The 1.1 MHz operating frequency targets the dermis layer, where collagen fibers respond to thermal stimulus. The QM 650 quality factor indicates low loss during electrical-to-mechanical energy conversion.

This frequency and QM combination works with standard push-pull driver circuits commonly used in aesthetic equipment. If you're currently using 1 MHz or 1.2 MHz transducers, this unit may be a direct replacement with circuit adjustments.

The 1.1 MHz ultrasonic transducer configuration uses PZT-4 piezoelectric material. We select components that meet our incoming QC criteria, but final performance depends on your integration, including mounting method and driver settings.

Frequency is tested at 25°C ambient temperature. Performance at other temperatures may vary. If your device operates outside -20°C to +80°C, let us know during the design phase.

This transducer series is used in skin-tightening devices across these treatment types:

• Facial skin tightening: Non-invasive procedures for mild to moderate skin laxity

• Collagen induction: Thermal effect at dermis level supports collagen remodeling-the Collagen Stimulation Transducer mechanism relies on controlled heating rather than mechanical disruption

• Non-surgical lifting: Addresses tissue ptosis through bulk heating-the Facial Lifting Transducer approach works best on patients with good skin elasticity remaining

• Neck and décolletage treatment: Smaller 15mm crystal useful for areas with less flat surface

•Body contouring applications may use this frequency, but performance depends on adipose tissue depth and treatment protocol.

• QM 650 for the primary crystal: Higher quality factor means less heat generation at equivalent power output

• Dual-crystal layout: One transducer supports two impedance paths, which is useful for multi-head designs

• Standard ±2% frequency tolerance: Consistent across production batches

• 304 stainless steel housing: Basic corrosion resistance, suitable for standard coupling media

Quality Factor: High QM ultrasonic transducer design prioritizes stability over maximum power density. For high-power continuous operation, additional cooling considerations may apply.

• Available customization: Frequency range 20 kHz-10 MHz, custom crystal dimensions, impedance matching to your driver

• Standard lead time 7 days for samples, 2-3 weeks for production orders

We manufacture these transducers in-house and can modify the following parameters:

• Frequency: 20 kHz to 10 MHz standard range; tighter tolerance possible for custom orders

• Crystal dimensions: Custom diameters if standard sizes don't fit your head design

• Impedance matching: We adjust the transducer impedance to match your driver output. Provide your driver specs and we run simulations before samples

• Connector: JST-XH and Molex standard; other connectors available, custom pinouts on request

• Lead wire: Standard 100mm, other lengths, shielding, and high-temperature rated wires available

• Housing: Thread specs, mounting flanges, integrated temperature sensors possible
