In a scanner, imaging bed, or detector assembly, the interconnect often sits where a standard rectangular connector is too large and a rigid pin is too likely to lose contact. The choice is not simply gold versus no gold. The contact pair, plating, spring material, temperature range, and termination method must work together to keep the signal stable over the life of the machine. A clear technical specification list helps the supplier evaluate the application instead of quoting a loose set of part numbers.
