OA-202C provides Threshold Safety and Activation signaling for sliding or swing style automatic doors. Its detection area is precise, easily aimed, and relatively unaffected by environmental changes. A programmable Threshold Safety circuit actually 'learns' and adjusts to immobile objects, such as boxes or magazine racks that might be placed in the detection area. By incorporating SMD (Surface Mount Device) technology, micro-computer based signal processing and industry leading optical systems, OPTEX is able to provide superior reliability and safety in ONE compact package.
The PROSAFE OA-202C will not only activate an automatic door from over 2m (7ft.) away, but also recognizes the presence of a motionless person from up to 0.8m (2.6ft.) away from the door's threshold, even at floor level. "Hold Open Time" is selectable from 2, 60 or 180 seconds. If any motion is detected during the hold open period, the timer will reset and begin again.
Deep and Wide Detection Area - the OA-202C's detection area consists of 29 individual detection zones which represent 2.3 m. width x 3.0 m. depth maximum at a 2.5 m. mounting height (7.5 ft. width x 9.8 ft. depth at a 8.2 ft. mounting height.) The width and depth of the detection area can be easily adjusted to obtain the desired detection area.
