Flat Flex, Ribbon Jumper Cables, FSP-21A-4 Application Field and Working PrincipleFlat Flex, or Ribbon Jumper Cables, are flat flexible cables that are used for a variety of applications and are generally referred to as flexible printed circuit cable assemblies. These cables are designed to replace traditional wire harnesses, providing a low profile solution for the connection of multiple components in limited spaces. The FSP-21A-4 is a flat flex cable commonly used in medical systems, automotive assemblies, industrial electronics and many other applications.The FSP-21A-4 is a 28 AWG (American Wire Gauge) multi-conductor flat flex cable with 4 conductors, a conductive cover and a shield. The cable is composed of four individual conductors that are laminated together with a conductive layer between them. This layer acts as an electrical shield which greatly reduces EMI (electromagnetic interference) and cross-talk between the conductors. It also helps to reduce stress on the conductors, increasing the durability of the cable.The FSP-21A-4 is constructed with two Kynar insulation layers with a 7.6mm thickness, providing excellent insulation between the conductors and prevent shorts. The wire is also UL rated and is flexible enough for use in tight spaces.The FSP-21A-4 is typically used in automotive systems, medical devices, industrial electronics and other applications where multiple components need to be connected in a limited area. The flat flexible design makes it ideal for applications where traditional cable assemblies would be too bulky or would not easily fit in the space available. The cable can also be used in applications where the environment may experience extreme temperature variations or humidity.The construction and design of the FSP-21A-4 provides an advantage in high vibration or shock applications as the flexible cable is less susceptible to electrical noise. The conductive layer also helps reduce the risk of shorts due to the increased electrical insulation.The FSP-21A-4 is typically installed by using a series of rivets or screws to secure the cable to the application. The conductor pins can also be crimped or soldered if required. The cable can be easily trimmed and cleaned for a secure and durable connection.Overall, the FSP-21A-4 is a reliable and versatile flat flex cable that can be used for a variety of applications. It’s low-profile design makes it ideal for applications where space is limited and its robust construction ensures a reliable connection. The cable is also relatively easy to install and its electrical properties make it suitable for applications with higher vibration or shock.
