TMM-110-04-SM-D-SM is a small, low profile, surface mount connector from the Rectangular Connectors – Headers, Male Pins series. Due to its small size and low profile design, it is popularly used in various electronic circuits. In particular, it is commonly found in the portable electronic device field, enabling small and light components to be quickly and easily attached to a board.

TMM-110-04-SM-D-SM consists of two main parts, a header and a pin. The header has two wire slots and four mounting holes. The pin’s body has two central contacts connected by a modified hexagonal contact bar. The contacts are made of high quality elastomer, which can be used for both low voltage and high current applications. The center of the pin is made of a phosphor bronze material that provides high contact reliability and good heat transfer.

TMM-110-04-SM-D-SM has two working principles. The first one is based on the mechanical fastening. The header part is soldered onto the PCB by hot bar soldering, while the pin part is soldered via hole soldering. The process is finished when the copper melts at the high point and the solder is connected to both sites. The second working principle of TMM-110-04-SM-D-SM is based on the electrical connection. It provides a low electrical resistance by connecting the two terminals at the metallic surface of the header and the pin. When we use a screwdriver to press the top of the pin down, the lower curved terminal at the bottom of the pin expands and firmly holds the header in place.

TMM-110-04-SM-D-SM has various applications in small electronic circuits. In communications devices, the connector can be used as power or we signals. It can also be used in space exploration for radio communication, as well as audio-video equipment for audio or video interconnections. In automotive products, the connector can be used to transfer power between the main and sub boards, or in car powering systems.

In addition to its various application fields, TMM-110-04-SM-D-SM also offers some advantages. The small design not only allows small and light components to be quickly and easily attached to a board, but it also provides excellent moisture protection, which is beneficial in terms of preventing damage due to water and dust ingress. Moreover, the locked design of the pin further enhances its safety. The combination of high frequency and high current insulation and reliable mechanical and electrical connection makes TMM-110-04-SM-D-SM an ideal choice for the Rectangular Connectors – Headers, Male Pins series.
