Overview

Flat Flexible cables (FFCs) have become increasingly popular in recent years as they are generally smaller than traditional wiring methods, cost-effective, and have multiple applications in the industrial and consumer sectors. FJ-25-D-03.50-6 is a flat flex ribbon jumper cable specifically designed for highly current applications such as digital control boards, electronic control systems, and automation equipment. This article will look at the application fields and working principle of FJ-25-D-03.50-6 and how it’s different from other FFCs.

Overview of FJ-25-D-03.50-6

FJ-25-D-03.50-6 is designed for high current applications and is rated up to 30A per 1m. It is constructed from multiple layers of copper foils with a dielectric sub-layer of polyamide insulation, allowing transmission of multiple signals in one cable. The flexibility of the cable makes it ideal for applications that require frequent movement and bending. The flat flex has two footprints, a standard flat flex that measures 25mm by 6mm, and a reverse flat flex that measures 25mm by 10mm. It is shielded against electromagnetic interference with two 1mm foil shields and an overall braiding insulation sleeve.

Application Fields

FJ-25-D-03.50-6 is multi-layered, allowing multiple signal transmission paths in one cable which makes it ideal for use in digital control boards. This type of cable is also commonly used in computerized production lines to ensure stable communication between production machines. Moreover, FJ-25-D-03.50-6 can be used in automated equipment, where the flexibility of the cable allows it to withstand frequent movement and bending. Additionally, the small form factor allows for installation in tight spaces, such as in automotive electronics.

Working Principle

FJ-25-D-03.50-6 has two layers of copper foil that conduct electric current, while the first layer acts as the primary signal transmission path and the second layer acts as the return. The copper foils are insulated by a dielectric polyamide sub-layer, while the two 1mm foil shields reduce interference from external electromagnetic sources. Additionally, the cable’s flexibility allows for frequent movement and bending that does not compromise the cable’s performance.

Conclusion

FJ-25-D-03.50-6 is a well-designed flat flexible cable specifically made for higher current applications such as digital control boards, automation equipment, and electronic control systems. Its multi-layer design and shield insulation make it ideal for use in tight spaces and against external electromagnetic interference. The flexibility of the cable also makes it suitable for applications that require frequent movement and bending.
