Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts tin including indium tin oxide (ITO) sensor grids. The PTC requires one pin per X-line and one pin per Y-line. In the Self Capacitance mode, the PTC requires only one pin (Y-line) for each touch sensor. 461
