Introduction

The DF4-12PA-2R28 is a rectangular connector from the Board In, Direct Wire to Board family of rectangular connectors. It is designed to wire individual signals or power from a printed board directly to another printed board. The DF4-12PA-2R28 features a rectangular body, a two-row connector, and two polarizing keys to prevent mismating. This connector type is most commonly used in consumer and industrial applications.

Application Field

The DF4-12PA-2R28 is a widely used connector type for wiring individual signals or power through a printed circuit board (PCB) directly to another PCB. It is used where specific ports are available for connecting different types of signals, such as signals from switches, sensors, actuators, cameras, and other electronic components. This connector type is commonly used in the fields of medical, consumer, and industrial electronics, as it offers a reliable connection that does not require soldering. Furthermore, its small size allows for design flexibility and board serialization.

Working Principle

The DF4-12PA-2R28 is designed to be inserted into two receptacles located on two separate boards. It precludes the need for direct soldering of the pins onto the boards. Instead, once the mating surface of the connector is inserted into the receptacle on the board, the internal surface of the receptacle contacts the connector, establishing electrical contact. This allows for reliable electrical contact on both sides of the connection.The pins on the DF4-12PA-2R28 provide electrical connection between the two boards without the need for soldering. The pins are rated for 28 AWG to 14 AWG wire sizes, and are designed to securely hold the inserted wires in place. Besides providing electrical connection, the connector also prevents physical contact between the two boards connected by the pins, thus reducing electromagnetic or radio-frequency interference.

Conclusion

The DF4-12PA-2R28 connector offers a reliable connection between two printed circuit boards without the need for soldering. It is a widely used connector type for connecting individual signals or power through a PCB, and is commonly used in medical, consumer, and industrial electronics. The pins on the DF4-12PA-2R28 are designed to securely hold inserted wires in place for reliable electrical contact on both boards. Additionally, the connector also provides protection from electromagnetic interference.
