Thermopile infrared sensor TPiL 8T 2566

passive

Product overview
The Excelitas CoolEYE™ IR Array family includes the TPiL 8T 2566, a 1×8 focal‑plane thermopile line array providing calibrated per‑pixel temperature output via a digital I2C interface. The module integrates onboard sensor temperature measurement and is available with multiple lens options and a metal package for thermal stability and EMI shielding.

Key features

• Calibrated 1×8 focal‑plane thermopile array (8 pixels)
• Digital I2C interface delivering calibrated temperature per pixel
• On‑sensor temperature measurement and per‑pixel temperature calculation
• Selectable lenses for narrow field of view per pixel (L2.5, L3.9, L5.5)
• Metal package for enhanced temperature stability and electromagnetic shielding
• Operating voltage: 3.3 V (optional 1.8 V)
