DF3E-4P-2H(21)

DF3E-4P-2H(21) rectangular connectors—headers, male pins—are one of the most common connector types used in the electronics industry. They consist of a single plastic housing with four metal pins that are pressed or soldered into a mating socket to form a secure connection. The two numbers in the model designation, “4P” and “2H”, represent the number of contacts and the number of rows of contacts respectively. The last two numbers represent the gender of the connector: male for a pin and female for a socket.

The main application area for DF3E-4P-2H(21) connectors is for connecting two printed circuit boards (PCBs) together. They are widely used in electronics for many applications, such as those found in computers, consumer electronics, appliances, industrial control systems, and telecommunications. These connectors are also useful for connecting external devices such as disk drives, keyboards, pointing devices, and other equipment to a computer.

DF3E-4P-2H(21) connectors are designed to provide a reliable electrical connection between two components without interference from outside forces. The four metal pins are designed to make a very secure connection with minimal resistance when properly mated to a socket. The pins are typically plated with a thin protective coating of gold or tin which increases their conductivity and helps to prevent corrosion and other damage. The plastic housing helps to firmly hold the pins in place and provides a protective barrier from mechanical damage.

DF3E-4P-2H(21) connectors function by sending electrical signals from one printed circuit board to another. The pins are connected to the traces on the PCB, and when the connector is properly mated with its mating socket, each of the pins make electrical contact with the appropriate connection on the socket. This allows an electrical current to pass between the two devices. These connectors offer secure connections, perfect for applications requiring reliable electrical signal transmission with minimal resistance.

DF3E-4P-2H(21) connectors are some of the most commonly used connectors in the electronics industry. They are relatively easy to install and offer reliable electrical connections with good protection from outside interference. The pins have protective plating to further increase their durability and the plastic housing provides secure and reliable connections. With a wide variety of applications and features, these connectors are an ideal choice for connecting two assemblies together.
