The OPTEX OA-FLEX T is the new door sensor standard for use on automatic sliding doors. The OA-FLEX T combines activation and safety functions into one sensor based on the OPTEX full active infrared technology. The sensor also has a unique "BLUEZONE™" lookback function that offers additional safety in the threshold. The OA-FLEX T complies with the latest European regulation EN 16005 and has been tested and approved by the German test organization TÜV. Activation of the "BLUEZONE™" means the OA-FLEX T offers extra safety beyond even the EN 16005 requirements. For special hospital and kitchen applications there is a touchless pushbutton version available: the OA-FLEX AIR T. Features | Combination The OPTEX OA-FLEX T is purely based on the active infrared technique, combining activation and safety into one sensor. By using the unique OPTEX presence detection technique the OA-FLEX T provides maximum safety around the threshold while simultaneously providing a large motion detection area for door activation. BLUEZONE™ Technology The presence detection area in the OA-FLEX T consists of three rows: two rows in front of the door and an additional bluezone row that looks into the threshold. As soon as the doors start to open the BLUEZONE™ activates and adds an additional row of active infrared. All three rows will be active when someone or something is within the threshold area for as long as the presence timer is set. When the area is safe the doors will start to close again. The BLUEZONE™ recognizes the door movement and will automatically shut off. Easy Adjustment Installation time can be minimized using the easily set switches and trimmers, meaning the sensor can be quickly adjusted for many different applications to modify the presence detection area.
