The OPB816 is an optical sensor with slot type, transistor output that is designed to detect objects passing through the gap of the sensing area. It uses the physical principle of infrared transmission to detect objects, which makes it very reliable and dependable in critical applications. It has a high sensitivity and a wide detection range, making it ideal for detection in industrial automation, automotive applications, and industrial safety applications.

The design of the OPB816 consists of two main components - an infrared LED and a phototransistor. The LED produces a narrow beam of infrared light, which serves as the optical signal that passes through the gap of the sensors. When an object passes through the gap, the amount of light reaching the phototransistor is reduced or blocked, resulting in a change in voltage and ultimately a change in the transistor output thus allowing the sensor to detect an object passing by. The change in output is promoted by the collector to emitter voltage, or Vce, of the phototransistor.

The design of the OPB816 has a wide range of detection capabilities. It is able to detect objects that are practically invisible to the human eye, which makes it very useful in low-visibility environments. This makes it a great choice for industrial applications, where objects may be difficult or even impossible to detect and must be detected quickly and accurately. Also, the OPB816 can detect objects travelling at high speeds up to 500 cm/s, which makes it a great choice for automotive applications. The wide detection range also allows for detection of objects even in extreme lighting conditions, so it is suitable for outdoor applications.

The OPB816 also comes with a range of features that make it a very popular choice for applications in industrial safety. It has a fast response time of just 0.3 μs, which means it can detect and react to objects quickly and accurately. Also, it is designed to withstand temperatures ranging from -30⁰C to+ 85⁰C, making it suitable for use in both extremely hot and cold environments. Finally, its long operating life of up to 10,000 hours makes it highly dependable.

The OPB816 is a great choice for applications that require reliable and accurate object detection. It is easy to install and maintain, making it a great choice both for industrial and consumer applications. Its high sensitivity, wide detection range, and fast response time make it suitable for a wide range of industries including automotive, industrial automation, and industrial safety.
