Voltage-Output Infrared Thermopile Temperature Sensor, TO-18 Can
The voltage-output infrared thermopile temperature sensor is a TO-18 metal-can IR sensor that measures object temperature without contact, outputting a voltage proportional to the detected infrared radiation.
Product Overview
This thermopile head detects IR energy through an 8–14 µm filter window and converts it to a voltage signal for non-contact temperature measurement. It is a small TO-18 can with an integrated thermistor (RTD) for ambient compensation, a 0.85 × 0.85 mm sensitive area and a 15 ms response time, aimed at ear/forehead thermometers, industrial non-contact sensing and presence detection.
Key Features
- Non-contact IR temperature sensing in a TO-18 can.
- 0.85 × 0.85 mm sensitive area; 8–14 µm filter.
- Responsivity about 125 V/W; NEP about 0.44 nW/Hz^1/2.
- Integrated RTD for ambient compensation (pins 1/3 thermopile, pin 2 RTD, pin 4 ground).
- Operating range -30 to +100 °C; 15 ms time constant.

FAQ
How does it output temperature? The thermopile produces a small voltage from IR radiation; an external signal board converts it to a usable voltage or digital temperature reading.
What is the filter window? The integrated filter passes the 8–14 µm atmospheric IR band typical for human-body and object temperature sensing.
Do I need an amplifier? The raw thermopile signal is small; a calibrated signal/amplifier board is usually required to get a stable voltage output.
