Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) have a wide range of applications, and the DF9B-21S-1V(20) connector is no exception. This type of connector is designed for low current, reliable, and secure communication between two circuit boards, making it ideal for a wide range of applications. A brief overview of its various features and its working principle is given below.

Design and Features

The DF9B-21S-1V(20) is a mezzanine form factor connector that features a 21-pin array with a PCB edge connector. It also has a locking mechanism that prevents accidental disconnection and provides reliable connectivity between two circuit boards. The connector is designed to have a low profile in order to facilitate routing of wires and cables. It also features an anti-snag design to prevent bending and breaking of wires and pins.

The contact pins of the DF9B-21S-1V(20) connector consist of gold-plated steel for superior electrical contact and reliable connection. It also features a wiping-type contact system that increases the connector\'s mating durability and limits insertion force. This ensures that the connector can hold up against vibrations and shock without getting damaged.

Applications

The DF9B-21S-1V(20) is ideally suited for small-scale, medium-current applications that require reliable and secure connectivity between two circuit boards. It is typically used in electronic products and devices that require a low profile, such as tablet PCs, media players, mobile phones, and medical devices. It is also used in communication systems, automotive electronics, industrial machinery, and other applications where reliable, low-profile connectors are needed.

Working Principle

The working principle of the DF9B-21S-1V(20) connector is fairly straightforward. When connected to a power source, the pins on the connector make contact with the corresponding pins on the other board. This creates an electrical connection between the two boards, allowing for data transfer. The contacts are designed to have a low resistance, reducing power loss and providing a reliable connection.

The connector also has a locking mechanism that ensures that the connection between the two boards is secure. This prevents accidental disconnection and ensures that the connection is reliable and stable. The locking mechanism also prevents vibrations and shock from causing damage to the connector or disrupting the data transfer.

Conclusion

The DF9B-21S-1V(20) is a low-profile, high-performance mezzanine form factor connector with a large number of applications. Its design features allow it to be used in a wide range of applications, from consumer electronics and medical devices to communication systems and industrial machinery. It also features a reliable locking mechanism that allows it to securely connect two boards, providing reliable and stable connectivity for data transfer.
