Super Bright Red 9.9mm (0.39-Inch) 4-Digit 7-Segment Common Anode LED Display for Dock Leveller Controllers
Product Overview
Introducing the Super Bright Red 0.39-Inch 4-Digit 7-Segment Common Anode LED Display—an industrial-grade numeric solution engineered for dock leveller controllers, instrument panels, and process indicators. Designed to prioritize durability, clear industrial readouts, and stable performance, this 4-digit display excels at showing critical dock leveller metrics: platform height (e.g., "0120" for 120mm), tilt angle (e.g., "0005" for 5°), or operation time (e.g., "1800" for 1800 seconds).
Its 9.9mm (0.39-inch) character height ensures readability from 1–2.5 meters (typical distance for dock workers operating controllers), while the 39.9×14×7mm form factor fits into compact dock leveller control boxes—no bulky redesigns required. The white segments on a black surface create sharp contrast with super bright red light (620-

Applications
While optimized for dock leveller controllers, this display also excels in:
Industrial Instrument Panels: Conveyor belt speed monitors (e.g., "0500" for 500mm/s), forklift height indicators (e.g., "0300" for 300mm), or warehouse door open/close counters (e.g., "1200" cycles).
Process Indicators: Factory production timers (e.g., "1800" for 30 minutes), temperature monitors (e.g., "0250" for 25.0°C), or pressure gauges (e.g., "0080" for 80kPa).
Home & Commercial Appliances: Large refrigerated warehouse controllers (e.g., "-180" for -18.0°C), commercial oven timers (e.g., "0600" for 60 minutes), or set-top boxes (e.g., "1200" for channel 1200).
