Common Cathode Ultra Bright Red 7 Segment LED Display 18 Pin 2 Digit 0.56inch

Common Cathode Ultra Bright Red 0.56-Inch 2-Digit 7-Segment LED Display (18-Pin, Customizable) for Temperature Controllers & Home Appliances

Product Overview
Introducing the Common Cathode Ultra Bright Red 0.56-Inch 2-Digit 7-Segment LED Display—a high-performance, customizable numeric solution engineered for temperature controllers, digital indicators, and home appliance panels. Designed to balance readability, energy efficiency, and easy integration, this 2-digit display excels at showing core metrics that require concise, clear readouts: temperature (e.g., “24°C” for ACs, “-18°C” for freezers), timer values (e.g., “15min” for microwaves), or device status (e.g., “08” for fan speed).
Its 0.56-inch digit height ensures visibility from 1–3 meters (typical kitchen/living room distances), while the 18-pin configuration provides stable, direct PCB connection—critical for reliable operation in temperature-sensitive devices. The white segments on a black surface boost contrast with ultra bright red light (620-625nm), cutting through ambient glare (e.g., kitchen lights, sunlight) and ensuring readability even in bright environments. With common cathode polarity, low power consumption (5-10mA/LED), and RoHS compliance, it combines durability, functionality, and eco-friendliness—ideal for 24/7 use in home and industrial settings.

Key Features (Temperature Controller & Appliance-Optimized)
1. Superior Visibility for Critical Metrics
Ultra Bright Red Illumination (80-100mcd): Red light (620-625nm wavelength) delivers sharp, eye-catching readouts—perfect for temperature controllers, where quick recognition of values (e.g., “30°C” = overheating) prevents errors. It also minimizes eye strain during prolonged viewing (e.g., monitoring an oven’s temperature).
White Segments on Black Surface: High contrast eliminates “washout” from ambient light and ensures every segment (e.g., the middle bar of “5,” the top bar of “9”) is uniformly lit—avoids misreading digits (e.g., confusing “6” with “0”) that could disrupt temperature control or appliance operation.
0.56-Inch Digit Height: Balances readability and space efficiency—large enough to distinguish small temperature increments (e.g., “22°C” vs. “23°C”) but compact enough to fit into slim appliance panels (e.g., mini temperature controllers for refrigerators).
2. Reliable Performance & Heat Management
Fast Heat-Dissipation: Engineered with heat-resistant materials and a low-power design, the display avoids overheating even during continuous operation (e.g., a temperature controller running 24/7 for a greenhouse). This prevents brightness degradation and extends lifespan.
Stable Operation in Variable Environments: Withstands temperature fluctuations (0°C–50°C, typical for homes/industrial spaces) and minor vibrations (e.g., fridge compressor cycles, oven fan movement)—maintains consistent brightness and segment uniformity, no flickering during value updates.
Long Lifespan (50,000+ Hours): High-quality LED chips match the 8–10 year service life of most home appliances and temperature controllers, reducing maintenance costs and the need for frequent replacements.
3. Easy Integration & Customization
18-Pin Configuration: Provides secure, direct PCB mounting—ensures stable electrical connection and avoids loose pins (a common issue in vibration-prone appliances like washing machines). The pin layout is compatible with standard soldering processes for automated production.
Common Cathode Polarity: Works with standard driver ICs (e.g., TM1637, HT1621, MAX7219) widely used in temperature controllers and home appliances—simplifies circuit design for manufacturers and eliminates the need for custom wiring.
Customizable Design: Supports tailored modifications to fit unique appliance needs, including:
Adjusted digit spacing (for compact vs. wide control panels).
Added decimal points (for precise temperature readouts like “25.5°C”).
Modified segment brightness (for low-light environments like bedrooms).
4. Energy Efficiency & Compliance
Extremely Low Current (5-10mA/LED): Minimizes power draw, making it ideal for battery-powered devices (e.g., portable temperature sensors) or energy-efficient appliances (e.g., ENERGY STAR-certified ACs)—extends battery life by 30% and reduces long-term electricity costs.
Low Forward Voltage (1.8-2.2V/LED): Compatible with standard low-voltage power supplies (e.g., 5V USB, 12V DC adapters) used in temperature controllers and appliances—no need for bulky voltage converters.
RoHS Compliant: Free from harmful substances (lead, mercury), meeting international safety standards for consumer and industrial electronics—safe for use in family spaces (e.g., kitchen appliances) and global markets.

Technical Specifications

Applications
This display is tailored for temperature control and home/industrial appliances, including:
Temperature Controllers: Room thermostats (e.g., “22°C”), fridge/freezer thermometers (e.g., “5°C”/“-18°C”), oven temperature panels (e.g., “200°C”).
Home Appliances: Microwave timers (e.g., “02:00”), washing machine cycle indicators (e.g., “05” for spin speed), AC fan speed displays (e.g., “03” for high speed).
Instrument Panels: Industrial pressure gauges (e.g., “08” for 8 PSI), voltage monitors (e.g., “12” for 12V), humidity controllers (e.g., “50” for 50% RH).
Digital Indicators: Portable weighing scales (e.g., “50” for 50g), battery chargers (e.g., “90” for 90% charge), fitness equipment (e.g., “15” for 15 minutes).
