Terminal block selection guide

Terminal blocks, often called connection terminals or screw terminals, provide secure wire-to-board or wire-to-wire connections in a range of end applications. While a relatively straightforward component by their very nature, terminal blocks still have a number of design considerations to take into account.

Key mechanical specifications like the wire-entry orientation, wire-securing method, and module type will be important to note based on the design and intended use. Furthermore, key electrical criteria such as a terminal block’s current and voltage rating, pitch, and accepted wire size must be considered to ensure a proper connection and fit.
