Terminal Blocks - Headers, Plugs and Sockets - ELFH1G21G Application Field and Working Principle

Terminal blocks have been around for decades, and they are becoming increasingly popular as a way to manage wiring and connections in industrial and commercial applications. ELFH1G21G is a terminal block which combines the capabilities of headers, plugs, sockets, and jacks into one compact unit.Terminal blocks are ideal for applications where quick and easy wiring connection and disconnection are required. ELFH1G21G is a 3 pin header/socket combination that allows a device to be easily connected and disconnected from a power, data or signal source, without having to unplug or solder the wires. This makes it particularly useful for equipment which must be easily disconnected when not in use, or when undergoing routine maintenance.ELFH1G21G is not limited to power connections. It can also be used for transmitting signal and data in both directions. By disconnecting the block, both the sending and receiving devices are powered off, preventing any interference or unwanted signal from entering the system. This feature makes ELFH1G21G particularly useful for industrial applications, where the process should be safe and reliable.The principle behind the working of ELFH1G21G is quite simple. The socket part contains three pins – each connected to an electrical contact. The header part of the block has two rows of pins which are also connected to three contacts. When the socket is plugged into the header, the contacts on both parts make contact, creating the electrical connection. Once the socket is disconnected, the contacts on both parts break, breaking the connection.ELFH1G21G is rated from 0.5A to 5A and has a voltage rating of 30V. The terminals are enclosed in an insulating body, protecting them from moisture, dirt and other environmental factors. They are also rustproof, providing extra protection against corrosion. Additionally, the block is designed with a pushing system, which ensures a secure connection every time.ELFH1G21G is a great solution when you need to mix and match data and power connection easily. It is widely used in applications such as telecommunication, industrial automation, and medical electronics. For instance, ELFH1G21G can be used to quickly and securely connect a device to a data source or a power source, enabling the user to disconnect the device and its connecting wires from a safe distance.Overall, ELFH1G21G terminal blocks are an ideal solution for applications that require quick and easy connections and disconnections. They provide superior protection against corrosion, dirt, and moisture, and are built for use in a range of industrial, commercial, and electrical applications.
