THERMOPILE Thermopile Sensor OTP-538U Revision Date: 2009/09/09 OTP-538U Introduction The OTP-538U 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 diameter of 545 μm and with blacken surface to absorb the incident thermal infrared radiation, which induces a voltage response at output terminals.

The sensor chip is fabricated by a unique front-surface bulk micromachining technology, wh
