Optical Sensors - Photointerrupters - Slot Type - Logic Output

The OPB993N51 is a photointerrupter that combines a receiver and a light emitter in a small single package. It is used for optical sensing in a varied array of applications where the light emitter transmits an invisible infrared light across a gap and is detected by the receiver. The package consists of an infrared emitter and receiver side by side, aimed at each other in a slot package. The device is for slot-type sensing of printed circuit boards and disk drive logic.

Application Fields

The OPB993N51 is used in a variety of different applications, from industrial sensing and communication to sensing in consumer goods. It can be used in optical signaling, data transfer, photo-disruption, bi-state optical switching, and robotics.The OPB993N51 is extensively used in a wide range of applications in industrial and manufacturing environments. In industrial automation, it is used to sense presence or absence of objects, and in robotic applications, for precise measurement of distances between points and absolute position sensing. The device is also used in a variety of optical sensing or switching applications in communication, consumer electronics, and automotive equipment.

Working Principle

The OPB993N51 consists of two semiconductor die: an infrared light-emitting diode (LED) and a photodiode detector. The LED emits a light beam, which, when passing through the gap between the emitter and the detector, is detected by the photodiode. The photointerrupter is triggered when a gap or interruption in the light beam is detected.When the OPB993N51 is triggered, a logic output is generated. The duration of this output is dependent upon the width of the gap or interruption in the transmitted beam. This makes it possible to detect the exact position of objects with varying levels of precision. The output is generated in the form of either a low or high signal.The device is used in applications that require precise knowledge of the distance of an object, such as robotics and automated manufacturing processes. It is also used in applications that require the detection of precise changes in objects, such as monitoring of disk drive signals, communication protocols, and bi-state optical switching.

Conclusion

The OPB993N51 is a device used in applications such as industrial automation, communication and sensing, robotics, and bi-state optical switching. It consists of two semiconductor die, an LED and a photosensor, which generates a logic output when a gap or interruption in a beam of light is detected. The device is used in applications that require precise knowledge of the distance of an object or detection of precise changes in objects. In all, the OPB993N51 is an ideal component for optical sensing applications.
