3.50mm contacts that are arranged in a cross connected pattern, providing ample contact points between the two boards. The contacts are soldered to a printed circuit board on the bottom and top of the connector, with a thermoplastic housing around it that protects the contacts from friction and unwanted debris. The contacts are plated with gold, which provides superior electrical conductivity and corrosion resistance.

The FX5-40S2A-DSA connector is also designed with an insulation displacement contact (IDC) system. This system eliminates the need for soldering as it creates a secure connection between the two circuit boards when the terminal tabs are inserted into the insulation. This allows for a quick and simple assembly process. The IDC terminal tabs have a 0.6-1.5mm pitch, and are made of phosphor bronze and tin-plated.

The FX5-40S2A-DSA connector has silver plated mechanical features that provide retention, anchoring, and polarization, meaning it will only fit in one direction. This prevents incorrectly connected boards from forming an electrical connection, which could cause a short circuit or electrical damage. The connector also includes a polarizing key and guide that ensures the connector is properly orientation during assembly.

The FX5-40S2A-DSA connector has a standard operating temperature range of -25 to +85 degrees Celsius, and a retention force of 8.5N per connector. It is rated for 500 mating cycles and can handle a voltage rating of 4.5k Vrms. That makes this a highly reliable and durable connector option.

In summary, the FX5-40S2A-DSA connector is a rectangular, mezzanine style connector that is designed to quickly and securely link two circuit boards together. Its IDC contact system eliminates the need for soldering, and its mechanical features provide retention, anchoring, and polarization. It is rated for a wide range of operating temperatures, and its 500 mating cycles and 4.5k Vrms voltage rating make it a highly reliable and durable option.
