553-0210F is a dual-position LED indicator featuring a red LED in position 1 and a blank position 2, manufactured by Dialight for status indication and visual signaling applications. The device operates at 10 mA nominal current with a red LED luminous intensity of 8.7 mcd (typical) and a peak wavelength of 635 nm. The forward voltage for the red LED is 2.6 V (typical) at 10 mA, with a viewing angle of 60 degrees. The indicator is rated for continuous forward current of 30 mA maximum and operates over a temperature range of -55°C to +100°C, with a storage temperature range of -55°C to +100°C. This configuration is commonly used in control panels, instrumentation displays, and equipment status monitoring where a single red indicator position is required.
