The OTP-868D2 L3.0 is a thermopile sensor with optical lens.

The sensor is composed of 116 elements of thermocouple in series on a floating micro-membrane having an active area of 0.9 mm².  

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 ground is also provided inside the TO package for ambient temperature reference.

TO-46 metal housing with optical lens

Small Field of View (FOV); high Distance to Spot ratio (D:S)

Thermistor reference included

Low temperature coefficient of sensitivity

Ideally suited for forehead thermometers
