Optical sensors are widely used in various applications because they provide fast response, high accuracy, and no contact. Photointerrupters are a type of optical sensors commonly used to detect or measure objects by itself. Out of the several types of these photointerrupters available, Slot Type Transistor Output photointerrupter OPB871T51TXV is widely used in devices, systems and components with detection applications due to their respective advantages.

Slot Type Transistor Output (SLT) photointerrupters are comprised of an LED emitter and a phototransistor detector, which are sealed into a small package, making them compact and reliable. The OPB871T51TXV photointerrupter works optimally with a voltage of plus or minus 5 Volts and has high temperature and dustproof characteristics. It is suitable for use in devices with high ambient temperatures and a wide range of detection distances.

The OPB871T51TXV photointerrupter is mainly used in various applications for detection. It is an ideal choice for applications such as flow rate measurement, positioning systems, and shift speed measurement. It is also used in automation systems, as it can detect objects that go in and out of an area, such as a conveyor belt. Additionally, it can be used to detect whether two objects are in contact or not, in automation systems and machines. Optical sensors such as OPB871T51TXV are also used for automatic doors and gates, as well as access and security systems.

One of the main advantages of the OPB871T51TXV photointerrupter is its working principle. It uses a two-stage switching system, which consists of a LED and phototransistor. The LED emits a beam of light which is then blocked off by an object or a line. When the beam is obstructed, the phototransistor stops conducting current and the logic is inverted. This logic can then be used to control switches in the system.

The voltage of the OPB871T51TXV photointerrupter is used as an indicator of the amount of current being drawn out of the LED. When the voltage drops, due to the obstruction of the beam, the current is then detected by the system. This helps the system identify whether or not an object or line has blocked the beam. The voltage is then used to send a signal which can be used to control switches or other functions within the system.

The OPB871T51TXV is extremely reliable and has a wide detection range. The LED is bright and powerful, and the phototransistor is highly sensitive, making it suitable for various detection applications in different devices. It provides reliable switching performance and works optimally with a voltage of plus or minus 5 volts. It has high temperature and dustproof characteristics, making it suitable for use in environments with high ambient temperatures. Additionally, it is cost-effective and consumes low power.

In conclusion, the OPB871T51TXV is a Slot Type Transistor Output photointerrupter that is used extensively in detection applications. It is compact, reliable, and works optimally with a voltage of plus or minus 5 volts. It is suitable for use in devices, systems and components with detection, automation, access, and security applications due to its two-stage switching system and excellent features.
