High-frequency ultrasonic transducer BBDM-200KR1P5M

proximityfor level measurementfor obstacle detection

Overview
The BBDM-200KR1P5M is an air-coupled ultrasonic transducer for short-range distance and presence sensing. Its 200 kHz center frequency, 0.10-1.5 m reference range and 8 g mass make it suitable for compact automation assemblies used in proximity detection, positioning, counting and level measurement. Typical applications include conveyor monitoring, small-part detection and level sensing in narrow vessels.

Beam characteristic
The specified -3 dB half-power angle is 8 degrees ±10%. This narrow field helps isolate a small target region when the transducer axis and the target surface are aligned; beam spread increases with distance and affects target coverage.

Target alignment and mounting
The narrow beam reduces off-axis coverage and unwanted exposure. Assess target size, surface angle and positional tolerance across the equipment motion envelope. Ensure mounting allows repeatable alignment and provides adequate protection for the cable and connector.
