DF9-21S-1V(20) is a series that belongs to rectangular connectors – arrays, edge type, mezzanine (board to board). It is a widely used connector whose structures can be found in most breadboards, adapter boards, and PC boards for all electronic applications.

DF9-21S-1V(20) meets the common 20 signal pin requirement for high-density board-to-board connection. Besides, it features insulation displacement contact (IDC) technology to ensure fast and easy connection with twin-axial cable. Its surface mount shield shell provides a robust shield in order to protect the connection against electrostatic interference.

The DF9-21S-1V(20) offering classifies as an edge type connector, which enables easy wiring on both sides of a PCB. It belongs into a whole range of connector designs that represent cost effective solutions when signal density requirements are involved. It is known for its ability to support high levels of electrical performance. Connector mating is achieved with simple linear insertion and the positive contact design ensures that mis-mate is prevented. The range also offers locking mechanisms, when needed, to secure mated connectors together.

The working principles of the DF9-21S-1V(20) are centered on its 20 pin configuration. That is, its double row design offers twice the signal density of discrete pin connectors with half the length and space. On each side of the board, narrow slots create the electrical connection when the double row female counterpart is mated. The electrical connection process starts by passing a single cable through the top row slot, then a second cable is passed through the bottom row parallel slot for reliable mating. Copper conductors in each cable are then forced in both rows, and creates an IDC style contact that allows currents to flow through. This double row female connector is then mated to the host male capture header.

The DF9-21S-1V(20) is an ideal choice for a vast range of applications due to its versatility. It is widely used in a myriad of different applications such as computer & communication, LED lighting, consumer electronics, automotive and medical. The connector offers an ergonomic connection that saves valuable space and ensures a secure connection.

The DF9-21S-1V(20) ensures a secure connection with a robust board retention that withstands in high vibration environments, and offers users extraordinary flexibility with minimal costs. With this in mind, the DF9-21S-1V(20) has become one of the most preferred connectors for applications that are demanding in terms of performance, size, and cost.
