REMARKS : 1. The average luminous intensity is obtained by summing the luminous intensity of each segment and dividing by the total number of segments.

2. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE (International Commission on Illumination) eye-response curve.

3. Clean only by pure water, isopropanol, ethanol, Freon TF (or equivalent).

DESCRIPTION:

The KW1-1201 series is large single digit display in 1.20 inch (30.40mm) height

with right DP designed for accurate readable displays need to be viewed over

a distance.

This series is suitable for use in instruments, digital readout displays.

All devices are available as either common anode or common cathode.
