Wilbrecht LEDCO (St. Paul, MN) has added symbol/legend marking options to its 100/600 series of panel LEDs for custom applications. Custom and universal symbols, such as battery light or oil level, can be used for easy identification. A simple stamp printing process allows a pictogram or short word to be printed in white or black ink on blue, green, amber, red and clear lenses. The LEDs can be selected in 3 intensities—High Efficiency, Daylight readable super bright, and super ultra-bright. Available in prototype to production quantities, the led indicators are built with standard DC LEDs or bipolar LEDs for AC applications. By adding a simple resistor, they can be operated at 5-60VDC or up to 240VAC.
