The Para Light A-3570SR is a 5×7 dot matrix red LED display from the 3570 series. With 35 LED dots in 5 columns and 7 rows it shows letters, numbers and symbols. When choosing a dot matrix display the key dimension is the dot (pixel) size rather than the display size in inches, and in the 3570 series each dot is 3 mm in diameter. Its through-hole design makes it a common choice for control panels, lift indicators and meter displays.
