Backplane Connectors - Accessories

Backplane connectors, also known as backplane buses, enable the connection between multiple printed circuit boards (PCBs) for communication, data transfer, and power supply in electronic assemblies. The 025-1123-001 backplane connector is one of the most popular options for creating a stable connection for multiple components. Read on to learn more about the application field and working principle of the 025-1123-001 backplane connector.

Application Field of 025-1123-001 Backplane Connectors

The 025-1123-001 is a connector, developed by Harwin, for the backplane bus connection. This connector is suitable for the transportation of data signals in high density. It can be used in applications where a high pin density is required, such as communication, embedded computer and industrial automation. It also offers low profile height tolerant design for enclosure assembly and improved capacity for carrying power.

In terms of its PCB mounting application, the 025-1123-001 connector has 15.5mm width and 12.5mm length with 16 or 32 pins per row. And the current rating it can carry is up to 5A. It\'s RoHS compatible and is hot pluggable. The voltage it supports is up to 70V. Further, this connector is made of high-temperature thermoplastic and stamped phosphor bronze contacts to ensure safe and secure operation.

Working Principle of 025-1123-001 Backplane Connectors

The 025-1123-001 is, typically, a two-row board-to-board connector. It has two rows consisting of 16 pins each, providing a total of 32 pin contacts. The connector is equipped with a head-on-board design with a positive locking in place, which makes the connection between the boards secure. The mating portions are equipped with a tactile snap, making it audible and visible when the connector is mated and unmated.

The connector also features a positive locking system with a bayonet connection ensures for a secure mating. The pin and sleeve design guarantees the mating over a complete half-circle turn to ensure a secure connection. Furthermore, the dual-row pin system helps to eliminate the risk of shorting out connections. This increases the connector’s reliability in harsh environments.

The gold-plated contacts further help in creating firm contacts that provide high reliability and excellent electrical performance. The PBT housing material provides superior strength for the connectors in high-temperature applications. The solder tails are made of tin, and the contacts are precision machined for accurate mating and mating.

Conclusion

The 025-1123-001 backplane connector is a two-row board-to-board connector designed specifically by Harwin to provide secure connections with high pin density and electrical conductance. It has gold-plated contacts for reliability, and the pin and sleeve design makes it easier to mate and uncouple. Moreover, its housing material provides superior strength in high-temperature applications. If you think the 025-1123-001 is the right backplane connector for your applications, please contact qualified professionals to provide application-specific details and advice.
