DF3E-3P-2H(21)

Rectangular connectors, also known as board-to-board connectors, are a set of electronic connectors commonly used to join two printed circuit boards (PCBs) or a PCB and an enclosure. One type of rectangular connector, headers, male pins, are designed to transmit electronic signals from one device to another. The DF3E-3P-2H(21) is an example of such a rectangular connector.

The DF3E-3P-2H(21) is a three-row, two-position header that consists of a plastic housing and metal contacts. The header has a 3.5mm pitch, allowing it to fit within tight spaces, and it has a rated current up to 0.5A. The metal contacts make contact with the adjacent PCB, whereas the plastic housing provides insulation and structural stability for the whole connector.

The DF3E-3P-2H(21) offers a wide variety of applications. It is particularly popular in telecom systems due to its small size and superior signal transmission capabilities. It is also used in computers, cars, industrial computers, and a variety of other electronic devices. The header is compatible with most PCBs, making it an attractive option for designers who want a reliable connector.

The DF3E-3P-2H(21) header works according to the principle of elec­tro­me­chan­i­cal inter­face. This con­nec­tor oper­ates by mak­ing stable and re­li­able con­tact be­tween its metal con­tacts and the pins on the con­nect­ed PCB. When cor­rect­ly mated, the metal contacts bridge the gap between the two boards and allow the simultaneous transmission of electrical signals from one device to the other.

The DF3E-3P-2H(21) header is a reliable and robust connector that has been designed for long-term use. It has a high-pressure contact retention force to ensure robust electrical contact and is resistant to shock, vibration, and other environmental factors. This makes it suitable for high reliability applications.

The DF3E-3P-2H(21) header is an excellent choice for applications in which space is limited and reliable performance is essential. Its small size allows it to be used in cramped spaces while its integral metal contacts ensure reliable signal transmission. The header\'s robust design also makes it suitable for use in harsh environments. With its wide range of applications, the DF3E-3P-2H(21) is a reliable and versatile connector.
