DF19G-20P-1H(56) Connectors, Interconnects

Rectangular Connectors comprise headers, male pins, and female sockets. The DF19G-20P-1H(56) connector is a type of headers, which comprises of two header parts, having a total of 20 contact pins. This particular connector is a product of Hirose, and is used in high-density applications, primarily. In this article, we will look at the application field and working principle of the connecter.

Application Field of the DF19G-20P-1H(56) Connector

The DF19G-20P-1H(56) series is used in 48 different configurations. The Hirose connector has a wipe length of 1.5mm and an insulation depth of 1.0mm. It is capable of housing low and high-frequency signals, and its electrical characteristics are based on the current industry standards. The Hirose DF19G-20P-1H(56) connectors are most commonly used in computing technologies, in particular as part of the I/O interface and memory. The device is also suitable for use in I/O and power distribution systems, particularly those found within automotive systems. In addition, the DF19G-20P-1H(56) connector is a popular choice in head-mounted displays, digital cameras, and other devices.

Working Principle of the DF19G-20P-1H(56) Connector

The DF19G-20P-1H(56) connector has a single row of contact pins, on either side of the socket. The pins are arranged in a 2mm pitch and are plated in either gold or tin plating. The contact pins on the male connector are made up of gold plated copper alloy, with an insulation made from polyphenylene ether (PPE). The female connector consists of an insulation made from high-temperature polyolefin (TPO), and the contact pins are plated with either gold or tin. Both types of contacts provide high electrical performance and a low contact resistance of 10 mΩ.

The connector is designed to function in what is known as mated and unmated conditions. In an unmated state, the contact pins on both the male and female components are unconnected. When the connectors are mated, a connection is established between the two devices. This forms a low-resistance electrical connection, allowing current to pass between the device. The construction of the DF19G-20P-1H(56) connector allows for a secure mating and a reliable connection, even when subjected to shock and vibration.

In conclusion, the DF19G-20P-1H(56) is a widely used header connector, mainly for high-density applications. Its features make it suitable for use in many types of electronic devices. It is capable of carrying both low and high-frequency signals and has a low contact resistance. When mated, the electrical connection is secure and reliable, and the connector can stand up to shock and vibration.
