From the name, the DF9M-31S-1V(32) seems to be a type of rectangular connector. Rectangular Connectors are connectors made of receptacles, headers, and female sockets, that make wire-to-wire or wire-to-board electrical connection.The DF9M-31S-1V(32) is a two-row vertical surface mount connector, along with a few other variations. It is designed for high current application with about 1 milliohm of resistance and accommodating 6 to 32 circuits.To understand the working of the DF9M-31S-1V(32), it is important to consider the components used in it. It consists of a board-mounted receptacle and a header. The receptacle shuts the pins of the header when it mates, and electrical connection is then established. The header is a one-piece molded insulating unit made of high temperature and oil-resistant thermoplastic. It encloses the contacts and ferrules, which can be exactly mated with complementary female sockets. DF9M-31S-1V(32) is widely used to make reliable wire-to-wire and wire-to-board electrical connections. It is mainly used in electronic systems and automotive electronic wiring systems; or in medical equipment, home appliance wiring and information instrument wiring for various applications. As with many connectors, it requires a certain layout and design depending on the application it is being used in. In a wire-to-board application, the circuit board must have a cut-out area to accept the header which may or may not be the same size. The cut-out area should provide enough clearance, thread depth, surface space and contact-pin spacing. The contact-pin spacing should be the same as the spacing of the header pins. The design is important to secure electrical connection and contact between the board and the header. Additionally, mounting holes need to be provided in the circuit board so the header can be properly positioned and hold securely.For wire-to-wire application, the connector’s header is joined to a mating cable, usually by soldering. The contact points of the cable should be carefully stripped and the wires properly aligned in the header’s contact points. The connection can then be secured by soldering.The DF9M-31S-1V(32) is an efficient connector for making reliable wire-to-wire or wire-to-board electrical connection. It meets high current requirements, and can be assembled with a variety of cables and circuit boards.
