Rectangular Connectors - Headers, Receptacles, Female SocketsESQT-122-03-M-D-313 application field and working principleRectangular connectors are important connecting elements in the transmission and control of electric signals. The product selection of rectangular connectors is vast and they are available in several formats such as headers, receptacles, female sockets, and more. In this article, we will focus on the ESQT-122-03-M-D-313 application field and working principle.The ESQT-122-03-M-D-313 is a two-part rectangular connector from Samtec. It is a female header that features two rows of female contacts in a wipe-contact style configuration and a mated vertical 21- and a 5-pin count. These contacts are made from copper alloy. The header features two guide posts and a press fit retention status spring clip. This clip ensures proper mating of the connector with its complementary mating part. The ESQT-122-03-M-D-313 feature a current and voltage rating of 1.5A and 300V respectively. The operating temperature can range from -55℃ to +105℃. The insulation resistance at 100Mohm and dielectric withstanding voltage of 1000V AC. Due to these features, the ESQT-122-03-M-D-313 is widely used in a variety of applications like medical, industrial, consumer electronics equipment, automotive, computer, audio etc. It is also used as an interconnect solution for high-speed communication applications such as Ethernet, CANBus, and 10GBASE-T Ethernet. It is especially suitable for automated processing applications, such as SMT and through-hole board-to-board assemblies.The ESQT-122-03-M-D-313 working principle is based on the wipe-contact design. Here, two parts, the resilient contact and the contact housing, feature metal contacts that snap together to create an electrical connection. The contact housing features a channeled surface that allows movement between the parts. As the parts are being mated, the contacts move towards each other and experience contact wiping. During this process, the contacts are cleaned and freed from any dirt, resulting in a stable and reliable connection. The wiping action also compresses the spring-loaded contacts, ensuring a perfect seal with the mating part. In addition, the ESQT-122-03-M-D-313 also feature a press fit retention status spring clip that ensures adequate force to make a secure electrical connection. This feature makes the ESQT-122-03-M-D-313 suitable for use in even the most extreme vibration and shock environments.The ESQT-122-03-M-D-313 is a highly reliable rectangular connector that allows efficient transmission and control of electrical signals. It is easy to install and manage, which makes it a popular choice for many applications. Its versatile design and high performance make it the perfect option for those seeking a reliable, efficient, and cost-effective connection solution.
