Laser sensors are devices that use laser beams to detect objects and measure distances. They work by emitting a laser light that reflects off an object and returns to the sensor. The time it takes for the light to return is calculated to determine the distance to the object, making laser sensors highly accurate and reliable for various applications. These sensors are commonly used in industries such as manufacturing, robotics, and automotive. They can help with tasks like automated assembly, collision avoidance, and level measurement. Their precision and speed make them essential tools in modern technology and automation systems.
