A 2.0mm wire-to-board terminal is a compact, high-reliability interconnect solution designed to establish electrical connections between wires and printed circuit boards (PCBs). With a 2.0mm pitch (spacing between terminals), it enables dense, space-efficient layouts, making it ideal for miniaturized electronics. These terminals typically feature a crimp-style design for the wire end, allowing secure mechanical and electrical attachment to wires (common gauge ranges: AWG 22-18) through precision crimping, which ensures low contact resistance and resistance to vibration. The board (board-side) often incorporates a male or female pin/socket interface, compatible with standard PCB headers or connectors for easy soldering or press-fit installation. Constructed from durable materials like phosphor bronze or beryllium copper with surface finishes such as tin or gold flash, these terminals offer excellent conductivity (≤5mΩ contact resistance) and corrosion resistance, suitable for harsh environments (-40°C to 105°C). Widely used in consumer electronics (smartphones, wearables), automotive systems (sensor wiring), industrial equipment, and medical devices, they balance compactness with robust performance, ensuring reliable power and signal transmission in high-density applications.
