Kingbright Auto Backlit Bar Graph LED Display, Green, 20 Segments, 5.08 mm Character Height, Through Hole, DC-20/20GWA

The Kingbright DC-20/20GWA Auto Backlit Bar Graph LED Display is a high-contrast electronic indicator featuring 20 green segments with 5.08 mm character height. Purpose-built for industrial, laboratory, and instrumentation applications, this model is optimized for panel-mount visualization tasks requiring accurate readouts of quantities, levels, or digital signals.

Its auto backlit design delivers uniform green illumination across twenty distinct display segments, providing granular visual feedback on measurement scales or process states. The high visibility is achieved with a 568 nm dominant wavelength LED, and the grey face paired with white colored segments maximizes contrast, even in challenging ambient lighting conditions.

With a through-hole mounting system, the DC-20/20GWA enables secure and conventional PCB integration, suitable for rugged manufacturing controls, laboratory testing setups, and electronic meters. The compact external envelope - 50.7 mm wide, 10.2 mm high, and 8 mm deep - makes it adaptable for space-limited installations without compromising display quality.

This bar graph array operates at a forward voltage of 2.2 V and supports a forward current of 30 mA per segment, with overall power dissipation capped at 75 mW. High efficiency and low current operation underpin its suitability for battery-operated devices as well as power-sensitive industrial monitoring instruments.

Environmental robustness includes an operating range from -40°C to 85°C ambient temperature, making it suitable for both laboratory and field deployments. The product is RoHS compliant, ensuring safety and adherence to international environmental standards.

Segment dimensions of 5.08 mm by 1.78 mm deliver excellent readability for control panels, process indicators, and level displays across manufacturing, automation, and HVAC environments. Its mechanically rugged construction supports end stackable configurations, allowing easy expansion or concatenation for custom multi-channel indicators.

The DC-20/20GWA from Kingbright is ideal for industrial process indication, laboratory analytical equipment, commercial electronics, and level monitoring panels. Its superior clarity, precise segmentation, and efficient operation meet the demands of modern electronic visualization.
