1. Features & applications
The DAI640G is an ultra‑compact shutterless uncooled infrared thermal imaging module featuring a 28×28 mm footprint and ultra‑low power consumption (<1 W). Designed for high‑resolution thermal imaging, it offers dual detector options (640×480 17 μm or 640×512 12 μm) with sensitivity down to 30 mK. The module provides extensive configuration flexibility, including multiple lens choices and a wide range of digital video and communication interfaces, making it the ideal solution for cost‑effective OEM assembly and integration in portable, miniaturized, and low‑power thermal imaging systems.
2. Product Features
- Ultra‑small form factor & ultra‑light weight: 28×28 mm PCB size and only 33 g (without lens) enable integration into space‑constrained devices.
- Ultra‑low power consumption: < 1 W typical, extending battery life in portable and UAV applications.
- Shutterless technology: Eliminates mechanical shutter for faster startup (<7 s), higher reliability, and silent operation.
- Dual high‑resolution detector options: Choose between 640×480 17 μm or 640×512 12 μm configurations to balance sensitivity and detail.
- Excellent sensitivity: ≤30 mK (for 12 μm) or ≤50 mK (for 17 μm) @ f/1.0 ensures superior thermal contrast.
- Customizable multiple data interfaces: Wide selection of digital video ports (BT.656/16bit/HDMI/USB/RJ45/MIPI/Cameralink) and communication protocols (RS‑232/RS‑485/TTL/Peclo‑D).
- Advanced image adjustment: Polarity (black/white hot, pseudo color), 1‑8× digital zoom (0.1× steps), brightness control, image flip, and customizable reticles.
- Wide input voltage & protection: Operates from 2.5 V to 5.5 V DC with built‑in reverse polarity and under/over voltage protection.
- Rugged environmental performance: Operating temperature range from -40°C to +60°C (special) and meets GJB 150 vibration/shock standards.
3. Application Scenarios
- Security & surveillance: High resolution and multiple interface options make it ideal for fixed and mobile perimeter protection, border monitoring, and night vision systems.
- Industrial predictive maintenance: Superior sensitivity enables early detection of overheating in electrical cabinets, mechanical bearings, and rotating equipment.
- UAV / drone payloads: Lightweight design and flexible video outputs allow seamless integration for aerial thermography in agriculture, infrastructure inspection, and search & rescue.
- Handheld thermal cameras: Compact size and low power consumption suit portable diagnostic tools for building inspectors, firefighters, and field service technicians.
- Automotive night vision: High-resolution detector enhances driver assistance systems with detailed thermal perception in challenging lighting conditions.
