The SQW-120-01-F-D-VS-A-029 is one of the rectangular connectors. Headers, Recepticles, Female Sockets are its categories. It is featured with polarized plastic housing, brass gold plate contacts, 29-circuit array, and mounting in a mating board. It is so small that it can help save space for installtion.Application field:SQW-120-01-F-D-VS-A-029 headers, recepticles and female sockets are widely used for creating PCB systems with a minimum number of components. With its 29 circuits, it is ideal for the development of microcontroller- or microprocessor-based applications where time and cost efficiency are of great importance.It is usually used in the fields of robotics, security systems, medical equipment, industrial automation, electrical equipment, communications, instrumentation, IoT and others, wherein the connectors connect the board to the outside world.Working Principle:The SQW-120-01-F-D-VS-A-029 female sockets are constructed of a rectangular body which has multiple sets of pins located on the perimeter. The Connector is inserted into the mating board and secured with a securing arm on the bottom of the socket. The pins of the socket make contact with pin-holes of the mating board. The contact between the pins and the mating board is a matter of pressure, not solder. This contact creates the connection and the connection is made when the securing arm locks.The contact between the pins and the mating board is highly reliable. The thin layers of gold plated copper in the pins create a good connection that is less likely to be influenced by oxidation. This is possible because the gold layer on the pins and the pads of the board form a secure contact with a low contact resistance. The square shape of the pins and the mating board’s pin-holes ensures that the connection is properly connected and that there are no leakage currents.Conclusion:SQW-120-01-F-D-VS-A-029 is one of the rectangular connectors, which belongs to its categories: headers, recepticles, and female sockets. It is constructed with a rectangular body, multiple sets of pins located on the perimeter, polarised plastic housing, and brass gold plate contacts.
