ESQT-140-03-M-Q-370 the application field and working principleThe ESQT-140-03-M-Q-370 is a variant of the rectangular connectors – headers, receptacles and female sockets. It is a high performance solution for the need of wireless and wired communication. Built into one package, this connector is designed with a high contact density and stability.The application field of the ESQT-140-03-M-Q-370 is especially specialized for use in medical, industrial, computing, telecommunication, consumer and automotive areas to meet the high speed data rate needs. It can also be used in wired connection of electronics device.Regarding its working principle, the ESQT-140-03-M-Q-370 is basically constructed from three main contact areas. The first two consist of two rows of pins which allows for positive locking and electrical contact. The third contact area consists of a locking tab which allows for mechanical locking and the corresponding conductivity between the two parts: the header and receptacle. As such, when the tab is pressed down, it creates positive contact and snaps into place. With the tabs being hidden in the receptacle, its reliability is further improved.The ESQT-140-03-M-Q-370 features two levels of shielding one being a metal shield which helps with shield interference from neighboring pins and the other being a keyed pin which helps with proper orientation of the cable assembly. Additionally, the keying feature of the connector ensures proper mating when connecting to any type of connector.Additionally, the ESQT-140-03-M-Q-370 are designed with redundancy as it has an open pin and a latch which securely hold the mating connector in place. Furthermore, its small size and high contact density makes it the perfect solution for today’s rapidly shrinking board spaces and narrow board designs. It also offers a high speed transfer rate and a comprehensive resistance to EMI/EMC performance which is often required in sensitive applications.The ESQT-140-03-M-Q-370 rectangular connectors – headers, receptacles and female sockets provide a reliable, cost effective way to make high speed data connections. It is an ideal solution for use in a wide variety of electronic applications and provides a durable, user-friendly alternative to traditional interconnect solutions.
