OPB470N11 Application Field and Working Principle

Optical Sensors are devices that detect the physical presence of objects by sensing light. Sensors come in many forms, such as photoElectric, electroOptical,Slot Type and Logic Output. The OPB470N11 is a type of Slot Type Logic Output optical sensor. This particular device is used in applications ranging from automated device activation and controlling lightings, to industrial sensing and assembly line automation.The OPB470N11 photoInterrupter is an optoelectronic component that consists of an infrared LED emitter, an external interference filter and PIN photodiode detector. The sensing slot is designed to be optically isolated when it is exposed to light. This sensing slot will produce a high level output which can be connected to multiple devices for operation. The optical sensor is highly sensitive to the presence of objects, and features adjustable sensitivity for other configurations.The working principle of the OPB470N11 is based on the principle of interruption of light when an object blocks the light passing through its sensing slot. The infrared LED emitter and external interference filter work together to effectively detect the presence of objects. When an object passes through the sensing slot, the infrared LED emitter will detect the optical blockage, triggering an output signal. The device can detect small objects as well as larger objects, and can also detect motion in both directions. The OPB470N11 comes with a logic output interface. This logic output interface is bi-directional, meaning it can be used for both input and output signals. The resulting output signal from the device can be connected to multiple devices, ranging from mechanical actuators, industrial sensors, and motion control systems. The logic output interface also provides the ability to quickly and accurately measure the size of an object, as well as the speed of its motion.The OPB470N11 is a highly reliable, robust and economical optical sensor. It can be used in a wide range of applications, including industrial automation, machine vision, motion control systems, traffic flow monitoring and more. It is also important to note that the device is IP67 rated, meaning it is suitable for outdoor applications.The OPB470N11, as a type of Slot Type Logic Output optical sensor, is a reliable and cost effective device that can be used for many applications. Its logic output interface provides many advantages, including the ability to accurately measure the size and speed of an object. The device is also highly reliable and robust, and suitable for outdoor applications.
