Rectangular connectors consist of two components – a header and a receptacle. The ESQT-125-03-F-D-338 is a type of header component, or male socket, used to make a physical connection between electronic equipment and some external apparatus. Its application field and working principle are outlined below.

Application Field

The ESQT series is particularly suitable for high frequency or signal transmission applications. Its high performance levels are met thanks to its robust mechanical construction and use of highly specialized contact materials and insulation materials. The series is specifically designed for use in applications such as machine control and factory automation.

i)

In machine control applications, the ESQT is suitable for use in applications which require a secure and highly reliable connection between multiple pieces of electronic equipment such as a wiring harness connection. The series features a compact design to reduce the amount of space taken up in an industrial environment and also offers highly efficient signal transmission.

ii)

In factory automation applications, the ESQT is well-suited to applications that make use of large numbers of interconnecting cables due to its ability to reduce electro-magnetic interference (EMI). The design of the series also makes it ideal for applications which require a high level of performance over a long operating time due to its durable construction and contact materials.

Working Principle

The ESQT-125-03-F-D-338 is a male socket designed to connect to a Computer On Module (COM) or other electronic device via a female receptacle. This connection is secured using a continuous top-hat profile, which when mated tightly holds the two parts together and forms an extremely reliable connection with low levels of signal loss and low levels of EMI.

The header is supplied with a number of sockets on the top side, with the two pin version having six sockets in total. The top side of the header has three gold-plated contacts, which provide an electrical connection between the header and receptacle. The contacts are designed to minimize the amount of signal loss and EMI that occurs when the connection is established.

In addition to the gold contacts, the header also features a number of plastic protrusions on the bottom side. These protrusions provide an alignment and strain relief point when the two connectors are fitted together. The protrusions also ensure that the connection is held securely in place during operation.

Finally, there is a durable insulation material incorporated into the ESQT series which provides long-term protection against electrical and environmental interference.

The ESQT-125-03-F-D-338 is a highly specialized rectangular connector, ideal for applications in machine control, factory automation and other applications requiring a secure and reliable connection. This series has a number of features, such as gold contacts and plastic protrusions, which make it an excellent choice for those who require high performance and reliable connection over a long operating time.
