Optical Sensors, more specifically, Photointerrupters are devices used to digitally record data and identify objects, or people, of interest. They are composed of two components: an Interrupter (often in the form of a darkened slot) and a Source of Light (most often an LED). The OPB872N51TX is a Transistor Output Slot Type Photointerrupter used to detect objects that pass, and interrupt, the beam of light emitted by the Source of Light.The OPB872N51TX is a small, versatile device that is easy to mount and can be used in a variety of applications. It can be used to detect and identify objects for security and safety applications, such as access control systems, elevators, escalators, and other similar automated conveyance systems. It can also be used in robotic applications, where an object passing through the light beam needs to be identified.The OPB872N51TX is comprised of a Lead frame and a sensing element. The lead frame is made of an anti-reflective sapphire substrate, which produces a clean optical response with high sensitivity. The sensing element is a plastic housing that contains two IREDs. The IREDs produce a low power output that is detected by an NPN transistor when an object passes through the light beam.The working principle of the OPB872N51TX is simple. When an object passes through the beam of light, it interrupts the Stream of Light Equivalent (SLE) that is created, and the NPN transistor is activated. This causes the output signal from the OPB872N51TX to switch from low to high, providing the device with an indication that an object has been detected. The OPB872N51TX is a reliable device that provides accurate and consistent results when detecting objects. It is capable of detecting objects at distances up to 10 cm and can operate at temperatures ranging from -25°C to +85°C. It is also energy efficient and consumes only 2.4 watts of power.The OPB872N51TX is an invaluable tool for the automation industry, as it provides a reliable and accurate method of detecting objects. It is a user friendly device that can be quickly and easily mounted, and is capable of responding accurately to objects that pass through its light beam. Additionally, it is a cost-effective solution for many applications, as it is both reliable and energy efficient. In conclusion, the OPB872N51TX is an effective and reliable device that can be used for a wide variety of applications, ranging from security and safety systems to robotics. It is a user-friendly device that is easy to mount, has a wide operating temperature range, and is energy efficient. The device’s detection capabilities and accuracy make it an ideal choice for many applications.
