ESQT-118-03-F-D-340

The ESQT-118-03-F-D-340 is part of the rectangular connectors family, specifically of headers and female sockets. As an electrical connector type, rectangular type connectors are a family of electrical connectors primarily employed for power, signal, coaxial and other interconnect applications. They can be divided according to their mating configurations, such as headers and receptacles, female sockets, and male headers. 

The ESQT-118-03-F-D-340 is a type of rectangular female socket. This specific connector uses a 3-pole female socket type, making it ideal for applications in which two power conductors have to be connected in parallel and have an additional third pole to be used as a signal in order to close or open the power circuits. 

When it comes to its main application fields, the ESQT-118-03-F-D-340 is often employed in different industrial, medical, or commercial equipment, as well as in any device where the power must be split in two paths and switched on and off using a third conductor.

In terms of its working principle, the ESQT-118-03-F-D-340 female socket connector is able to connect two power conductors through its two main poles, so they are connected in parallel allowing the same voltage to flow through both of them, while the third pole is used to switch the flow of current, so when the power circuits on both sides of the socket are open (no power flowing because of this third pole), neither the wrong voltage nor any current will flow through the connected parts. 

Apart from its suitable use for the previously mentioned applications, the ESQT-118-03-F-D-340 can also be employed in digital or analog circuits, as this female rectangular connector provides flexible connection solutions in order to ensure the reliable and safe transport of both power and signals. 

The benefits of this female rectangular connector type are mainly related to its size and associated weight, as its design of this kind of connectors implies a lower weight, a higher current capacity with a minimum voltage drop, as well as better heat dissipation, enabling it to offer better power connecting solutions to a greater number of applications. 

The ESQT-118-03-F-D-340 is indeed a connector of great reliability and efficacy, designed to provide safe and durable power-signal connections, as it provides an impedance matching, improved contact force retention and low voltage drop, which contribute to a successful operation of the device or application.
