Introduction

Optical Sensors are transducers which provide signal conversion between an optical input and a corresponding electrical output. These devices detect energy in the form of optical radiation and exist in a variety of forms, depending on their working principles and intended application. One of the most common optical sensor types is the Reflective type, which utilizes the reflection of light to detect the presence or absence of a target object. A variation of this type, the analog output reflective sensor, utilizes reflected light to measure and output analog signal proportional to an input distance. An example of this type of sensor is the OPB706A.

OPB706A Application Field and Working Principle

The OPB706A is a highly sensitive analog output reflective sensor that can measure up to two inches of target distance with an excellent accuracy and repeatability rate. It is ideal for a wide range of applications, such as industrial automation, robotics, medical instrumentation, test and measurement, and other applications requiring remote distance sensing. By integrating an ambient light amplifier and an analog output circuit, the OPB706A is capable of detecting the slight changes in the target distance between the sensing face and the target object surface. The working principle of the OPB706A is based on the reflection of light off of the target object’s surface. The OPB706A sends out a light beam, which is then intercepted and reflected by the target object’s surface. The reflected light is then processed by an internal signal amplifier and evaluated by the internal analog output circuit. Therefore, depending on the target object’s distance from the sensing face, the OPB706A can output an analog signal which is proportional to the input distance. The OPB706A is able to detect very small changes in distance, and is also highly resistant to the negative effects of ambient light.
