N-C222SEM

The light intensity measurement range is 0 ~ 65,535 lux, 0 ~ 200,000 lux, and so on.
The built-in high-sensitivity photosensitive probe features stable signal transmission, high reliability, high measurement accuracy, and strong anti-interference performance.
The housing adopts an elegant ceiling-mounted design, making it easy to use and install.
It uses a wide-voltage power supply of 10 ~ 30V, making it suitable for laboratories, archives, electronic equipment production lines, and other indoor areas where light intensity monitoring is required.
The N-C222SEM ceiling-mounted light transmitter is a high-precision photosensitive transmitter that uses a cell-type mounting design, with lux as the unit of measurement for the output data.
