FFC and FPC, also known as Flexible Flat Cable and Flat Flexible Connectors, provide a link between two adjacent PCBs (Printed Circuit Boards). This connection is used in multiple applications, ranging from consumer to industrial. The technology behind FFC and FPC allows for high-speed, reliable, and cost-effective interconnectivity between two or more boards. FFC and FPC (Flat Flexible) Connectors - Housings are the physical housings that the FFC and FPC cables are connected to, providing the necessary connections.

When selecting a FFC or FPC housing for your application, there are many important considerations. Factors such as customer requirements, construction type, cable size, and pitch all play a role in choosing the correct FFC/FPC housing for the job. A typical FFC/FPC Housings is made up of 2 parts, a receptacle and a hood. The receptacle is typically the mating part which is soldered onto the PCB and the hood is the over-molding component that secures the FFC/FPC cable into the housing.

The 4-487937-4 FFC/FPC housing is designed to support a flat flexible cable with a consistent width of 4.2mm and a 2.54mm pitch. The socket contacts are made of a high-performance alloy that can perform under extreme electrical and temperature conditions. This connector has a bayonet-style locking mechanism that ensures the secure connection between the FFC/FPC cable and the PCB.

When it comes to applications, FFC and FPC are used in a variety of fields, ranging from automotive, consumer electronics, medical devices, industrial automation, and more. It is ideal for use in applications which require a high-density, signal-carrying connection between two or more PCBs. Due to the flexibility of the cable and low insertion and release force, FFC and FPC is particularly suitable for applications where vibration is present.

The working principle of the 4-487937-4 FFC/FPC housing is simple. The flexible flat cable is inserted into the housing\'s receptacle and the outer shell contacts the metal pins on the receptacle. When the two halves are joined, the hood catches onto the bayonet-style lock on the PCB, securing the connection. In this configuration, the metal pins on the receptacle establish electrical contact with the cable. The pins also provide support to keep the cable securely in place once the connection is made.

In conclusion, the 4-487937-4 FFC/FPC housing is the perfect solution for applications requiring a reliable, high-density and cost-effective connection between two PCBs. The bayonet-style locking mechanism ensures that the connection will remain secure even in the presence of vibration, and its low insertion and release force make it easy to use. The metal pins of the receptacle create the necessary electrical contact with the cable and keep it securely in place.
