Immersible ultrasonic transducer BBMU-PHYF-B

high-frequency

Overview
The BBMU-PHYF-B series comprises therapeutic ultrasound transducers designed for medical devices including physical therapy, rehabilitation and medical-aesthetic equipment. Available center frequencies are 600 kHz, 1 MHz and 1.5 MHz. Units operate from -40 °C to +80 °C, are pressure-rated to 10 kgf (1 MPa) and feature IP68 ingress protection. Electrical and acoustic parameters vary by frequency and must be selected as a complete row corresponding to the chosen frequency.

Frequency-specific configurations
Center frequency | Minimum impedance | Capacitance | Peak voltage | Half-power angle at -3 dB | Housing material
600 kHz ±5% | 90 Ω ±20% | 1,600 pF ±20% at 1 kHz | Below 490 Vpp | 8.1° ±10% | Hard aluminum
1 MHz ±5% | 8 Ω ±20% | 3,500 pF ±20% at 1 kHz | Below 300 Vpp | 3.5° ±10% | Hard aluminum
1.5 MHz ±5% | 20 Ω ±20% | 3,000 pF ±20% at 1 kHz | Below 400 Vpp | 2° ±10% | LV12
