SMA RF Connector for 10MHz Ultrasound Scanner Probes

PC Series Circular Connector Types and Specifications

Selecting the Right Connector for 10MHz Ultrasound Scanner Probes

For ultrasound scanners transmitting high-frequency signals at 10MHz, the connector choice directly affects signal integrity and image clarity. The RF series medical-grade connector with an SMA interface is a suitable option, offering the electrical performance and environmental resistance required for diagnostic imaging equipment.

Key Electrical Specifications for High-Frequency Transmission

The RF series connector supports an operating frequency of ≤18GHz, which comfortably covers the 2~15MHz frequency band used by ultrasound scanners. Its standing wave ratio (SWR) of ≤1.2 ensures low signal attenuation, helping to preserve the high-frequency signal quality needed for clear ultrasound images.

Environmental and Sterilization Compatibility

Medical probe connectors must withstand repeated disinfection. The RF series connector is rated for high-temperature sterilization at 121℃, making it suitable for standard probe cleaning and disinfection cycles. This thermal tolerance supports the operational demands of hospital environments.

Electromagnetic Compatibility and Interference Resistance

The connector complies with the IEC 60601-1-2 electromagnetic compatibility standard. This certification indicates the connector is designed to resist interference from other hospital equipment, reducing the risk of signal disruption during diagnostic procedures.

Mechanical Durability and Maintenance

With a plugging life of ≥1000 cycles, the RF series connector is built for frequent probe replacement and maintenance. This mechanical endurance helps minimize downtime and supports the practical workflow of medical staff.

Selection Note: When specifying a connector for your ultrasound probe, verify the exact mating interface, cable type, and mounting style against your device design. The SMA interface is one common standard, but confirm compatibility with your existing probe assembly before finalizing the component choice.
