BEG PD11-KNXs-FLAT-DX-DE detetor de presença KNX, encastrar, 360°, branco

In modern office buildings, precise presence detection is key to energy efficiency and comfort. The BEG PD11-KNXs-FLAT-DX-DE is a flush-mounted KNX presence detector that monitors a room with a 360° detection angle, distinguishing between fine movements (presence) and larger movements (motion). It integrates a light sensor and temperature sensor, enabling constant light control and HVAC control directly via the KNX bus. Configured with ETS software, it offers three channels for lighting, HVAC, and presence, plus scene control and logic functions. The white housing (RAL 9010) blends discreetly into ceilings, and the UV-stabilised polycarbonate ensures durability. With an IP20 rating, it is designed for indoor ceiling installation.

Key specifications

• Three channels: light, HVAC, presence; constant light control, scene control, logic functions
• Flush-mount ceiling installation; cut-out diameter 60 mm
• Protection class IP20; ambient temperature -25 °C to +50 °C
• Housing: UV-stabilised polycarbonate, white (RAL 9010)
• Configuration via ETS software

Why choose it

This detector combines presence and motion detection with integrated sensors to optimise building automation. Its flat design fits seamlessly into suspended ceilings, and the KNX integration allows flexible control of lighting and HVAC based on actual room usage. The wide detection range and precise light measurement enable significant energy savings while maintaining occupant comfort.

Ideal use cases

• Offices and meeting rooms: automatic lighting and climate control based on occupancy
• Corridors and open spaces: motion detection for safety and energy management
• Educational facilities: presence-based control in classrooms
• Healthcare environments: reliable detection for patient rooms and common areas

Good to know

Installation requires a ceiling cut-out of 60 mm diameter. The detector is powered directly from the KNX bus, eliminating the need for additional power supplies. For commissioning, the ETS software is used to set parameters such as lux thresholds, time delays, and channel functions. Ensure the mounting height is around 2.5 m for optimal detection performance.
