Photointerrupters, or optical sensors, are devices comprising a light-emitting diode (LED) and a phototransistor, which are used to detect the interruptions of a beam of light by an object that passes through the light path. Slot type photointerrupters, such as the OPB865N51, are primarily used to detect the presence of materials that pass through the light beam, which is interrupted by the material. The OPB865N51 has a structure that allows a wide range of sensing patterns, including positive pulse, negative pulse, or switching between two states. The OPB865N51 also has a transistor output for feedback, which enables it to interface with other systems.

The OPB865N51 operates with a system of two light emitters and two detectors so that the interruption of either light path or both light paths can be detected. The emission and reception of light occurs in an elliptical configuration, using the infrared light emitted by the LED to detect if something breaks either light paths. The photointerrupter includes a phototransistor with a gain of up to 200, which allows it to detect small objects or even dust. The OPB865N51 has a wide range of operating temperatures, from -55°C to +125°C. It has an optical axis height of 3.5 mm and a sensing distance of 18 mm, making it ideal for a variety of sensing applications.

The OPB865N51 is used in a wide range of applications. It can be used to perform proximity sensing and to detect the presence of objects such as paper, foil, or metal. It is commonly used in automated assembly systems, where it can be used to detect and control the position of a work piece. It is also used in machine tools to measure linear distances and to help evaluate speed and angular velocity. Additionally, it is used in production and inspection systems to check product features such as holes, slots, or angles.

The working principle of the OPB865N51 is based on the transistor effect. The diode emits infrared light which is then detected by the phototransistor. The phototransistor produces a voltage signal that is sent to the output terminal. When something interrupts the light path, the voltage signal is changed, triggering a signal to the output terminal. This signal is then sent to the system and can be used to control an operation or activate a function. The light emitted by the LED is reflected from the object that interrupts the light, providing feedback to the system.

In conclusion, the OPB865N51 photointerrupter is a highly reliable and precise optical sensor, which is used for proximity sensing and detecting the presence of objects in a wide range of applications. It has a wide operating temperature range and can be used to detect small objects or even dust. The working principle of the OPB865N51 is based on the transistor effect, wherein the diode emits infrared light, which is then detected by the phototransistor and sent to the output terminal, triggering or controlling a specific operation or function.
