The OPB892N55 is a slot-type Transistor Output Photointerrupter, which is part of a family of optical sensors. Specifically, it is part of the Optek family of optical sensor products and is a two channel type.

The device consists of a detector and an emitter which has a sensing window which is 20 mm in length and 2 mm in width along a height of 5 mm. Between the detector and emitter, there is a physical object or "slot" which interrupts the light between the two. This interruption of light causes one channel of the two to output a logic 0 and the other to output a logic 1.

The overall width of the sensor is 21mm, with the height being 7mm, and the distance between the emitter and the detector being 3.5mm. The technology employed by this sensor is Infrared Emission (IRED) and the wavelength of the IRED is 850nm. The voltage required to operate this device is 12V with a maximum DC current of 10mA, while the output Sink current is used for 0.5mA with the signal on voltage of 1.5V.

This particular model of photointerrupter can be used for applications such as positioning, measuring, and detecting objects on a conveyer belt or in robotic machines. As already mentioned, the sensor is able to detect the disruption of light between the emitter and detector and thereby can be used to detect objects in automated applications. It can also be used to monitor the presence of a physical object between two points in a mechanism.

In general, the typical working principle for this photointerrupter is similar to that of other optical sensors. In this case, they are used to detect the presence of an object on its detection window, which acts as a barrier between the emitter and the detector. When there is an object present, the light that was being emitted by the emitter will be blocked and the two channels that detect this will emit a logic 0 at one and a logic 1 at the other.

In addition, this photointerrupter can be used to determine the size or presence of an object within its detection window. This means that it has a variety of uses in industrial machines and processes. As an example, this model can be used in conveyer systems to detect stolen luggage and other objects. It can also be used in automated systems to measure the length of objects or to detect the presence of a physical object in order to ensure a certain process is correctly followed.

In summary, the OPB892N55 is an example of a slot-type transistor output photointerrupter. It features a 20 mm long and 2 mm wide window along with a 3.5 mm distance between the emitter and the detector and is equipped with Infrared 850nm technology. This model can be used in a variety of applications such as object detection, measuring, and positioning in machines and processes, with the device’s working principle relying on the disruption of light between the emitter and detector.
