Flat Flex, Ribbon Jumper Cables: FJH-26-D-04.00-4 Application Field and Working Principle

Flat Flex, Ribbon Jumper Cables (FJH) are insulated, flat cables that are commonly used in aerospace and military applications. This family of cables offers an array of cable sizes and configurations to meet a variety of requirements. The FJH-26-D-04.00-4 is a double-layer, 26-conductor, 0.040” flat Flex jumper cable with an overall width of 0.156”. This particular cable is well-suited for airspeed and pressure sensors, and can be used in vibration and thermocouple applications. This article will discuss the application field and working principle of the FJH-26-D-04.00-4 cable.

Application Field

Flat Flex jumper cables are typically used in a variety of applications where size, weight, flexibility, and power transmission are important considerations. The FJH-26-D-04.00-4 jumper cable is well-suited for use in aircraft applications, where it can help create reliable, efficient connections between components located in tight spaces. This type of cable is typically used for airspeed and pressure sensors, thermocouple connections, and vibration isolation applications. It has also been found to perform well in a variety of industrial applications, including medical, automotive, and communications.

Working Principle

The working principle of the FJH-26-D-04.00-4 flat Flex jumper cable is based on the concept of “skin-effect” transmission. Skin-effect transmission occurs when an alternating current is passed through the conductor of a cable, creating an electron-rich “skin” on the surface of the conductor. This skin creates a low-resistance path for current to travel through the cable, ensuring better conductivity and efficient power transmission.The FJH-26-D-04.00-4 cable’s design maximizes skin-effect transmission efficiency by utilizing two insulating layers, both of which contain conductors. The inner layer contains 26 conductors, each insulated individually. The outer layer also contains 26 conductors, each insulated individually and between the inner-layer conductors. This double-layer design ensures a high degree of flexibility while also minimizing signal losses due to impedance.In addition to the double-layer design, the FJH-26-D-04.00-4 has a rugged construction that ensures long-term performance in demanding applications. The conductors are stranded and shielded with a copper-clad steel jacket, and the insulation is constructed of a high-temperature, abrasion-resistant polyethylene. These design features ensure that the cable can withstand vibration, temperature, and pressure changes, as well as other environmental factors.

Conclusion

The FJH-26-D-04.00-4 is a versatile, double-layer flat Flex jumper cable that is ideal for use in tight spaces. Its unique construction ensures robust performance in a range of applications, including aircraft, medical, automotive, and communications. Additionally, its double-layer design maximizes skin effect transmission, providing improved signal transmission and maximum conductivity.
