ESQT-128-03-L-D-400 isn\'t just a random string of letters and numbers, but an industrial electrical component used to connect various machines and devices together. This particular product from ESQT Corporation is a rectangular connector, known as a header, receptacle, or female socket. It\'s used to join two electrical components together in a secure and reliable manner.

Application Field
Headers, receptacles, and female sockets are used in a variety of industries, including automotive, medical, electronics, industrial automation, and robotics. They provide electrical connectivity between two or more electrical components, allowing them to power on, provide data exchange, control procedure results, and relay information back and forth. Their simple and reliable design makes them useful in many different applications.

Physical Description
The ESQT-128-03-L-D-400 is a 64-position header with a male-on-male configuration. It\'s constructed out of a dielectric base material that has been nylon 6-6 plastic. The total mounted height, or the distance between the top and bottom of the connector, is 0.45 inches (11.4 mm). It also has a board spacing of 0.080 inches (2.0 mm) with a minimum contact resistance of 20 milliohms.

Working Principle
This rectangular connector works by providing a mechanical and electrical connection between two or more points in a circuit. There are two main types of headers: the staggered version, which is also known as the dual row design, and the single row version. The single row version is widely used in lower power applications where there isn\'t a need for additional heat dissipation.

The ESQT-128-03-L-D-400 uses a dual-row design, meaning that it provides staggered contacts which gives it the ability to handle higher power. Staggered contacts provide more consistent contact resistance, lower wear, and longer life than their single row counterparts. The contacts themselves are two piece designs, made from phosphor bronze with a bright tin plate finish.

In use, header headers are typically soldered to the motherboard. Once in place, the latch on the header helps secure the connected wire or cable, while the key on the body of the connector helps keep it in place. The contacts on the header\'s steel pins make contact with the mating socket, allowing signals, power, or data to flow through the connection. The more contacts, the more potential data transfer speed.

Conclusion
The ESQT-128-03-L-D-400 is a rectangular header, receptacle, or female socket from ESQT Corporation. It can be used in a variety of industrial applications, from automotive and medical to electronics and robotics. Its dual row design allows it to handle higher power and data rates than single row connectors, while its two-piece contacts provide low contact resistance, long life, and little wear. Finally, the header is secured to a motherboard in place using a latch and a key.
