Terminal blocks are components used to establish electrical connections and are classified within the industrial category of connectors. As industrial automation advances and requirements for industrial control become increasingly rigorous and precise, the demand for terminal blocks has steadily risen. Driven by the growth of the electronics industry, the scope of application and the variety of terminal block types have expanded significantly. Beyond PCB terminals, the most widely used types include metal terminals, screw-clamp terminals, and spring-clamp terminals.
In 1928, Phoenix Contact invented the world's first modular terminal block. This innovation served as the prototype for modern terminal blocks and marked the company's first granted invention patent. Since then, Phoenix Contact has pursued innovation with passion, dedicating itself to developing diverse connection technologies and establishing a comprehensive system of electrical interface technologies; many of its product series have become industry standards.
