FFC & FPC connectorsFlat flexible cable (FFC) is a flexible cable with two rows of conductors in a flat package. Compared to traditional wiring systems, FFC offers easier installation, higher performance, and increased reliability and safety, which make it extremely popular in a wide variety of applications.FFC connectors are designed to provide electrical connectivity between FFC cables and electronic circuit boards. These connectors are typically composed of a metal socket and a plastic adaptor casing. The socket is specifically designed to fit the FFC cable, while the casing is designed to fit a hole in the circuit board. The socket and the casing are secured together with a metal pairing clip, ensuring a reliable electrical connection.Unlike FFCs, Flat Printed Circuit (FPC) cables are made from a flexible printed circuit material. The connectors for these cables are typically made from more durable materials such as stainless steel, although some plastic variants exist. The purpose of these connectors is the same as that of FFC connectors: to provide electrical connectivity between FPC cables and circuit boards.The 21FMN-BMT-A-TF is a type of FFC/FPC connector that is commonly used in a variety of application fields. This connector has a 1.27mm pitch and is composed of an outer casing and an inner socket. The outer casing features a positive latch with a twist lock mechanism that ensures secure mounting. The inner socket provides a reliable electrical connection between the cable and the circuit board.This connector is designed to provide improved stability and ease of assembly, as well as noise immunity for the connection between the cable and the circuit board. It is typically used in medical equipment, automotive electronics, consumer electronics, and industrial equipment.In terms of its working principle, this connector relies on a combination of the twist lock mechanism and the secure mounting provided by the outer casing. The inner socket contains the necessary contact points to establish electrical connection between the FFC/FPC cables and the circuit board. The casing helps ensure that the connectors stay in place, while the latch provides enough friction to keep the connector firmly seated in the circuit board. The contacts within the socket also provide the necessary electrical connection between the FFC/FPC cable and the circuit board.In summary, the 21FMN-BMT-A-TF is a type of FFC/FPC connector that is widely used in a variety of application fields. Its working principle relies on a twist lock mechanism and a secure mounting provided by the casing. The inner socket of the connector ensures that electrical connection is established between the FFC/FPC cable and the circuit board. This connector provides improved stability and ease of assembly, as well as noise immunity for the connection between the cable and the circuit board.
