7 Segment Triple 0.56" Common Cathode Blue LED LED Display For Instrument Panel
Product Description
Its 14.2mm (0.56-inch) character height ensures readability from 1–3 meters (typical industrial/equipment operation distance), while the 37.6×19×8mm industrial-standard size fits seamlessly into dense instrument panels—no bulky redesigns required. The ultra bright blue light cuts through ambient glare without eye strain, and the common cathode polarity ensures compatibility with mainstream industrial driver ICs.
Key Features (Instrument Panel-Optimized)
1. Ultra Bright Blue Visibility for Critical Metrics
Targeted Wavelength: Blue light offers high visual distinction in industrial environments, standing out against metallic instrument panels and avoiding "washout" from bright ambient light (e.g., factory overhead lights, stage spotlights for audio equipment). Critical for quick recognition of process values to prevent operational errors.
High-Luminous Intensity: Optimized forward voltage delivers ultra bright output, ensuring readability even in direct sunlight or high-glare industrial settings. No squinting or proximity required to read critical data.
Even Luminous Distribution: Segments emit uniform brightness (≤5% variation) — no "hot spots" or dim edges that distort digits (0-9) or symbols (e.g., decimal points for precision "24.5°C"). Ensures consistent data accuracy across all viewing angles.
2. Industrial-Standard Design & Easy Integration
Compact 37.6×19×8mm Dimensions: Industrial-standard size fits into dense PCB layouts of instrument panels (e.g., multi-parameter controllers, audio mixers) without occupying excess space. Enables multi-display setups (e.g., temp + pressure + frequency on a single panel) without expanding device size.
Common Cathode Polarity: Works with standard industrial driver ICs and microcontrollers —simplifies circuit design for instrument manufacturers and integrates seamlessly with panel firmware.
Easy Assembly: PCB direct-mountable design supports automated production lines—speeds up high-volume manufacturing and ensures secure, vibration-resistant installation (critical for industrial equipment with mechanical operation).
3. Energy Efficiency & Stable Industrial Performance
Low Power Consumption: Extremely low current draw minimizes energy use for 24/7-run instrument panels (e.g., factory process controllers) and extends battery life for portable devices (e.g., handheld digital indicators). Aligns with industrial energy-saving standards and reduces operational costs.
Stable Operation in Variable Environments: Withstands temperature fluctuations and minor vibrations—no flickering or segment failure during data updates or voltage fluctuations.
Long Lifetime: High-quality blue LED chips and industrial-grade construction match the 8–10 year service life of most instrument panels—eliminating frequent replacements, reducing maintenance downtime for critical industrial processes.
4. Versatility & Compliance
Multi-Color Industrial Options: Beyond ultra bright blue, available in red (alarm values, e.g., "999" over-limit), green (normal operation cues, e.g., "050" optimal range), white (neutral precision readouts), amber, orange, and yellow—flexible for functional differentiation (e.g., red for "ERROR", green for "RUN") or brand-specific instrument designs.
RoHS/REACH Compliant: Free from lead, mercury, and harmful substances—safe for industrial and consumer use (even in enclosed instrument cabinets) and export to global markets (EU, North America, Asia), meeting strict industrial safety and environmental standards.
Broad Application Scope: Compatible with audio equipment (volume, frequency), instrument panels (process indicators, temp/humidity), home electronics (smart appliances), and digital counters—reducing the need for multiple display types in product lineups.
5. Instrument-Specific Functionality
3-Digit Capacity for Precision Metrics: Supports 000–999 ranges with decimal points—ideal for instrument-specific data. Enables fine-grained monitoring of industrial processes or audio equipment parameters.
Industrial-Grade Reliability: Resists dust, moisture, and minor impacts (common in industrial environments)—maintains performance in harsh conditions without clarity loss or component damage.
