NU Series, Headers, Plugs and Sockets

Plug or receptacle header terminal blocks serve as versatile connection points for securing multiple wires to a circuit, cable, or power bus. These terminal blocks can be mounted on PCBs, DIN rails, channels, or panels, and may also be used in free-hanging or solder mount configurations. The mounting features of plug or receptacle header terminal blocks enhance their functionality and ease of use. These features may include board guides for secure PCB attachment, flanges for additional stability, latches and ejectors for easy insertion and removal, levers for quick wire termination, strain reliefs to prevent wire damage, and locks for added security. When selecting plug or receptacle header terminal blocks, one can choose from options that are UL certified and IEC rated, ensuring compliance with safety and regulatory standards. These terminal blocks are available in a range of current and voltage parameters, wire gauge compatibility, body colors, and termination styles. This allows engineers and technicians to precisely match the terminal block to the specific requirements of their application. In summary, plug or receptacle header terminal blocks provide a versatile and secure solution for connecting multiple wires to circuits, cables, or power buses. Their varied mounting features facilitate easy installation, while the availability of UL certification and IEC ratings ensures safety and regulatory compliance. The selection of terminal blocks based on current and voltage parameters, wire gauge, body color, and termination style enables precise integration into different systems and environments.
