Semtech Proximity Sensors
Proximity sensors are devices that detect objects that are near or moving in their vicinity without actually making contact with them. They use some form of energy to detect objects and can use technologies such as ultrasound, radio frequency (RF), infrared, visible light, and other electromagnetic fields. Proximity sensors are widely used in industrial applications, such as in robotics, point-of-sale systems, machine automation, and other automated systems. They can help machines detect objects that may be difficult to see with the human eye, such as an object in a dark environment or a fast-moving object. Proximity sensors can also make machines much safer by detecting objects in their environment and preventing machines from damaging them.
