Photoelectric sensors use light to detect objects and measure distance, with applications in manufacturing, transportation, healthcare, and more. Self-contained sensors can be integrated into machines or used for counting and detecting objects. They are also used as safety devices to shut down machines or trigger alarms. Photocells can be designed to operate in different ways, […]
