Flat Flexible Contacts (FFCs) are thin, flat wires that are used to connect electronic components together. They are ideal for use in many applications including data transmission, electrical power connections, and other electronic connections. The 487940-3 Contacts are a specific type of FFCs which are able to provide robust and reliable contacts, even in harsh environments. The contacts are used in applications where reliable connections need to be maintained while providing convenience in connecting and disconnecting the components.

The contact design has several features which make it more suitable than typical contact designs. The contact design includes a front and back barrel which are permanently connected together at the base. This creates a common connection to both the front and back barrels, providing improved reliability and making it easier to connect the contact to a PCB. Furthermore, the contacts have a double-locking mechanism for secure connections. This makes the contact more robust against damage due to connecting and disconnecting the components, as well as preventing the wires from disconnecting during operation. Additionally, the contact base includes a spring-loaded tab that securely holds the contact in place, even when there are high levels of vibration.

The standard contact design has two terminals that allow for two points of contact. This ensures more reliable connections, as it minimizes the risk of a separation between the two contact points. Furthermore, the contact design includes insulation, which prevents any electrical current from leaking and ensures consistent line termination. Additionally, the contacts are designed to support a variety of common board thicknesses and heights, which makes them very flexible and compatible with a wide array of applications.

The working principle of the FFC 487940-3 Contacts is quite straightforward. The contact barrels have a groove along the bottom which encompasses the contact finger when the connector is mated. When the connector is mated, the contact finger is pressed against the contact surface of the mating part. Then, when the mating parts are separated, the contact finger is released, thus breaking contact.

The 487940-3 Contacts are ideal for a range of applications, including data transmission, audio and video connections, electrical power connections, and automotive applications. The contact design is robust and reliable, and is able to handle connections in harsh environments without compromising performance. Additionally, the contacts are compatible with common board thicknesses and heights, making them ideal for a variety of applications. The contact design also makes it easier to connect and disconnect the components quickly and securely, making them ideal for applications where a fast connection is needed.
