Optical Sensors - Photointerrupters - Slot Type - Transistor Output:

The OPB821S5 is part of the Optical Sensors – Photointerrupters – Slot Type – Transistor Output family of sensors. It is a high performance, small, low cost, high speed, digital transmission light sensing device.

Unlike some other light sensing devices, the OPB821S5 does not require an external power source, and only requires a single control line for operation. This allows for easy integration into most systems, as the cost of adding and maintaining an external power source can be expensive. It also ensures a more direct link between the component and the main system.

The OPB821S5’s high speed allows for an extremely fast response time to any changes in light conditions. This makes it an ideal choice for many applications that require fast responses. It also has a wide viewing angle, meaning it can detect changes in light from multiple different directions.

The OPB821S5 is designed to provide a digital output, meaning that it can detect changes in light between two thresholds. This makes it ideal for applications that require simple digital signal processing. It also has the ability to detect changes in ambient light, making it suitable for applications such as human/machine interfaces.

The OPB821S5 is also designed to be highly robust. Its metal housing and hermetically sealed construction makes it suitable for use in a variety of environments, including extreme temperatures and temperatures changes, and high and low pressure areas. The OPB821S5 is also designed to have a long-life expectancy, meaning it is suitable for use in applications that will be in use for extended periods of time.

All of these features mean the OPB821S5 is ideal for use in a wide variety of applications, including automotive, security systems, industrial automation, medical, and entertainment systems. It is also a great choice for robotics and other automations that require precise control, as it provides a fast, accurate, and reliable response.

The OPB821S5’s working principle is simple. It detects changes in the intensity of light between two thresholds. This information is then used to control the current through its output transistor. When the detected light intensity rises above the predetermined threshold, the transistor closes, connecting the output device to ground. The output device thus receives the necessary power to operation. When the detected light intensity falls below the threshold, the transistor opens, disconnecting the output from ground and thus disabling the output device.

The OPB821S5 is designed for high-speed operation, making it suitable for many applications where a quick response is required. It is also designed to be highly reliable, meaning it can be used in applications that will be used for long periods of time. This makes the OPB821S5 an ideal choice for use in a variety of applications that require accurate light sensing and control.
