745925-2 Connectors, Interconnects

D-Sub Connectors

 As ubiquitous nowadays’ communication devices have become, they have a great demand for connectors to make devices sit down for communication and data transfer between them. D-Sub connectors, whose full name is “D-Subminiature connectors”, can be found on many computing and networking devices.

According to their capacity, D-Sub connectors can generally be classified into two broad categories –serial computer ports or peripheral ports which are also known as low-speed D-Sub connectors, and high-speed D-Sub connectors which are used for high-bandwidth applications. 745925-2 is a prevalent type of the latter, which is deployed on various computing devices especially for higher data rate tasks.

Application Field of 745925-2

745925-2 is mainly employed in computing and communication machines as connectors to facilitate high-bandwidth applications. It primarily supports both transmission and reception of data on integrated circuits through parallel contact patterns composed of 25 signal pins. And since it has a maximum signal rate of 6.25Gbps, resulting in an aggregate data rate of up to 25Gbps, 745925-2 is preferable for High-Definition Video (HD Video) data and Ethernet connections.

Working Principle

745925-2 consists of two complete sets of contact pins. The two opposite sides of connectors make sure that data transmission or reception could be performed safely and quickly, which is on the one hand ensured by parallel contact patterns to provide direct physical contact while on the other hand by the lockable screws that help fasten the two sides of connectors into a single one. So the work principle boils down to: when two cables are connected via 745925-2, the 25 contact pins create a parallel interface between them, presenting zero cross-talk at the maximum signal rate of 6.25Gbps.

Moreover, once the two connectors of 745925-2 are connected, they can detect automatically whether the two two ends are properly mated. Thus when signals are being transmitted, potential problems like signal loss and instability will be avoided and transmission quality will be improved.

Integral locking is also ensured with the lockable screws on the 745925-2 which provide additional mechanical stability to the connection when the cables are in place. That also offers increased impact to the insertion of cables and improves the reliability of the connection in the unstable environments.

Therefore, the 745925-2 provides a reliable, stable and efficient connection for communicating devices and is capable of delivering very high data rates. By pairing 745925-2 with other connectors of the same type, different devices are capable of connecting with each other and ensure a secure connection.
