BEG BRCK LUXOMAT PD2N-KNXs-ST-DE KNX-aanwezigheidsmelder, 360°, 3 kanalen, wit

With a 360° detection angle and a tangential range of up to 78 m², the BEG BRCK LUXOMAT PD2N-KNXs-ST-DE presence detector delivers comprehensive room coverage for intelligent building automation. This KNX-powered ceiling-mounted sensor combines presence detection, constant light control, and HVAC management in a single discreet unit, making it a cornerstone of energy-efficient lighting and climate control.

Overview

The PD2N-KNXs-ST-DE is a surface-mounted presence detector engineered for KNX bus systems. It operates on bus voltage (21–30 V DC) and integrates seamlessly with ETS software for configuration. The device features three independent channels—light, HVAC, and presence—enabling precise control of lighting, heating, ventilation, and air conditioning based on occupancy and ambient light levels. Its passive infrared (PIR) sensor ensures reliable motion detection, while the built-in light sensor (10–2000 lux) supports constant light control to maintain desired illumination while saving energy.

What stands out

• 360° detection angle with presence range of Ø 4 m (12.5 m²) and tangential range of Ø 10 m (78 m²) at 2.5 m mounting height.
• Three independent channels for light, HVAC, and presence—enables sophisticated automation scenarios.
• Constant light control with integrated light sensor (10–2000 lux) for optimal energy efficiency.
• Compact, UV-stabilised polycarbonate housing in white (RAL 9010) blends into any ceiling.
• IP20 rating suitable for indoor use; operating temperature range -25 °C to +50 °C.
• Low power consumption of approximately 0.8 W from the KNX bus.
