Optical Sensors are devices that detect light or the presence of an object. They use an optical detector such as a photodetector or photodiode to convert light into an electric signal, which is then used to power a circuit or machine. Photointerrupters are a type of optical sensor used to detect the interruption or presence of an object when it blocks the path of light.

The OPB871L51TXV is a slot type photointerrupter with a transistor output. It is a small, surface mount device that is designed for a wide range of applications. It is commonly used in a variety of industrial, automotive, and avionic systems.

The working principle of the OPB871L51TXV is easy to understand. The device consists of an emitter pin that is positioned in the center of the slot and two sensor pins that are located on either side of the emitter. The emitter emits an infrared lightbeam which is detected by the sensors when something interrupts the light’s path. The output of the photointerrupter is a “low” voltage signal that can be used to trigger an event such as a switch activation, machine or process control, or activation of a safety device.

The OPB871L51TXV is designed for a wide range of applications. It can be used in industrial and automotive sensing and control systems, as well as in avionic systems. It is also suited for optical switches, limit switches, proximity sensing, and edge detection in materials handling systems. Other applications include finger-operated actuators, load cell and strain gauges, high-speed counting and sorting machines, and motor speed control.

In summary, the OPB871L51TXV is an optical sensor specifically designed for use in a variety of industrial, automotive, and avionic systems. It is a slot type photointerrupter with a transistor output which operates on the principle of a light beam being interrupted when something interrupts its path. The output of the OPB871L51TXV is a “low” voltage signal, suitable for triggering a variety of events or enabling machine or process control.
