      The OTP-638D2 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 be calculated by its ohmic series resistance.
    • TO-46 metal housing.
    • Thermistor temperature reference included.
    • Low temperature coefficient of sensitivity.
    • Ideally suited for ear thermometers, miniature pyrometer.
