External light level sensors

The LC111x series light level sensor is designed for outdoor applications where it is used for the active control of artificial lighting, both to optimize light levels and to achieve maximum energy efficiency. It uses a photo-diode cell to detect light levels in a selection of lux ranges, providing a linear 4-20mA output signal.



● DIP switch selectable ranges

● 24VDC supply

● 4~20mA output
