Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Core Usage: The Kem 5641 7 Segment Display is designed to display numerical data (e.g., time, temperature, measurements) via four seven-segment LED digits. Its compact design and high-contrast white digits ensure clear readability in diverse environments.
  • Compatibility: Equipped with a standard 20-pin connector, it seamlessly integrates with microcontrollers (e.g., Arduino, Raspberry Pi) and electronic systems for easy implementation in custom projects or industrial setups.

Key features

  • 1. Durable Material Technology for Reliable Performance

  • With a sturdy metal/plastic frame and 2mm pixel pitch, you can ensure long-lasting use and crisp visibility in diverse environments. The compact design is ~30% thinner than standard 4-digit displays*, enabling seamless integration into space-constrained applications.

  • 2. Standardized Connectivity for Easy Integration

  • With 20-pin standardized connectors, you can quickly interface with microcontrollers or systems, saving up to 25% setup time compared to non-standard models*. The modular design simplifies upgrades and repairs.

  • 3. High-Clarity 7-Segment Display for Versatile Data Presentation

  • With a 4-digit 7-segment LED structure and 2mm pixel pitch, you can display numerical data, symbols, and alphanumeric characters with ~20% sharper resolution than displays with larger pixel pitches*. Ideal for clocks, meters, and industrial controls.

  • 4. Compact Design for Multi-Scenario Adaptability

  • With a modern, slim profile, you can deploy this display in home appliances, commercial devices, or industrial systems—unlike bulkier alternatives that limit space-sensitive applications*. The white digits ensure excellent readability in bright settings.

  • 5. Compliance with Global Safety and Environmental Standards

  • With REACH, CE, and RoHS certifications, you can meet strict regulatory requirements for consumer and industrial use without additional modifications*. Trusted for EU and global markets.
