[AK9730AJF21] AK9730AJF21
IR Sensor for NDIR Gas Sensing
1. General Description
The AK9730AJF21 is a small mid-infrared quantum photo diode made of AlInSb. It can work at room
temperature by AKM unique compound semiconductor technology, which realizes the high sensitivity,
high speed response, and high reliability. This sensor is optimized to NDIR flammable gas sensing
application. 2. Features High Sensitivity
