The OPB745 Optical Sensor is one of the most popular reflective analog output optical sensors, and it has a wide range of applications. It relies on its unique construction and principles to accurately measure distances or position objects within 3mm to 10mm range.

The OPB745 has a active and passive reflectionless structure which contains multi-beam technology. Initially, a bright infrared LED transmits visible light output. Then, two dichroic mirrors are used to diverge the light from the LED and register it on two receiving photodiodes. The reflected light intensity will be proportionally measured by the two photodiodes. In order to measure a distinct range, an automatic gain control (AGC) circuit is employed.

Since the sensor utilizes energy efficiency, it consumes very little power while serving multiple purposes. It has high noise immunity and interference rejections due to its anti-interference design. Furthermore, its excellent performance is maintained over 1000-hour continuous operation.

The OPB745 can be widely used in multiple fields such as medical engineering, industrial production, intelligent robots, and transportation. Medical engineering often requires precise positioning and accurate range measurement; and the OPB745 can provide accurate information on the position of organs during complicated surgery. In production engineering, it can help to detect defects in products and automatically adjust production process. For example, it can recognize objects, select the right products, and identify malfunctions in the mass production of machinery. Also, it can be used to accurately position and control robots when handling valuable objects in a short period of time.

In transportation, the OPB745 can be used to precisely measure the distances in between objects. Such as a bike lane detector can be designed with OPB745. When the distance between the two flashing lights changes, the OPB745 will detect and measure it. Also, it can be used to detect foreign objects in automated vehicles. Automated vehicles typically align their direction and speed with the help of the OPB745.

In summary, the OPB745 is a very versatile reflective analog output type optical sensor that serves multiple applications. Its efficiency and accuracy is up to the mark and can compete with a variety of optical sensors in the market.
