Description
The TDSL51.0 series are 13 mm character seven
segment low current LED displays in a very compact
package.
The displays are designed for a viewing distance up to
7 meters and available in high efficiency red. The grey
package surface and the evenly lighted untinted
segments provide an optimum on-off contrast.
All displays are categorized in luminous intensity
groups. That allows users to assemble displays with
uniform appearence.
Typical applications include instruments, panel
meters, point-of-sale terminals and household
equipment.
