S18U Barrel Ultrasonic Sensors

Banner Engineering S18U Barrel Ultrasonic Sensors are compact ultrasonic sensors in straight or right-angle housings. These Banner barrel ultrasonic sensors sense over a 30mm to 300mm range and are available in analog or discrete models. The S18U features minimal dead zone and eliminates the dead zone when used in retrosonic mode. The series is ideal for material-handling and packaged-goods applications, such as bottling or liquid-level detection.
