Optical sensors detect changes in light intensity and use this information to measure physical quantities, such as position, velocity, and acceleration. Reflective optical sensors use a light source to measure the reflection from an object. The OPB707A is a reflective, analog output sensor that is used to measure the position of an object with relative accuracy.

The Working Principle

The OPB707A consists of an LED/photodiode pair mounted in an epoxy housing. The LED emits light toward the object of interest. The light that is reflected from the surface of the object is detected by the photodiode, which converted the light into an electrical signal. From this signal, the relative position of the object can be determined. The output signal of the sensor is an analog voltage, proportional to the amount of light detected.

The Application Field

The OPB707A is well suited for applications that require accurate position sensing. It is often used in robotics and automation systems, where the position of an object must be precisely tracked and monitored. Another application where the OPB707A shines is material handling and loading/unloading systems, where the exact position of an object must be monitored. Additionally, it can be used for safety applications, such as obstacle detection systems, where the presence of an object must be detected.

Conclusion

The OPB707A is an excellent choice for applications that require precise position sensing. Its analog output makes it an ideal choice for applications that require analog signals as output. Additionally, its low cost and reliability make it a great value for cost conscious applications.
