Flat Flex, Ribbon Jumper Cables are used in a wide variety of applications ranging from the transmission of serial data in computer networks, to providing power and grounding connections in robotics and automation systems. The FJH-15-D-78.75-4 cable is one such product, and this article will discuss the various applications and working principles of the cable.

General Features of the FJH-15-D-78.75-4

The FJH-15-D-78.75-4 is a flat cable composed of eight diffused wire pairs in a flexible PVC sheath. The overall shield is offered in two types: foil and braid. Each end of the cable is terminated with a 4-pin connector, which is connected to the cable via a 2.54 mm pitch connector. The cable boasts superior electrical performance, including a low capacitance and high DC resistance. It has operating temperature range of -40°C to +105°C, and its flexing life is up to 5 million cycles.

Application Fields

Due to its superior electrical performance and flexibility, the FJH-15-D-78.75-4 cable is ideal for use in applications that require flexing or vibration, such as robotics, automotive, medical, and industrial automation systems. Its flat nature makes it ideal for use in tight spaces, while its flexibility allows for a firm connection even in hard-to-reach areas.

In Robotics applications, the cable is used to provide power and ground connections between robotic components. In robotic arms, the cable can be used for controlling the movement of the robotic arms, as well as for transferring data between the various components. The cable\'s high flexing life allows for a reliable, long-lasting connection between the robotic components.

The cable is also used in automotive applications. It can be used to transfer data between engine control modules, as well as providing power connections for various sensors and components. It is also used for wiring and connecting components in electric vehicles, as the cable can withstand extreme temperatures and vibration.

Finally, the cable is ideal for medical applications, as its flexibility and small form factor make it suitable for use in medical devices such as endoscopes. The cable is also widely used in industrial automation applications, as its small form factor and superior electrical performance make it ideal for connecting components in factory automation systems.

Working Principle

The FJH-15-D-78.75-4 cable is composed of eight diffused wire pairs in a flexible PVC sheath. The sheath serves as a protective insulation for each wire, which is composed of multiple strands of copper. Each pair of wires has a different stiffness, which ultimately determines the flexibility of the cable. The wires are arranged in a flat pattern, allowing it to bend in any direction without kinking.

The cable is terminated with two 4-pin connectors, one on each end. The connectors are connected to the cable via a 2.54 mm pitch connector. The 4-pin connector contains two lines for power and two lines for data. One of the power lines is the common line, which carries the voltage applied to it. The other power line is the multiplex line, which carries the data signal.

When a voltage is applied to the common line, the multiplex line switches between high and low voltage, depending on whether the data is a 0 or 1. By switching the multiplex line between high and low voltage, the data can be transmitted over the FJH-15-D-78.75-4 cable. This process is the same for both receive and transmit signals, allowing for high-speed data transmission.

Conclusion

The FJH-15-D-78.75-4 is a flat cable composed of eight diffused wire pairs in a flexible PVC sheath. It is ideal for use in applications that require flexibility, such as robotics, automotive, medical, and industrial automation systems. The cable is terminated with two 4-pin connectors, which provide power and data connection between components. The power lines switch between high and low voltage, depending on the data signal, in order to transmit the data over the cable.
