1. Features & applications
The DAI640 is an ultra‑compact shutterless uncooled infrared thermal imaging module with a 20×20×20 mm cube design and a weight of only 12 g. Featuring a high‑resolution 640×480 12 μm pixel pitch detector, it delivers crisp thermal imagery while maintaining ultra‑low power consumption (<1 W). The module supports multiple configuration options and a wide selection of interchangeable lenses, making it the ideal building block 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: 20×20×20 mm footprint and only 12 g (without lens) enable seamless integration into the most compact devices.
- Ultra‑low power consumption: < 1 W typical, extending battery life in handheld and UAV applications.
- Shutterless technology: Eliminates mechanical shutter for faster startup (<7 s), higher reliability, and silent operation.
- High‑resolution detector: 640×480 resolution with 12 μm pixel pitch provides exceptional image detail and thermal sensitivity (≤40 mK).
- Flexible customization: Optional infrared lenses (12–50 mm), digital video interfaces, and communication ports to suit diverse system requirements.
- 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: Ideal for covert monitoring, perimeter protection and night vision systems requiring high resolution and small size.
- Industrial predictive maintenance: Enables non‑contact temperature monitoring of electrical cabinets, bearings, and rotating equipment with fine detail.
- UAV / drone payloads: Ultra‑light weight and compact dimensions make it perfect for aerial thermal imaging in search & rescue, agriculture, and infrastructure inspection.
- Handheld thermal cameras: Easily integrated into portable diagnostic tools for building inspectors, firefighters, and field service technicians.
- Automotive night vision: Enhances driver assistance systems with reliable thermal perception in a miniaturized form factor.
