A terminal block is an insulated housing used to connect two or more wires that are arranged in a long strip. Either fixed or pluggable, the terminal block enables electrical conduction between joined terminals. Secure, well organized and semi-permanent wire connections can be swapped out easily.
The most common types of terminal blocks are screw-in, spring-loaded/spring-caged, European connectors/terminal strips, pluggable, and push-in, and networking and industrial applications are the most common.
Symmetry offers both fixed and pluggable terminal blocks from Digi International, a leading provider of IoT products and solutions.
