FTSH-145-04-SM-DH-A-C Application Field and Working PrincipleRectangular connectors are an essential part of any electrical system. From audio cables to power systems, these connections make up the backbone of most electrical systems. FTSH-145-04-SM-DH-A-C is a specific type of rectangular connector, part of the Headers, Male Pins category. Let’s explore its application field and working principle.Application FieldDue to its standard 0.8” pitch, the FTSH-145-04-SM-DH-A-C is mostly used for signal connections and can be found in a variety of applications. One of the most common applications for FTSH-145-04-SM-DH-A-C is in printed circuit boards (PCBs), where the connector is used as a signal connector to link multiple printed circuit boards, providing internal connectivity. The connector often looks like a solid plastic divider between PCBs, with one side of the connector plugged into a PCB and the other side plugged into a second PCB. FTSH-145-04-SM-DH-A-C can also be found in office electronics, such as printers and scanners. Here, the connectors are used to link power supplies, controllers, and other components used to control office electronics. Another common application field where you can find FTSH-145-04-SM-DH-A-C connectors is in home stereo systems. The connectors are used to link the various audio components to provide sound from one part of the system to the other, or to transfer data between the components.Working PrincipleThe FTSH-145-04-SM-DH-A-C connector consists of two main components, a housing and a pin. The housing is the part that provides the physical connection to the PCB. It consists of a plastic casing, in which the pins are arranged and held in place. The pin is a thin, flexible piece of metal that provides the electrical connection between the two components. On one end, the pin is inserted into the female portion of the connector. On the other end, it is inserted into the male portion of the connector, where it is held in place by a clamp. When two connectors are connected, the pins on each side touch, forming an electrical connection between the two components. This allows electricity to flow through the pins and between the components, providing an electrical connection. In addition to providing an electrical connection, the FTSH-145-04-SM-DH-A-C connector also provides protection from electrostatic and RF interference. The plastic casing helps to reduce the amount of RF interference that can pass through the connectors, while the clamps help keep the pins in place, preventing them from coming apart and thus protecting the electrical connection.To sum up, FTSH-145-04-SM-DH-A-C is a type of rectangular connector that is part of the Headers, Male Pins category. It is widely used in a variety of applications, such as printed circuit boards, office electronics, and home stereo systems. Its working principle involves the use of a housing and a pin, which provide the physical and electrical connections between two components. The plastic casing helps to reduce interference, while the clamps hold the pins in place to ensure that the electrical connection is secure.
