Optical Sensors - Reflective - Analog Output - OPB706B Application Field and Working Principle

The OPB706B is an analog output reflective optical sensor specifically designed and manufactured to optimize performance in various industrial and consumer applications. The device can work in extreme conditions, such as high temperatures, and features a wide working voltage range. With a narrow hood angle, the OPB706B has excellent background suppression.The OPB706B is a reflective optical sensor that offers an analog output characteristic of displacement sensing. Its main function is to detect and measure displacements or distances on orderly surface such as PCB boards. This sensor uses the receiving optics of a silicon phototransistor and a light-emitting diode (LED). When the switch is triggered, the LED sends out light and the light will be blocked by an object and could not reach the light sensor at the same time. The changes of light intensity at the light sensor can be converted into an analog output for each displacement or distance.The view angle of OPB706B can be adjusted to adjust the sensitivity of the sensor. An example of the OPB706B application could be for a robot arm to detect obstacles or door openings, for example, if a device or hand is blocking the optical beam between the LED and light sensor. The OPB706B provides an analog output signal to another system, and it sends out its signals to the robot arm accordingly. The flexibility of the view angle adjustment helps to customize the sensitivity for a wider circumference.The OPB706B also features an adjustable dark current. In certain applications, such as photoelectric encoders, it can be used to ensure that the dark current is greater than the maximum signal strength expected. This helps to eliminate the possibility of misreading the signal.Besides adjustable view angle, adjustable dark current, and enhanced sensitivity, the OPB706B also offers excellent ambient light immunity up to 5000 Lux and robust sealing. The internal current regulator is also adjustable making it more adaptive to a variety of applications.The OPB706B is a simple yet efficient device. It provides a reliable, cost-effective solution for a wide range of industrial and consumer applications. Its stable, repeatable and accurate measurements, short response time, excellent thermal stability and reliable performance makes it a great choice. Moreover, the OPB706B is easy to install and simple to use as it requires minimal adjustments for the optimum output.
