Optical sensors are devices which are used for detecting the presence or absence of an object as well as for determining the speed of an object or measuring its distance. Photointerrupters, which are a type of optical sensor, work on the principle of photovoltaic or optical isolation. They are used in many applications and the OPB481L11Z photointerrupter is a particular type of photointerrupter known as a slot type with logic output.

The OPB481L11Z photointerrupter consists of an infrared light source and an array of eight photodiodes mounted in a V-shaped slot. It is a non-contact device that is used to detect the presence or absence of an object in its detection zone. When an object passes through the detection zone, the light emitted from the light source is blocked by the object and this interruption of light is detected by the photodiodes. The photodiodes then send out electrical signals that are processed by the IC to determine the presence or absence of an object. This type of photointerrupter has logic outputs which allow it to be used in applications such as proximity switching, object detection, and motion sensing.

The OPB481L11Z is ideal for applications such as detecting the presence of paper or documents in printers and copy machines. It can also be used to detect whether a disk is in a disk drive or to stop a machine during a jam or an overload. The photointerrupter can also be used for counting the passing of objects or for sensing the speed of objects.

The OPB481L11Z is a highly reliable device as it has a relatively low failure rate in its application due to the optically isolated output which ensures that it is not affected by electrical noise. Furthermore, the low cost of the photointerrupter makes it an attractive choice for applications where cost is a consideration. The low power consumption of the device also makes it an efficient choice for battery operated applications.

The OPB481L11Z photointerrupter is a reliable and cost-effective choice that provides accurate and consistent detection in many applications. This type of photointerrupter is ideal for applications where fast, reliable, and cost-effective detection is required and its optically isolated output enhances its functionality and reliability.
