ESQT-140-03-H-S-309 Application Field and Working PrincipleRectangular Connectors - Headers, Receptacles, Female Sockets are one of the most common methods of interconnecting two or more electronic components within an electronic system. They provide a reliable physical connection and ensure that the signal transmission between the components remains uninterrupted and clear. Of these, ESQT-140-03-H-S-309 connectors are increasingly gaining popularity due to their superior performance and cost-effectiveness.This rectangular connector type consists of a header and a receptacle with 3.5mm pitch and 14mm axes. It has a polarization feature and four locating pins in the header. The external shell is made of anodized aluminum and designed for a snap-fit installation. The internal part contains two rows of short- and long-pitch connectors with three contours for increased contact density. The pins of the header and the sockets of the receptacle are made of high-quality copper alloys.The ESQT-140-03-H-S-309 has excellent electrical and mechanical properties, which allows it to be used in a variety of applications. The versatility of this connector makes it suitable for a range of applications, from light-duty to heavy-duty circuits. Its electrical performance and high current carrying capacity make it the preferred choice for applications such as switches, relays, circuit breakers, amplifiers, and motors.Moreover, the connector features excellent signal transmission and low noise, as well as superior temperature resistance. Its long operational life makes it the perfect choice for applications that require repeated use and long-term reliability. Its low cost and easy installation make it ideal for use in a variety of contexts, from safety and security systems to automotive applications.The working principle of the ESQT-140-03-H-S-309 is relatively simple: when the header and the receptacle of the connector are mated, the short- and long-pitch connectors of the receptacle make contact with the receiving pins of the header. This creates an electrical connection between the two components, allowing the signal to travel between them. The spring-loaded header ensures that the connection is maintained while the connector is in use.In conclusion, the ESQT-140-03-H-S-309 is an excellent choice of connector for a variety of applications due to its superior performance, low cost, easy installation, and long operational life. Its versatility and high current carrying capacity make it the perfect choice for high-performance systems, while its signal transmission and temperature resistance make it the preferred choice for safety and security systems.
