Schneider Electric MTN630819 is a SpaceLogic KNX ARGUS flush-mounted presence detector with a 360° horizontal detection field and 7 m lateral reach at a 2.5 m mounting height. Five channels are configurable over the KNX bus for lighting, HVAC and scene control with adjustable light sensitivity and switch-on delay. Creep-zone protection widens near-field coverage under the sensor, and the IP20 housing suits ceiling mounting in dry indoor spaces. Typical applications include occupancy-based lighting in offices, corridors, sanitary rooms and meeting spaces within a KNX installation.
