Product description:

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

Features:

1. TO-46 metal housing
2. Thermistor temperature reference included
3. Low-temperature coefficient of sensitivity
4. Ideally suited for ear thermometers, miniature pyrometer

Applications:

1. Non-contact temperature measurements
2. Ear thermometers, Forehead thermometer
3. Home appliance temperature measurements

Specification:

1. Chip: OTP-638D2; Small size, low cost; Easy to integrate; Medical grade
