Terminal Blocks – Headers, Plugs and Sockets, EM211804H Application Field and Working Principle

Terminal blocks are a type of joining technology that are used mainly in the field of electrical engineering, to firmly connect together two different electrical lines. The EM211804H is a combination of header and plug and socket terminal blocks, or a hybrid connector.

Applications

The EM211804H is a widely used connector in the industrial and electronics industry, both in buildings and in applications. It is mainly used for two-wire circuit and network because of its simple structure and fast connection. This electrical connection is generally used in motor controllers, machine control, building systems, and automation systems. Additionally, due to its stable connection and ability to protect wiring, it can also be used in industrial manufacturing equipment and devices.

Working Principle

The EM211804H terminal blocks consist of two components, a header and a plug-socket, which are connected using screws or jumpers. The header and plug-socket are connected to by way of a two-contact lever, and the contact between the header and the plug-socket is made by two different ways. First, the header has a protruding contact that fits into the inner cavity of the plug-socket. Then, a nut is used to tighten the contact further, by screwing it onto the bolt of the header. After that, the electrical connection is made and the current can flow.

The EM211804H terminal block has a plastic insulation sleeve on the top, with a conductive surface. The grounding contact in this terminal block is connected to the end of the plug-socket, and then attached to the ground terminal. This helps to protect the cable from parallel external electric fields, and ensure the safety of the user.

Advantages

The EM211804H connector has many advantages over other connectors in the same category. Its compact and lightweight design allows for versatile mounting on different surfaces. The double-contact lever supports fast and reliable connection between the header and connector. Moreover, the usage of screws or jumpers brings good elasticity and flexibility when vibration occurs. It also has a good insulation shell that provides IP20 protection rating and anti-static protection. Also, its venting design avoids rapid temperature rise, and this makes the EM211804H suited for the high temperature working environment.

Conclusion

The EM211804H terminal blocks are widely used in industries as well as buildings because of its versatility and flexibility. It offers fast and reliable connection for two-wire circuits, as well as protection against external electric fields. The lightweight design and good insulation shell make the EM211804H a preferred choice for many industrial and electronics applications.
