AHKF
Exterior brightness sensor/twilight sensor, with active output
Application
The AHKF is a brightness sensor, housing with quick-release-screw, protection class IP65, measures the illuminance. It is used to control luminaires, lighting systems, blinds and awnings. As well as to monitor lighting conditions at workplaces, in greenhouses, warehouses, workplaces, corridors, exteriors, in industrial halls, in residential and business premises. Futhermore it is used for daylight-dependent constant light control, as a brightness or twilight sensor and as a sun protection control to avoid unnecessary room heating.
