Optical sensors are devices used to measure and detect light. They are often used in a variety of fields, including robotics, automotive, medical, motion control, manufacturing, and consumer products. The OPB831W55 is an optical sensor specifically for the slot type Photointerrupters, which are commonly used in robotic machines, optical card readers, and monitors. This article will discuss the application field of the OPB831W55 and its working principle.

Application Field

The OPB831W55 is designed for use in small and medium-sized applications in industrial automation. It is an ideal solution for applications that require reliable positioning and precise speed measurement. With its small package size and low profile, the OPB831W55 is easy to install and highly accurate for applications where space is limited. This Photointerrupter is especially useful for applications requiring speed control and problem solving with light beams, such as in robotic machines.

The OPB831W55 is also useful in optical card readers, as it provides rapid response and precise positioning. It is also ideal in the monitoring of packaging and color printing lines and in any application requiring high accuracy in the sensing of movement.

Working Principle

The OPB831W55 is a slot type Photointerrupter, meaning light is emitted from one side of the package and detected on the other side. When a part passes through the slotted opening, the Photointerrupter is activated and an electrical output is triggered. The output is typically a transistor, indicating whether the object is present or absent. The transistor output is known for its fast response time and high signal-to-noise ratio.

The OPB831W55 features an enameled wire lead and is specifically designed to reduce crosstalk from external sources. This feature makes it even more reliable for applications that require precise measurement and sensing of movement. Additionally, the device is RoHS compliant and emits no UV radiation, making it ideal for use in applications where safety is a concern.

In conclusion, the OPB831W55 is an ideal photointerrupter sensing solution for small and medium-sized industrial automation applications. It features a compact package size and low profile, making it easy to install and very reliable for applications requiring speed and positioning control. The device is designed with an enameled wire lead and RoHS compliant, so it can be used safely in applications where UV radiation or crosstalk is a concern. The OPB831W55 sensor also has a fast response time and high signal-to-noise ratio.
