Rectangular Connectors - Headers, Male Pins

DF1B-4DP-2.5DSA(01) application field and working principle

DF1B-4DP-2.5DSA(01) is a connector type that belongs to the larger family of rectangular connectors. Known widely as headers or male pins, these connectors are highly versatile and used for numerous types of connection projects.The DF1B-4DP-2.5DSA(01) is a particular type of header that is used to connect wires and circuits together. It has a unique construction of four pins in a particular configuration, which makes it great for connecting a power supply between different systems. This type of header is also known as a "dual power pin connector."The application field of the DF1B-4DP-2.5DSA(01) involves connecting a power supply from one system to another. This is typically used in a wide range of electronic circuits and is a reliable and easy way to join power sources together.The working principle of the DF1B-4DP-2.5DSA(01) is quite simple. It consists of four pins that hold the connectors together. When the connectors are connected, the power is routed to the other system from the power supply mounted in the DF1B-4DP-2.5DSA(01). This power can then be used for electrical systems or components, depending on the power requirements of the device or system.The DF1B-4DP-2.5DSA(01) provides great electrical insulation, which is a key purpose of such a connector. This insulation ensures that the power routed to the other system remains safe, without the risk of shorting or causing a fire. As such, this type of header is a reliable way to join circuits together while still allowing the power to be safely routed to other systems.In conclusion, the DF1B-4DP-2.5DSA(01) is a type of connector belonging to the larger family of rectangular connectors, also known as headers or male pins. It is primarily used to connect power supply between different systems, providing great electrical insulation and allowing the power to be safely routed without risk of shorting or fire.
