OTP-638D2 IR Non-contact thermopile sensor - OTP contactless Infrared Temperature Sensor Module
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
