Introduction
The 208273-2 backplane connector is widely used in the industrial markets for the connection of critical systems in embedded applications. The backplane connector is designed to make sure the signals and data of different components maintain their integrity during long-term transmission processes. This article explains the applications of 208273-2 backplane connector and its working principles.Application
The 208273-2 backplane connector is most commonly used in telecommunications systems, such as in those used for mobile systems. The backplane connector is also utilized for applications such as industrial controls, test equipment, processing systems, UPS systems, military application boards, and robotic control systems.The 208273-2 backplane connector is a wide variety of high-quality backplane connectors that offer reliable connections of industrial embedded applications while also providing a higher level of connector density, as well as improved electrical performance.DesignThe 208273-2 backplane connector consists of two parts: a male plug and a female receptacle. The two parts are designed to mate with one another, and to fit securely into an installation with a tool-less installation process. The connectors consist of numerous contact points that are arranged in a row along the length of the connector. The contacts are designed in such a way that they are not easily pulled out during operation. The plugs and receptacles are made up of polyetherimide (PEI) with UL94V-0 rated material. The PEI material offers an outstanding dielectric strength, high resistance to temperature, and exceptional vibration and shock absorption properties.Contacts
The connectors consist of two types of contacts: the contact polarization (PC) contacts and conventional (VC) contacts. The PC contacts are used to maintain the integrity of the signals, and it consists of two conductive surfaces in contact with each other. The VC contacts are used to provide high-reliability data transmission between components, and are designed with pin and socket contacts.The contacts are designed with gold-plated contacts, which offer superior electrical performance, and have a contact voltage range up to 250VAC/DC. The contacts are designed with an impedance in the range of 25 ohms and up to 200 ohms. Working Principle
The 208273-2 backplane connector utilizes a straight through design for its connections. This means that the contact-to-contact arrangement is straight in, straight out with no intervening or sharp bends. The arrangement ensures that the transmission and reception of signals and data between components are maintained during long-term operation.The contacts of the connector are designed to be function-tested prior to installation. This means that the contacts of the connector are tested for several functional parameters, such as the maximum signal rate, insulation resistance, contact resistance, electrical strength, and shear strength. This ensures that the contacts of the connector are designed to meet the highest standards of performance.The contact of the backplane connector are designed with a misalignment feature that is designed to maintain a reliable and secure connection between components of the system. This feature also helps to reduce the chances of system failures due to contact mis-alignment when used in industrial-scale systems.Conclusion
The 208273-2 backplane connector is an ideal choice for industrial and embedded applications. The connector is designed to provide secure, high-reliability data transmission between components for long-term operation. The connector is also designed with a misalignment feature that ensures reliable and secure connections between components of the system. The contacts of the connector are designed with gold-plated contacts which offer superior electrical performance, and a contact voltage range up to 250VAC/DC.
