Rectangular connectors have been around for many decades and are commonly used in a wide range of applications in both digital and analog communication systems. The ESQT-140-02-G-Q-790 connector is a type of rectangular connector and is particularly suitable for use in applications requiring good electrical and mechanical characteristics. This article will discuss the application field and working principle of the ESQT-140-02-G-Q-790 connector.

The ESQT-140-02-G-Q-790 connector is a 2-row, 14-pin, right angle plug, unshielded, PCB mountable connector, designed for use in a wide range of applications. It has a contact pitch of 0.1 inch (2.54 mm), and features a blind-mating design, allowing it to be mated even without the need of a guide pin. It has a mating height of 9.5 mm (0.374 inch) and a current rating of 7 A per contact, with a maximum operating temperature of +105°C.

The ESQT-140-02-G-Q-790 connector is particularly suitable for use in demanding, high-current, medium-power applications, such as automotive, industrial, instrumentation, telecoms and datcoms equipment. It has excellent electrical performance characteristics, with a contact resistance of 20 mΩ maximum and an insulation resistance of 1000 MΩ minimum at 500 VDC. The contact retention force is excellent, with an initial force of 0.8 N per contact and a minimum of 0.5 N when mated. The connector is also designed to provide high levels of mechanical reliability, with a 25 mating and unmating cycle capability.

The working principle of the ESQT-140-02-G-Q-790 connector is straightforward and easy to understand. In brief, it works by allowing signals or power to be passed through from one section of the electrical system to another. The connectors provide electronic connectivity between two devices. Once the two connectors are mated together, power or signals can be transferred through the contact pins in the connector. The contacts are designed with gold plating to ensure a reliable connection and provide a low-resistance path for the current to flow.
