Product Description
Product Overview
The AK9710ADF01 is a compact, mid-infrared quantum photo diode manufactured by AKM using unique compound semiconductor technology. Designed for room-temperature operation, it offers high sensitivity, rapid response times (up to 100kHz), and high reliability. This sensor features a built-in optical band-pass filter and is specifically optimized for Non-Dispersive Infrared (NDIR) CO2 sensing applications in automotive environments. Its signal-to-noise ratio is three times higher than conventional thermopiles, and it requires no bias voltage.
