The ESQT-128-03-LM-D-309 is a rectangular connector, classified as one of several types of headers, receptacles, female sockets, and other connectors. It is used to connect two circuits such as a power source and a load by providing a right-angle connection. As one of the most popular rectangular connectors, it is lightweight and has a good solderability.

The ESQT-128-03-LM-D-309 is a type of connector that relies on insertion forces to secure its electrical contacts. This type of connector operates on a 2.0mm pitch with a maximum current rating of 2.5A. With a maximum voltage rating of 250VAC/DC, the connector has the ability to conduct current in both directions. It is also capable of supporting a maximum temperature range of -40 to 105°C.

For mechanical strength, the copper alloy used in the housing construction has a high mechanical strength. It has a tensile strength of 880 N/mm2, a compressive strength of 1000 N/mm2, and an elastic modulus of 12700 N/mm2. It is also coated with an epoxy resin that ensures that the connectors are resistant to oil, moisture, chemicals and other corrosive materials.

The fabrication of the connectors includes two components, which are the Housing and the Connector Socket. The Housing is made from a copper alloy, which is then plated. This plating ensures that the connectors are resistant to abrasion and also adds to the aesthetical value. The Connector Socket is made of a copper alloy as well with a soft, non-conductive inner layer that ensures a good electrical contact.

The working principle of the ESQT-128-03-LM-D-309 is to provide secure connections between two electrical circuits. The connector utilizes insertion forces which allow the male prong of the connecting plug to be inserted into the female socket. This creates a connection with both prongs and the female socket. The electrical contacts are then securely held by the mechanical strength of the connector. The internal cavity of the connector also ensures that the plug and socket are held securely.The application field of the ESQT-128-03-LM-D-309 is mainly in the automotive, automotive electronics, factory automation, home appliances, and communication systems. These connectors are also used in a wide range of industrial machines and medical applications. As the connector offers an easy connection and a secured hold, these are preferred over more traditional connectors. The connectors can also offer the advantage of being able to be reused many times which makes them an economic solution for most applications.
