Introduction

The OPB881N55 is an optical sensor, known as a photointerrupter, slot type, with a transistor output. This type of sensor detects and senses the presence of a break or dimming of light. It utilizes a separate receiver and a transmissive type optical head, allowing for a detection of even weak signals. This product is mainly used in industrial automation, which includes systems such as 3D printers, automated inspection, and pick-and-place equipment. This article will discuss the application fields and working principles of the OPB881N55.

Application Fields

The OPB881N55 can be used in a variety of application fields. In industrial automation, this type of sensor is used to sense the presence of light or an object. It is extensively used in robotic pick-and-place equipment, automated inspection, and 3D printers. It is also used for carousel sorting, line detection, and detecting discrepancies in printed labels or stamping. In addition to industrial automation, it can be used in consumer applications, such as automating the opening of doors, vending machines, and coffee machines.

Working Principle

The OPB881N55 works by conduction. It sends out an infrared beam of light that is reflected off an object or surface. The amount of reflection detected is dependent on the type of surface and its distance from the sensor. When the light beam is interrupted by an object, a signal is sent to the control circuitry and then sent through the integrated transistor output. This signal can be used to detect and trigger the sensors for various applications.

Conclusion

The OPB881N55 is an optical sensor, photointerrupter, slot type, with a transistor output. It is used in a variety of application fields, such as industrial automation, consumer applications, and automotive applications. The working principle of the sensor relies on reflected light to detect the presence of a break or dimming of light, and the signal is sent to the control circuitry and then sent through the integrated transistor output.
