IDEC AP series of pilot lights offer a simple, low cost solution to panel mounted indicating light needs. Available in four panel cutout diameters, with either dome or flat lenses, all units use an integral LED array with built in current limiting resistor. All IZUMI models mount with a locking ring that fastens from behind the panel, rendering them tamperproof from outside the panel. Termination is via solder terminals of various sizes, depending on the panel cutout. Available in 5V DC, 12V AC/DC or 24V AC/DC; there are also optional snap-on transformers and a DC-DC converter to support higher voltages.
