      The OTP-628D2 is a thermopile sensor in classic TO-46 housing.

      The sensor is composed of 116 elements of thermocouple in series on a floating micro-membrane having an active area of diameter 545 μm.

      The thermopile sensor provides nearly Johnson-noise-limited performance, which can becalculated by its ohmic series resistance.

      A thermistor with a lead connected to ground is alsoprovided inside the TO package for ambient temperature reference.

    • TO-46 metal housing with IR absorber coating inside.
    • Thermistor reference included. 
    • Low temperature coefficient of sensitivity.
    • Ideally suited for ear thermometers, miniature pyrometer.
