Terminal blocks (also known as terminal connectors or screw terminals) are a widely used component in numerous applications to provide secure wire-to-board or wire-to-wire connections. Although a relatively simple component in the design process, there are still a variety of terminal block types and specifications to consider before making a final selection.
Key electrical specifications like a terminal block’s current and voltage rating, pitch, and accepted wire size are important to note to ensure a proper connection. In addition, key mechanical criteria such as the wire-entry orientation, wire-securing method, and module type will be factors depending on the application and intended use.
The CUI Insights blog post, “The Ultimate Guide to Terminal Block Selection” delves into these topics in greater detail by providing definitions and explanations of key electrical and mechanical considerations, safety ratings, and more to help engineers in the terminal block selection process.
