Backplane connectors are specialized connectors which provide a way for the signal carriers to reliably send and receive data between two components separated within a chassis. The 74981-902LF backplane connector is one such piece of equipment, designed to provide reliable, high-speed data transfer in applications including Industrial Ethernet, Image processing, communications, managing storage, among others.

The 74981-902LF consists of a designed dual differential signal connector type, with reduced cross talk and magnetic field susceptibility, while providing a transmission rate of up to 3,072 Mbps. Its smaller than 1 mm footprint allows for improved design flexibility for application requiring tight spaces and its stackable design provides up to 300 contacts. It is designed to meet the rigorous environmental requirements while carrying signals and controlling overvoltage and inrush current. The 74981-902LF utilizes an insulation displacement contact (IDC) method for reliable and robust connections. In this method, the contact is located in a housing with the contact edge facing inward. The contact when sandwiched between the insulation displacement contacts will make an electrical connection as if it is passing through a gap in the substrate. This arrangement ensures that the connection is done with minimal movement of the contact edge.When applying the IDC principle to backplane connectors, external forces, including electrostatic discharge (ESD), stress created by gaps in the substrate, will cause a contact between the two pins, which may affect the performance of the device. The 74981-902LF employs a unique design that prevents the slightest movement of the contact edge, and provides reliable electrical connectivity. The 74981-902LF connector features an optimized pitch that enables reduced cross talk and reduced magnetic field susceptibility, making it ideal for applications that need high-speed data transfer. It also incorporates a mechanical release feature that permits easy install and removal from the circuit board, and eliminates the risk of shorting out the system due to an improper installation.In addition, the 74981-902LF has a superior insulation-displacement contact (IDC) method that makes connection to wires and cables easy and reliable. Unlike traditional wiring methods, which require the use of wire locking systems like soldering, the IDC method uses pressure locking contacts to securely engage wires. This reduces the chances of wire insulation failure due to contact wear or vibration.The 74981-902LF backplane connector is an ideal solution for applications requiring reliable, high-speed data transfer in extreme conditions. Its unique design prevents the slightest movement of the contact edge, and its optimized pitch enables reduced cross talk and reduced magnetic field susceptibility, making it suitable for applications requiring high-speed data transfer. Furthermore, its insulation displacement contact (IDC) method makes connection to wires and cables easy and reliable. All these features combine to make the 74981-902LF a reliable and robust connector to be used in applications requiring high-performance data transfer.
