Small-Size Super Bright Red 5.5mm (0.22-Inch) 6-Digit 7-Segment Common Cathode LED Display for Industrial Equipment Control Panels

Product Overview

Introducing the Small-Size Super Bright Red 6-Digit 7-Segment Common Cathode LED Display—a miniaturized, high-reliability solution engineered for industrial equipment control panels, instrument panels, and precision digital indicators. Designed to prioritize space efficiency, multi-digit readability, and industrial-grade performance, this 6-digit display excels at showing complex industrial metrics: equipment operation counts (e.g., "000120" for 120 cycles), precision temperatures (e.g., "0018.5°C"), or process values (e.g., "0220.0V" for voltage).

Its 5.5mm (0.22-inch) digit height balances readability (clear from 0.3–1 meter, typical for industrial control panel viewing) and miniaturization, while the ultra-slim 31×9×5mm dimensions fit into dense industrial PCB layouts—critical for control panels with multiple displays (e.g., temp + pressure + count). The super bright red light (630-635nm) cuts through industrial ambient glare (e.g., factory overhead lights, machine vibrations) without eye strain, ensuring operators can quickly capture critical data.

With common cathode polarity, low power consumption, and RoHS compliance, this display combines durability, cost-effectiveness, and industrial adaptability—ideal for 24/7 operation in high-demand industrial equipment.

Key Features (Industrial Equipment Control Panel-Optimized)

1. Ultra-Compact 6-Digit Design for Industrial Space Constraints

Slim 31×9×5mm Dimensions: Among the smallest 6-digit 7-segment displays, fitting into tight industrial control panel spaces (e.g., compact machine dashboards, portable test equipment). Enables multi-display setups (e.g., 3+ displays for simultaneous metric tracking) without expanding panel size.

5.5mm (0.22-Inch) Digit Height: Balances miniaturization with industrial readability—small enough for dense layouts but large enough to distinguish 6-digit sequences (e.g., "000005" vs. "000050") and decimal points (e.g., "0025.8°C") critical for precision industrial control.

Low Envelopment Cost: Compact design reduces material and assembly costs, aligning with industrial equipment manufacturers' cost-efficiency needs—no unnecessary bulk driving up production expenses.

2. Super Bright Red Visibility for Industrial Environments

Targeted Red Illumination (40-50mcd, 630-635nm): Red light is highly distinguishable in noisy industrial settings, avoiding confusion with machine lights or background colors. It stands out for alert values (e.g., "999999" for max capacity) and remains visible even in dusty or slightly foggy factory conditions.

Continuous Uniform Segments: No "hot spots" or dim edges across segments (laboratory-tested <2% brightness variation)—ensures every digit (0-9) and decimal point is crisp, eliminating misreads of fine values (e.g., "0012.3" vs. "0012.8") that could disrupt industrial processes.

Stable Performance Under Industrial Stress: Withstands temperature fluctuations (-10°C to 60°C, typical for factories) and minor vibrations (e.g., machine operation, panel handling)—maintains consistent brightness, no flickering during value updates (e.g., real-time cycle counts).

3. Energy Efficiency & Industrial Durability

Low Power Consumption (5-10mA/LED): Extremely low current draw minimizes energy use for 24/7-run industrial equipment (e.g., assembly line controllers), reducing operational costs and lowering strain on industrial power systems.

Long Lifetime (50,000+ Hours): High-quality red LED chips match the 8–10 year service life of most industrial equipment—eliminates downtime from frequent display replacements, critical for continuous-production factory environments.

Easy Assembly for Industrial Production: Compatible with PCB direct-mounting and automated SMT (Surface Mount Technology) lines—speeds up high-volume industrial equipment manufacturing and ensures secure, vibration-resistant installation.

4. Versatility & Compliance

Common Cathode Polarity: Works with standard industrial driver ICs (e.g., TM1638, HT1621, MAX7219) widely used in control panels—simplifies circuit design and integrates seamlessly with industrial firmware (e.g., sensor data processing, error code generation).

Multi-Color Industrial Options: Beyond super bright red, available in blue (for status indicators), green (for "normal" operation), pure green, amber, orange, yellow, and white—flexible for functional cues (e.g., green = "machine ready", red = "fault alert").

RoHS Directive-Compliant: Free from lead, mercury, and harmful substances—meets global industrial safety standards, ensuring use in international factories and compliance with export regulations (EU, North America, Asia).

Technical Specifications

Applications

This display is purpose-built for industrial equipment and precision indicators, including:

Industrial Equipment Control Panels: Assembly line cycle counters (e.g., "000500" cycles), machine process monitors (e.g., "0015.0V" voltage), or robotics operation timers (e.g., "018000" seconds).

Instrument Panels: Industrial thermometers (e.g., "0080.5°C"), pressure gauges (e.g., "005.0MPa"), or flow meters (e.g., "0012.3L/min").

Home & Commercial Appliances: Compact smart ovens (e.g., "00180°C" bake temp), high-precision humidifiers (e.g., "0055% RH"), or commercial refrigerators (e.g., "00-18°C" freezer temp).

Digital Indicators: Portable temperature/humidity meters (e.g., "0025.5°C/0060% RH"), battery testers (e.g., "0012.6V"), or weight scales (e.g., "001500g").
