Optical Sensors utilizing Photointerrupters are widely used in many industries and applications. A particular type of Photointerrupter, known as a Slot Type, is characterized by having logic output, typically either NO/NC. OPB982L55 is one such optical sensor which falls into this category. This article will discuss the application field and working principle of the OPB982L55.

The OPB982L55 sensor is widely employed in the industrial control systems due to its highly reliable sensing and performance. It is commonly used in industrial systems to detect the presence of objects or obstacles in the objects’ path. The sensor can detect objects that pass through a slot or gap in the system, allowing it to control the speed of a process and provide feedback information to the system. This feedback system can be programmed to accurately sense when an object passes through the slot and send an alarm signal when the desired speed is reached. Additionally, the sensor can be used to detect if the system has reached its maximum speed or if the machine has overheated.

The working principle of the OPB982L55 is based on its design. The slot-type photointerrupter consists of an emitter section, a receiver section, and a slot in between. The emitter section sends out an infrared beam of light which is then received by the receiver section. When an object, such as a paper clip or sheet of paper, passes through the slot, it interrupts the beam, triggering the sensor to change its output signal. The output signal of the OPB982L55 sensor can be set to either an open collector NO (normally open) connection or an NC (normally closed) connection. Depending on the type of output chosen, the signal will either remain open or close when interrupted, providing a range of options for user-controlled applications.

The OPB982L55 sensor is also known for its high-temperature resistance and long life cycle. It can operate at temperatures up to 120 degrees Celsius, with its accuracy unaffected by environmental factors such as dust and dirt. The photointerrupter’s long life cycle in combination with its high degree of accuracy makes it particularly suitable for applications such as unmanned machine operation and material/product testing. An example of the latter includes robotic arms in a factory setting, which rely on the photointerrupter to detect when an object passes through the slot in order to make precise adjustments.

Overall, the OPB982L55 Photointerrupter is a versatile and reliable sensing device used in a wide variety of industrial, automated, and robotic applications. With a wide operating temperature range, high degree of accuracy, and long life cycle, the sensor provides accurate feedback to control systems and operators’ alike. Additionally, its logic output capability allows for user-controlled applications that are highly accurate and reliable.
