Photoelectric SensorsA photoelectric sensor, or photo eye, is an equipment used to discover the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. | Proximity SensorsA proximity sensor is a transducer that detects objects or signals that are near the sensor element. | Ultrasonic SensorsAn Ultrasonic sensor is a device that can measure the distance to an object by using sound waves. It measures distance by sending out a sound wave at a specific frequency and listening for that sound wave to bounce back |
