CUI Devices IP Rated Ultrasonic Sensors are available with IP67 or IP68 ratings and are perfect for environments with contaminants. The CUI Devices sensors come in compact aluminum cases as small as 10mm x 10mm x 7mm and offer distance ratings from 0.03m to 15m. The sensors also have analog outputs, beam angles from 7° to 80°, and various mounting options (through hole, wire leads, or wire leads with connectors). With voltage ratings ranging from 150VDC to 500VDC and frequencies from 25kHz to 400kHz, these IP-rated ultrasonic transceivers offer precise measurement for detection, distance, and proximity applications.
