Terminal Blocks - Headers, Plugs and SocketsTerminal blocks are interconnecting components with multiple terminations that allow electrical connections, signal transmissions, and data communications between two control devices. They facilitate testing, repairs and maintenance of electronic circuited, providing a mechanical structure to ensure electrical connections are made securely.Headers, plugs and sockets are three main types of terminal blocks. The purpose of a header is to allow a fixed connection, often for a group of terminals, such as a circuit board. Plugs and sockets help to create a temporary connection between two pieces of equipment and allow for a robust, reliable connection.The various edge module materials used when constructing the terminal blocks also contributes to their quality and performance. For example, stainless steel is an ideal material for use in the production of headers, as the metal is able to resist corrosion and temperatures. Plugs are typically made of hard steel or brass and sockets are often made of bronze.The 1557-510000 is a pluggable terminal block product for use with up to seven cables. It has two levels along the length of the device and the segmented housing is designed for convenient handling with a self-locking system to hold connections securely. The terminal blocks have UL94V-0 approved housing and contacts, as well as scoops and grooves for wire break off.The working principle of an edge module is simple, yet highly effective. When the plug or socket is inserted, it causes a reaction that pushes the contacts apart. This ensures that only the correct system connections are made and ensures that the plug or socket is securely in place. The connections are then tightened by means of a fastening screw and a round nut, creating a reliable connection with no slipping.Terminal blocks are an incredibly useful component and are widely used across many industries, from automotive and aerospace to food and beverage production. They come in a variety of sizes and a range of materials, from standard plastic components to stainless steel for increased durability. They provide reliable and secure connections and are easy to install and maintain. Their use in a wide range of applications highlights the importance of such components, helping to ensure power can be delivered to where it is needed.
