The ESQT-129-02-M-5-375 is a rectangular connector that is part of the headers, receptacles, and female sockets category. ESQT connectors are designed for use with printed circuit boards and, depending on the specific model, are designed with varying contact sizes and configurations. The ESQT-129-02-M-5-375 is a 4 pin male surface mount connector with a 2.00mm pitch and a total length of 15.00mm. It features a rectangular black shell made of UL94V-0 rated flame retardant plastic. The male pins are wired in the board tail orientation and are made of gold plated brass to provide superior electrical and thermal conductivity.The main application of the ESQT-129-02-M-5-375 is in high-density circuit boards, wire harnesses, and ribbon cable assemblies. It is ideal for land grid arrays, jumper cables, and aerial connectors. The small size and 4-pin design allow for flexible and reliable connections in a variety of electronic and electrical components, such as embedded computer systems, memory and microprocessors, and electrical and communication devices. Additionally, the ESQT-129-02-M-5-375 is designed with a reliable lock, which ensures a secure and shock-resistant connection between the board and the connector.The ESQT-129-02-M-5-375 has an impressive working principle. The male pins are connected to the board by four contact points. Two of the contact points are connected to the external part of the connector, while the other two contact points are connected to the internal part of the connector. This connection is made via a gold-plated beryllium copper contact that is fixed to the head of the connector. The contact is inserted into a slot in the board and then secured with an epoxy adhesive layer that ensures the connection does not come loose over time. The connection between the board and the connector can also be reinforced with a mechanical lock.The ESQT-129-02-M-5-375 is a reliable and highly efficient connector. It can resist vibration, shock, and other factors that could affect its performance. Additionally, its small size makes it ideal for compact electronic circuits. The male pins are corrosion-resistant, heat-resistant, and have a low contact resistance, ensuring a reliable connection over a long period of time. Furthermore, the connector is easy to install and provides an effective connection between components in printed boards, as well as in wire harnesses and other small parts.
