OPB871N55

Optoelectronic devices are used in a wide variety of applications, as they provide quick and reliable detection of objects or changes in their environment. The OPB871N55 optical sensor is an example of such. This slot type photointerrupter with a transistor output is highly sensitive and can be used for a variety of applications. In this article, we will provide an overview of the OPB871N55 application field and its working principle.

The OPB871N55 is mainly used for detection of small and large objects in machinery, robotics, medical equipment, automotive and other industries. It is designed for application in harsh environments, due to its robust and highly reliable design. It features an intense red light emitting diode (LED) and a highly sensitive and compact photo-transistor that are integrated in a single package. The LED emits infrared light which is read by the photo-transistor aligned in an opposing direction and separated by an air gap of 4mm. The sensor\'s unique construction and passivated components provide excellent performance and long life.

The device is able to detect and differentiate between different thicknesses of materials, depending on the size of objects in its detection range. It can detect objects as thin as 0.01 mm and objects up to 25 mm in size. It features an open collector transistor output, which is used to supply power to the device and to transmit the output signals of the device.

The working principle of the OPB871N55 is as follows. The LED and the photo-transistor are separated by an air gap of 4mm. When an object enters the gap, the gap is filled by the object and the light emitted by the LED is blocked, thus triggering the output of the photo-transistor, which is then transmitted to the output device. Since the photo-transistor is highly sensitive, the device can detect even small objects or changes in the environment.

The OPB871N55 is designed for use in numerous applications, as it provides quick and reliable detection of objects and changes. It is extremely reliable and robust, and suitable for a wide variety of environments. Its compact design makes it easy to install and integrate into existing systems. Its highly sensitive photo-transistor is able to detect objects up to 25mm, making it suitable for various applications.

In conclusion, the OPB871N55 is a highly sensitive slot type photointerrupter with a transistor output, suitable for various detection applications. It features an intense red LED and a highly sensitive photo-transistor, which provide excellent performance and long life. The device is capable of detecting small and large objects of various thicknesses, and its output is transmitted through an open collector transistor.
