Flat flexible connectors (FFC & FPC) are placed between two mating components of a device to create an electrical connection between them. This type of connector is typically used in consumer electronic products such as cell phones, video game consoles, remote controls, and GPS systems. FFC and FPC connectors have become a popular choice for these applications due to their small size, cost-effectiveness, and ease of installation. Here is a breakdown of one of the more popular FFC & FPC connectors— the SFW18S-2STE9LF— and a look at its application field and working principle.

Construction & Termination

The SFW18S-2STE9LF is a shielded FFC/FPC flat flexible connector designed for high-speed data and signal transfer. It features a high-quality 2-piece construction with a 2.00mm pitch, 18-contact, hybrid wire-to-board design with terminals that can be both soldered or crimped. The two leads of the connector are equipped with a shielded metal housing that helps reduce EMI/RFI interference and promotes reliable connection. The overall length of the cable assembly is 8.50 mm, allowing for flexibility and easy routing.

Terminations at each end can be made using male or female headers, depending on the needs of the application. Male headers feature a stepped design that ensures secure mating connection and are available in either straight or angled versions. Female headers feature a double row of pins in a square grid pattern and are widely used in high-density applications where space is at a premium. Both styles of termination provide reliable electrical and mechanical performance and are cost-effective.

Applications

The SFW18S-2STE9LF is the ideal choice for applications where high-speed data and signal transfer are required. It is commonly used in consumer electronics devices such as cellular phones, video game consoles, remote control devices, GPS devices, and more. The size, flexibility, and cost-effectiveness of these connectors make them popular for these types of applications.

Another application where the SFW18S-2STE9LF is often used is in the automotive industry. The 2-piece construction, shielded design, and reliable connection help ensure the safety and performance of automotive systems. The connectors are especially useful in applications that require vibration and shock resistance, which are common in the automotive industry.

Working Principle and Advantages

The working principle of the SFW18S-2STE9LF is based on the mating action of the two pieces. When connected, the two pieces are mechanically driven together, creating a reliable electrical connection. The advantage of this is that the connection is secure and reliable, with no risk of corrosion or wear. The connection is also moisture-proof, making it suitable for a range of harsh environmental conditions.

The SFW18S-2STE9LF also offers a number of other advantages, including cost-effectiveness, flexibility, and easy routing for applications where space is at a premium. The connectors are also small in size, making them suitable for use in compact and lightweight products.

Conclusion

The SFW18S-2STE9LF is a reliable and cost-effective FFC/FPC flat flexible connector. It is designed for high-speed data and signal transfer, making it the ideal choice for a range of consumer electronic and automotive applications. The two-piece construction and shielded design help ensure a secure and reliable electrical connection, while the connector’s small size and flexibility make it suitable for use in space-constrained applications. The SFW18S-2STE9LF is an excellent choice for any number of applications requiring high-speed, reliable connections.
