FFC, FPC (Flat Flexible) Connectors - SFW4R-2STE9LF application field and working principle

Flat Flexible Connectors (FFCs) are the most common type of flexible connectors for electrical circuits that require a relatively flat and flexible connection. They are commonly found in a variety of applications, from consumer products to industrial equipment.

Application Field for FFC Connectors

FFC connectors can be found in a variety of applications where flatness and flexibility are important. These include:

• Computer peripherals like keyboards and mice
• Telecommunications equipment
• Data capture devices
• Mobile phones
• Networking components like switches and routers
• Industrial measurement equipment
• Medical diagnostic equipment
• Aircraft and military systems

For example, the SFW4R-2STE9LF is a FFC connector used in medical diagnostic equipment. It is a low cost, low profile, and highly reliable connector.

Working Principle for FFC Connectors

FFC connectors are designed to provide a quick and easy connection between two electrical circuits without soldering or mechanical fasteners. They are simple to install and are less vulnerable to vibration and temperature extremes than more rigid connectors.

An FFC connector typically consists of two parts. The first part is the socket, which is the female part of the connector and contains a series of Terminal Contacts made from a conductive material. The second part is the pin, which is the male part of the connector and contains a series of Signal Contacts made from an insulated material.

When the two parts are connected, the Terminal Contacts on the socket fit into the Signal Contacts on the pin. This creates an electrical connection between the two components. The contacts are usually held in place with locks and can be soldered in place if needed.

FFC connectors can also be used to connect shielded cables by the use of a Shielded FFC connector. The FFC connector has an internal shielding material that blocks EMI interference from external sources. This shielding material is electrically connected to a metal shield on the cable, providing an effective EMI shield.

FFC connectors are often used in environments where vibration or temperature extremes are present. The flexible contacts can withstand a certain amount of movement without breaking the electrical connection, making them suitable for harsh environments.

Overall, FFC connectors are reliable, low cost, low profile connectors that can be used for a variety of applications. The SFW4R-2STE9LF is a great example of an FFC connector that is perfect for use in medical diagnostic equipment.
