ESQ-128-69-S-D Application Field and Working PrincipleRectangular Connectors - Headers, Receptacles, Female Sockets are classified fundamental components in the electronics industry, and the ESQ-128-69-S-D is just one of them. Used in various electronic applications, they are valued for providing efficient transmission between circuits, boards, and devices. This article explores the application field and working principle of the ESQ-128-69-S-D. The ESQ-128-69-S-D is a connector with 2 to 24 contacts. It is made of a metal material with gold-plated contact pins and an insulation body. It is RoHS-compliant and flame retardant according to the UL 94 V-0 specification. With a temperature range of -40°C to +105°C, it provides reliable performance in high-temperature or moist environments. It has a 0.5A current rating, and a 7A AC/DC voltage rating. ESQ-128-69-S-D belongs to the “D” series in the ESQ series. It is widely used in the aerospace industry for various applications from vending machines to engine control systems. It is often present in-vehicle or portable electronic devices, such as televisions, navigation systems, or medical equipment. It is also frequently used in computer systems, industrial controllers, power converters, or protection relays. The ESQ-128-69-S-D offers snug connections that ensure electricity can flow freely and stable transmission of data. Such connectors also contribute to the stability of the system as a whole. It includes a couple of male and female single-sided and dual-sided header modules, which provide superior mechanical stability in the application of electronic devices.The working principle of the ESQ-128-69-S-D is based on electrical connections. To ensure that electricity can flow freely, the terminals of the connectors must achieve a precise contact. This is obtained through tiny metal contact pins, which fit precisely into their respective slot and have an electrical continuity with them. The headers and receptacles of the ESQ-128-69-S-D are specifically designed to create a high strength connection. These components consist of a pin contact with alignment grooves, providing tactile feedback when they are correctly connected. The connectors are designed to be durable, resistant to transportation vibrations and shocks, and still maintain contact integrity in rough environments. The most important thing about connecting electronic components using the ESQ-128-69-S-D is to make sure that it can support continuous electrical current while still performing its duty. To meet these requirements, the design features of the ESQ-128-69-S-D are carefully chosen. Besides having an insulation body, its contact pins are gold-plated, which improves their conductivity and rust-resistance. Its accurate design prevents short circuits and minimizes signal reflection. It is important to consider whether the ESQ-128-69-S-D is the best solution when looking for a connector for a given application. Such connectors can benefit a wide range of applications, as it offers reliable electrical connection provided its design and materials meet certifications such as the UL94V-0 standard. With the right specifications in place, the ESQ-128-69-S-D has the potential to provide efficient, reliable and secure connections.
