Rectangular Connectors - Headers, Male Pins

The DF3EA-4P-2H (20) is a rectangular connector-header, designed for the purpose of connecting a printed circuit board (PCB) to the mating boards or cables using pins. These connectors are designed to ensure reliable electrical contact and to provide for maximum flexibility with regards to their applications. The characteristics of this connector, and its usage in many different types of electronic products, allows it to effectively meet the needs of a wide range of applications.

Overview

The DF3EA-4P-2H (20) is a 4-pole single-row connector-header, designed and specified with a 2 mm pitch and a shrouded board lock design. It features two M3 tapped board lock holes in the connector housing, through which M3 mounting screws can be used for secure mounting onto a printed circuit board.

The connector-header consists of a housing in which the male pin terminals are held. The housing is constructed from 7830-55 polyamide (nylon) with a UL94V-0 flammability rating. The male pin terminals are constructed out of copper alloy 30 (copper-nickel-zinc), with gold plating over tin.

Applications

The DF3EA-4P-2H (20) Connector-Header is highly versatile and can be used in a range of applications. It is perfect for use as an input/output interface for applications such as computers, banking terminals, monitors, PC peripherals and more. It can also be used in applications such as medical electronics, automotive, and aviation. The durable construction and reliable electrical conductivity of the DF3EA-4P-2H make it an ideal choice for applications that require a secure and reliable connection.

Working Principle

The DF3EA-4P-2H (20) Connector-Header features two distinct types of male pin terminals, including a straight pin terminal and a right angle pin terminal. When the female socket is inserted into the connector housing, contacts from the female socket come into contact with the male pin terminals. This contact between the socket and the terminals creates an electrical path from one side to the other, allowing electricity to travel through the connector-header.

The male pin terminals are held in place by plastic clips which can be removed from the housing by pressing the clip release button on the connector housing. This makes the DF3EA-4P-2H extremely user-friendly, as it allows for simple and efficient insertion and removal of the female socket.

Conclusion

The DF3EA-4P-2H (20) Connector-Header is an extremely versatile and reliable connector-header, designed to make connecting board-level circuits easier and more secure. With its highly durable construction and reliable electrical conductivity, the DF3EA-4P-2H is perfect for the use in a wide range of applications, including computers, medical electronics, banking terminals, automotive and aviation. Its user-friendly design makes it a great option for anyone looking for a reliable and easy to use connector.
