Movement sensor


The motion sensor Ekinex® EK-SN2-TP is used to detect the passage and standing of persons in a semicircular detection area. It is ideally suited for use in corridors, passage areas, toilets, stairwells, lift landings and generally environments with occasional occupancy. The device has dedicated channels for controlling lighting, HVAC equipment and alarms. Movement/presence detection is carried out by PIR (passive infrared) sensors; a sensor also allows the measurement of ambient brightness. The operating mode is semi-automatic or fully automatic. The device has an integrated KNX bus communication module and is designed for mounting in a flush-mounted wall box; it is powered via the KNX bus and does not require an auxiliary power supply. does not require an auxiliary power supply.
