Level measurement ultrasonic transducer BBDM-80KR5M

proximitymeasurementfor obstacle detection

Overview
The BBDM-80KR5M is an air ultrasonic distance transducer with a nominal center frequency of 80 kHz ±5% and a documented reference range of 0.3 to 5 m. The sensor has a half-power beam angle at -3 dB of 11.5° ±10% and is specified for short-range automation tasks where compact size and IP68 protection are required. It weighs 25 g ±5% (with 25 cm cable) and is rated for operation from -40 to +80 °C and pressures up to 0.3 MPa.
