Providing medical electronics design engineers with a reflective device capable of an enhanced sensing range in space-constrained applications, the OPB733TR reflective object sensor is being deployed in a wide range of medical equipment. The reflective sensor measures just 0.3 × 0.16 in. with a PC board-mounted profile of just 0.114 in. It incorporates a lensed IR LED and phototransistor elements to collimate the light beam for enhanced resolution at a detection range from 0.4 to 1.0 in. The sensors are available in 16 mm tape on 7 in. diameter reels, 500 pieces per reel.
