This is a barrier screw terminal block designed to mount directly on a printed circuit board (PCB). It has 4 positions (holes) where wires can be secured in place by screws. The 7.62 mm pitch gives enough space for relatively thick wires, and the barrier design helps prevent accidental wire contact. It’s commonly used in power supply sections, amplifier outputs, LED strip hookups, and any place where a clean, solid wire connection to a PCB is needed. The tin-plated terminals offer good conductivity and corrosion resistance. For a low cost, this terminal block provides durable and reliable wiring connections in electronics projects.
