PACKAGE DIMENSIONS

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 KWM-30881 series is 32.00mm (1.26") height 8 x 8 dot matrix display.

This series is suitable for use in single/multi-line message display, large area

graphics display and electronic games.

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