Optical Sensors - Reflective - Analog Output

The OPB743 optical sensor is a highly efficient reflective device designed to detect a wide range of targets within its scan field. This optical sensor is suited for a variety of applications including motion sensing, optical sensing, and position sensing. It utilizes a rugged glass ball mount for an easy implementation.

The OPB743 uses two sensels connected in series to an adjustable sensing element. The sensor has a highly sensitive non-polarized transducer that receives the reflected signals and amplifies them for an analog output. The transducer consists of a light-conducting path made of a transparent, conductive material. When a target is detected, the sensor triggers the sensels to close, creating a path for current to flow and energizing the transducer. The light created is then detected as one or more momentary impulses from which the sensor can calculate distance or velocity of the target.

The scan field of the OPB743 is adjustable for maximum flexibility. Multiple switches on the device can be used to change the angle of the scan field, allowing the sensor to detect objects in any orientation or at any distance. The transducer can detect targets up to 10 cm away in ideal conditions.

The application field of the OPB743 optical sensor is wide and it can be used to detect objects within multiple industrial and nuclear environments. This sensor has also been successfully employed in aerospace, medical, automotive, and home automation.

The working principle of the OPB743 is straightforward. The sensor consists of two sensels that remain open until an object is detected. When a target is detected, the sensels close and trigger the transducer to energize. The transducer amplifies the reflected signal and sends an analog output back to the user, allowing for easy integration into a variety of applications.
