Optical Sensors are devices that are used to detect and measure light and other radiations. The type of sensor depends on the application and the amount of light that is to be detected. Photointerrupters are a type of optical sensor which detects light and other incident radiation and is used when a large amount of light is required to be detected. One of types of photointerrupters is the Slot Type Transistor Output (OPB866L51) which is used for applications such as switching, detection, and light source timing.

The OPB866L51 is a optoelectronic component that is made up of an infrared LED and a phototransistor. The LED typically emits light at 940 nanometers, while the phototransistor can detect light of wavelength ranges up to 900 nanometers. The device emits light when the signal is applied to its base pin, which is usually connected to a logic signal or a microcontroller. The light travels through a small aperture, which is the slit in the photointerrupter and when the light falls onto the phototransistor, the phototransistor is turned on and the output of the OPB866L51 will change in accordance to the voltage of the LED.

The OPB866L51 is usually used in applications where it is necessary to detect and count the number of objects passing by. The photointerrupter works by using optical sensing technology to detect the passing object. When the object passes in front of the photointerrupter, its lens opening is blocked, preventing the light from reaching the internal phototransistor. The output of the OPB866L51 will then change depending on the voltage of the LED. This in turn will help to count the number of objects that have passed by and activate the appropriate action.

The OPB866L51 is also used in applications that require positional sensing. This is due to its stable operation over temperature ranges and wide range of operating angles. The device is able to accurately detect objects at multiple angles, making it suitable for applications where a higher degree of accuracy is required. The wide range of operating temperatures also makes it ideal for outdoor applications, as temperature fluctuations can easily be accommodated.

The OPB866L51 is also used in applications that require switching between light and dark periods and when controlling lighting and other devices in a room. The LED is used to provide illumination and the phototransistor will detect light levels in order to switch between light and dark periods. The device can also be used to detect the presence of objects in the room and adjust lighting accordingly. The OPB866L51 is also used in other applications where sensing and switching needs to be performed.

The OPB866L51 is a small, robust optoelectronic sensor, which is used in a variety of applications in automation, detection and light source timing. It is also used in positional sensing applications, and is able to withstand the fluctuating temperatures of outdoor environments. With its stable operation over temperature ranges, and wide range of operating angles, the OPB866L51 provides an accurate and reliable manner of detecting objects.
