<p><strong>Backplane Connectors - Hard Metric, Standard</strong></p><p>The 1857990-1 is a type of hard metric backplane connector that is designed for high speed data transmission in applications such as computing, control systems, and telecommunications. This type of backplane connector is designed to provide a reliable connection between two or more boards in an electronic system. It is a standard rectangular connector with a single row of pins along one side of the mating halves.</p><p>The 1857990-1 has a number of unique features that make it suitable for a variety of applications. It is able to handle high speed data transmission rates up to 8 Gbps, and is designed with pre-drilled mounting holes to make installation easy. It is also designed to prevent EMI/RFI interference, ensuring that data is transmitted without interference or distortion.</p><p>The 1857990-1 features a standard IEEE 802.3ab compliant mating interface, with contacts arranged in a single row. The contact pins are designed with a unique spiral structure which provides a secure connection between the two mating halves. This type of backplane connector is designed to be used with printed circuit boards (PCBs) made from a variety of materials such as FR4, polyimide, and ceramic.</p><p>The working principle of the 1857990-1 Hard Metric backplane connector is quite straightforward. The two halves of the connector are mated using a simple push and slide technique. This ensures that the contact pins on the two mating halves are properly aligned and make contact with each other. The pins are then press-fitted into the mating interface and the two halves of the connector are tightly held together by the metal housing. This type of backplane connector is designed to prevent EMI/RFI interference from compromising the data transmission rates and ensure that the data is transmitted without errors or distortion.</p><p>The 1857990-1 is a cost-effective and reliable solution for a variety of applications such as computing, control systems, and telecommunications. It is designed to provide high speed data transmission rates up to 8 Gbps, and is designed with pre-drilled mounting holes to reduce installation time and cost. It is also designed to prevent EMI/RFI interference from compromising data transmission rates and ensure that the data is transmitted without errors or distortion. Its spiral contact pins are designed to provide a secure and reliable connection between the two mating halves.</p>
