Terminal Blocks - Headers, Plugs and Sockets

ELFR21130E is a kind of plug-in type terminal block for wire connection. It is widely used in the field of low voltage control system and electrical. It is a common terminal block in the application market and enjoys great popularity, for the low price and excellent quality.

ELFR21130E has various types to meet the connection and the installation needs of different products, just like approved products with headers have screw type, tear-apart type, pressure type, etc., with each of them providing different features.

Work Principle

ELFR21130E works by connecting the ground line of the plug head to the terminal. The terminal itself is a copper conductor, insulated by the material of the plug head. The insulated conductor passes a certain voltage, and the wire crossing the terminal is current-carrying. The electric current passes through the copper conductor, and the copper conductor of the terminal can provide the proper current-carrying capacity. The connection of the plug head and the terminal can prevent the short circuit of the cables.

The wires of the device are connected to the terminal head of the plug. This connection method will make sure that the connection between the terminals is very reliable and secure. The head of the plug can also provide the superior protection to the wires against rough surface or other external factors. The plug head has the ability to resist vibration and shock, and this is an extra feature that makes the device more reliable and durable.

Application Field

ELFR21130E is suitable for the application field of low voltage power distribution and signal transmission. It is suitable for the connection of the low voltage control system and the power system circuit in the project, as well as for the connection of wires in communication, remote control and measurement system. It can also be applied in the environment of high-frequency signal, such as the connection of signal lines of digital transmission system.

ELFR21130E is a multi-function plug-in type terminal block, with good applicability. It has strong wear resistance, high temperature resistance, flame retardant properties. It is safe, reliable and convenient to use, and it is a qualified product with good quality and reasonable price.
