        Theben PIRA-T8-DE | Recessed Motion and Presence Detector PIR | 360° Detection

        The Theben PIRA-T8-DE is a 360° recessed PIR motion and presence detector, designed for automatic lighting control in indoor environments such as offices, hallways, and commercial spaces. With a detection area up to 50m² (Ø 8m at 2.5m height), it offers wide coverage while maintaining a discreet ceiling-mount profile.

        The sensor uses mixed light measurement for precise brightness detection and includes one 230V lighting channel compatible with a wide range of lamps, including LED, halogen, fluorescent, and incandescent. It operates fully automatically and offers adjustable brightness sensitivity (5–1000 lux) and switch-off delay (5 seconds to 15 minutes), with default factory settings of 100 lux and 2 minutes for fast, out-of-the-box use.

        Rated IP21 for dry indoor use, the PIRA-T8-DE fits standard recessed ceiling installations and supports ceiling heights from 2 to 3 metres. With a compact design and reliable performance, it’s a smart, energy-saving upgrade for modern building lighting systems.
