TT Electronics/Optek Technology Photologic® OPB931W51 is a through-beam optical sensor module designed for precise object detection. Featuring a 0.125" (3.18mm) sensing distance, this component utilizes a modulated infrared emitter and a phototransistor receiver. The NPN open collector buffer output provides a TTL-compatible signal with a fast 70ns response time. Supplied with wire leads for easy integration, the OPB931W51 is suitable for chassis mounting and operates within a voltage supply range of 4.75V to 5.25V and a current draw of 15mA. This sensor is commonly employed in industrial automation, medical equipment, and office automation applications where reliable non-contact sensing is critical. The operating temperature range is -40°C to 70°C.
