ø1.75mm Terminal Pins Harwin ø1.75mm Terminal Pins resist accidental damage and are ideal for strong, durable, single-point connections in ultra-low-profile or offset-height board-to-board connections. Five lengths are available to vary the distance between mating PCBs, allowing wider tolerance gaps than many multi-pin connections. The Harwin ø1.75mm terminal pins are also suitable as PCB location pegs or grounding connections for stacked board configurations and are available with finish choices of hard gold or tin over nickel. The terminal pins are also compatible with SYCAMORE contacts.
