Backplane connectors are specialized connectors used to interconnect PCBs, daughter boards, chassis sub-assemblies, and other interfaces. The 72478-1211LF is a specific type of backplane connector designed to support specific applications, and is worth a closer look. This article will first discuss the 72478-1211LF application field and working principle to gain a better insight into the capabilities of the product.

72478-1211LF Application Field and Working Principle

The 72478-1211LF is a high-performance backplane connector system designed to provide reliable connections between multiple PCBs, daughter boards, and chassis sub-assemblies. It features two rows of 2x40 Low Force contacts, providing up to 80 signal contacts and two power contacts. The connector is rated for 500Vac current, 5A current, and 1,000Vac/minute creepage distance. The connector features a CompactPCI version 3.0 compliant design and is compliant with the EN 60320-4-3 standard.

The 72478-1211LF is a combination connector featuring a combination of an electrical contact system, ventilated body, compression-mount contacts, and a 10-pole rated power contact. The contact system is constructed of a single contact finger, with a series of stamped and formed contacts, creating a 2x1 contact matrix. The electrical contact system offers a low contact force for easy connection and reliable signal transfer. The contacts are rated for 2A/contact and support voltages of up to 500Vac. The contacts are also rated for up to 1,000Vac/minute creepage distance.

The 72478-1211LF is available with three mounting options. The standard version is designed to be mounted on a 2.3mm profile (19mm between board layers), making it an ideal choice for CompactPCI 3.0 compliant applications. There is also an extended version which is designed to be mounted on a 4.3mm profile, offering increased durability and contact stability for high-temp applications. The third option is a slim version which is designed to be mounted on a 2.3mm profile for space-constrained applications.

The 72478-1211LF also features a ventilated body which helps to dissipate heat, an integral compression mount contact system which provides secure contact seating, and a 10-pole rated power contact for greater current capacity. The connector body is designed to fit into any PCB with mounting holes within the range of 3 to 6mm, and is compatible with standard 0.127mm edge connectors.

Overall, the 72478-1211LF is a versatile and robust backplane connector system that is designed to perform in a wide range of applications. It is designed to meet strict safety requirements and provide reliable connections. The connector’s combination of features provides excellent performance and reliability in a variety of applications, making it a popular choice for both industrial and consumer applications.
