The OPB831L55 is an optical photointerrupter slot type, with transistor output, made by M.T.M. SENSORICA company, used mainly for sensing applications. It is a small and lightweight detector, with an easy-to-use mounting layout that makes it suitable for many applications such as vending machines, gaming, vending, printing, vending machines, medical equipment, light control, and industrial applications.

This photointerrupter slot type has a compact size and low profile, designed to enable light transmission while avoiding interference from other light sources. Its construction consists of a light-emitting diode (LED), a collector lens, and a photo-detector, all aligned in a slot configuration. The LED emits light in a narrow beam direction, while the collector lens focuses this light onto the photo-detector which simultaneously receives signals that are reflected from the target object. The signal is then further processed and utilized.

The optical photointerrupter slot type has two primary modes of operation: normal and reverse. Normal mode works in a level-triggering way, where the LED light beam will be emitted between the photo-detector and the collector lens, and the receiver only receives the light signals when objects with a height of at least the set limit is passed through. Reverse mode works differently, where the limit point is the switching point between darkness and light. In other words, when the LED beam is blocked, the transistor will be generated and the photo-detector will be triggered.

The working principle of the OPB831L55 optical slot type is based on the principle of sensing light. When light is shown between the LED and the photo-detector, a small electronic signal is passed between the two components, including a control signal. This control signal allows the voltage output to be regulated between three states: high, low and floating. When this voltage reaches the preset high or low threshold, a change is detected by a control circuit, which then triggers the transistor.

OPB831L55 is used in applications that require detection of fast-moving objects, on paper media, such as labels and tickets. The light emission of this optical photointerrupter slot type is particularly suited to this type of application due to its low power consumption and response time. By activating the electronic signal, the voltage output can be regulated to control the speed of the printing operation. It is also regularly used as a detector in vending machines and other industrial settings. Its compact design makes it a perfect choice for such applications.

The OPB831L55 optical photointerrupter slot type offers many advantages for its users. It is small and lightweight, making installation and maintenance much easier and simpler. Its voltage threshold detection technology ensures accuracy and precision, allowing users to set multiple voltage thresholds for detecting different objects and materials. Additionally, the LED light beams used in this type of photointerruptor are highly focused, which results in better accuracy and decreased power consumption.

In summary, the OPB831L55 optical photointerrupter slot type is an extremely efficient and reliable device, used mainly for sensing applications. It is small and lightweight, and its voltage threshold detection technology allows for accurate and precise operation. Its LED beam focus results in low power consumption, making it a perfect choice for many applications such as vending machines, gaming, vending, printing, vending machines, medical equipment, and light control applications.
