OPB490T11

OPB490T11 is a type of optical sensors that come in the form of a photointerrupter, slot type, and logic output. It has a wide range of applications that make it suitable for a variety of tasks.

The OPB490T11 is an integrated optical sensor that combines an emitter and a receiver in nine separate, light-blocking slots arranged in a three-by-three matrix. It contains an infrared LED emitter and a photodiode receiver mounted one above the other. When an opaque object passes through the slot, the light between the emitter and receiver is blocked, and the output signal changes. The OPB490T11 outputs a digital signal (either high or low) depending on whether an object is blocking the infrared light.

The wide range of application fields for the OPB490T11 includes robotics and automation, medical, consumer products, packaging, elevator detection, and more. Its most common applications include object detection, proximity sensing, alignment of components, and quality assurance. For example, it can be used in motorized movement systems to detect whether an object is in a desired location or not. It can be used to sort products from a conveyor line in a factory or to count the number of products in a given area. It can also be used for quality control of products to ensure that they meet the desired specifications.

The working principle of the OPB490T11 is simple. When the infrared emitter transmits an infrared signal, the photodiode receiver detects the signal if it is not blocked by an object. If the infrared signal is blocked, then the output signal is automatically changed from a high to a low. The output signal can then be used to trigger a response or action depending on the program of the device.

The OPB490T11 is a versatile sensor offering multiple application fields and a simple working principle. Its ability to detect the presence of an opaque object makes it an indispensable tool for a wide range of tasks. It is also highly reliable and can be used in extreme conditions, making it a valuable asset in hostile environments.
