Terminal Blocks - Headers, Plugs and Sockets: EFH02140 Application Field and Working PrincipleThe EFH02140 terminal block series is a range of professional-grade connectors, headers, and plugs for applications in a variety of fields. These terminal blocks are designed to provide reliable electrical connection for circuits used in a wide range of devices, such as computers, industrial machinery, and other technology-driven products. They are also used in automatic measurement and control systems for precise monitoring of current and voltage. The series of terminal blocks offers a number of features, such as flexibility, panel mountability, and varied current ratings.When selecting a suitable connection system for an application, the connector type, current rating, and voltage rating should be taken into consideration. The EFH02140 series is suitable for a range of current ratings from 0.5A to 100A, and voltages up to 500V. The main range comprises a variety of type 1, type 2, and type 3 terminal blocks, all of which can be selected depending on the requirements of each application.The EFH02140 series is available in both soldered and screw terminal types, and are either fitted into printed circuit boards (PCB) or mounted on a panel. Each type features a unique design which enables the user to taste and fit the connector without affecting its performance. The terminals are designed with a permanent contact that is resistant to vibration and shock, thus providing superior reliability in harsh environments. The terminal blocks are also designed with over-moulded hard insulation to protect the internal components from dust, moisture, and other particles that could interfere with the quality of the connection. They also feature a high-temperature resistant dielectric material that prevents metal corrosion and improves insulation properties.When installing a standard terminal block in a PCB, it is important to select the right strain relief and insulation system. The most common methods used are the use of a PUSH-IN connection (PICC) and a screw terminal connection. The PUSH-IN connection system uses a spring-clamp for the connection which gives a secure contact and easy installation, while the screw terminal connection system uses a screw for the connection, which provides a good electrical and mechanical connection.When using the EFH02140 series in a panel mountable application, it is important to ensure that the terminal block is secured firmly to the panel. It is ideal to use a flat spring screw or M4 nut for this purpose, as this provides a secure connection. Also, the wires should be cut to the right length, allowing for sufficient space between the connector and the panel, and the mating part should be twisted before being installed onto the panel. The EFH02140 series operates according to a simple working principle: when a connection is made between two terminals, the current flowing through them creates a magnetic field. This magnetic field then causes the current to switch to the opposite terminal, creating a closed loop and delivering an uninterrupted current flow.In conclusion, the EFH02140 series of terminal blocks offers a range of connectors, headers, and plugs suitable for applications in a variety of fields. With its flexible design, panel mountability, and varied current ratings, the terminal blocks provide reliable electrical connection for a broad range of circuits and devices. The series of terminal blocks is designed with an easy-to-use connector system and features a permanent contact that resists vibrations and shocks, as well as a high-temperature resistant dielectric material for improved insulation. Additionally, the terminal blocks operate according to a simple working principle that allows for a continuous current flow when the terminals are connected.
