    Precise NTC: Resistance of 100±1% KΩ at 25℃, β value of 3950±1%, more accurate ambient temperature compensation.

    Low Noise and High Detectability: Noise voltage of 45 nV/Hz¹ᐟ², detectability of 1.0×10⁸ cmHz¹ᐟ²/W, strong weak signal detection capability.

    High-Quality Filters: Average transmittance ≥75% for wavelengths from 5.5 to 14μm, 5μm... With a transmittance of <1%, it boasts outstanding anti-interference capabilities.

    The classic TO-46 package offers maximum ease of use.

    The GT511 utilizes the industrial-grade TO-46 package, featuring a compact size, robust structure, and easy integration and soldering:

    The standard 4-pin design is clearly defined: pins 1/3 are the positive and negative terminals of the thermopile, pin 2 is NTC, and pin 4 is GND, simplifying and maximizing circuit design efficiency.

    The package has precise dimensions, compatible with PCB surface mount and manual soldering. Soldering temperature is 330±20℃, and the soldering time is ≤3 seconds per pin, making it mass-production friendly.

    The integrated high-precision NTC and thermopile chip eliminate the need for additional complex compensation circuits, reducing development costs and time.

    Full-scenario coverage, multi-purpose functionality.

    GT511 With its non-contact, fast-response, and high-reliability characteristics, the GT511 thermopile temperature sensor is widely applicable to medical, home, industrial, and security scenarios:
