Theben PIRA T8 AP Detetor de movimento de teto por infravermelhos passivos 360°, montagem à superfície, alcance de 8 m, IP54, Branco 1030203

With a 360° detection angle and an 8-metre diameter coverage at 2.5 m mounting height, the Theben PIRA T8 AP delivers reliable, energy-efficient presence detection for indoor and protected outdoor applications. This surface-mounted ceiling sensor uses passive infrared technology to switch lighting loads up to 2300 W incandescent or 1150 VA LED/fluorescent, with adjustable time and brightness settings for tailored automation.

Overview

The PIRA T8 AP is a compact, round motion detector designed for surface mounting on ceilings. It operates on 230 V AC and features a relay output (normally open) for controlling a single lighting channel. The sensor is housed in UV-stabilised polycarbonate in white (RAL 9010), ensuring durability and a clean appearance. Its IP54 rating protects against dust and splashing water, making it suitable for use in bathrooms, corridors, stairwells, and covered outdoor areas.
