Track sensors are devices used to monitor and detect the presence of objects or vehicles on a specific path or track. They work by using various technologies, such as infrared, ultrasonic, or magnetic fields, to sense when something passes by or is in proximity. These sensors are commonly found in applications like railway systems, automated factories, and traffic management. In addition to detecting objects, track sensors can also provide data for safety and efficiency. For example, in railway systems, they help prevent collisions by alerting operators when a train is on the track. In automated factories, they ensure that machinery operates smoothly by monitoring the movement of products along a production line.
