CBZG4FD Push-Pull Connector for Portable Ultrasound Systems 2026: 3+9 Mixed-Contact Probe Interface for Ultrasound Diagnostic Units for Russian Client

The CBZG4FD-SMS812-R00E is a CBZG4FD push-pull connector for portable ultrasound systems — a 4F 3+9 mixed-contact connector designed for the probe connection systems of portable ultrasound diagnostic units, integrating power delivery and signal transmission through contacts of varying specifications in one interface. Every specification in this guide is backed by the medical imaging interconnect engineering of Spring Technology.

Pain point: Connecting an ultrasound probe to a portable main unit — where power delivery, control and signal transmission must all reach the probe at once, probes are swapped between examinations, and the device must fit a display, battery, processor and storage in one limited footprint?

Core answer: For a Russian client, Spring Technology supplied the CBZG4FD-SMS812-R00E, a 3+9 mixed-contact CBZG4FD push-pull connector for portable ultrasound systems, designed for the probe connection systems of portable ultrasound diagnostic units. Portable ultrasound systems rely on probes to capture image data from human tissues and organs, transmitting this data to the main unit for processing and display; because the connection between probe and main unit requires simultaneous power delivery, control and signal transmission, the connector must perform multiple electrical functions within a compact space. The 3+9 mixed-contact configuration allows contacts to be assigned by electrical function, so a single connector handles power alongside data or control signals.

This ultrasound probe connector is built on the ZGN.104F hermetic socket platform in the 4F (104F) shell family, a sealed panel-mount design suited to medical imaging equipment.

• Latching Mechanism: Push-pull self-latching system (quick-connect for probe changes)
• Recommended Hardware: Spring Technology Circular Connector
• Key Metric: 3+9 mixed contacts; integrated power and signal; compact probe interface

Probe interfaces pack many electrical functions into very little space. The design highlights below explain why this CBZG4FD push-pull connector for portable ultrasound systems suits diagnostic units:

• 3+9 mixed-contact structure integrates power and signal — while traditional equipment might require multiple interfaces to handle power and signal separately, this design integrates diverse functions into a single connector: three larger contacts for power and nine smaller contacts for data, control or other low-voltage signals, reducing the number of independent interfaces between probe and main unit and simplifying cabling.
• Contacts of varying specifications meet diverse electrical requirements — power lines typically need to carry higher currents whereas data and control signals prioritize stable transmission; the 3+9 arrangement uses contacts of different specifications for each function, offering greater flexibility and a more efficient match with the device’s internal circuitry.
• Single interface reduces connection complexity — ultrasound probes are external devices that require frequent connection and replacement, and relying on multiple separate connectors for power, control and signals would increase device interfaces and complicate probe cabling; the 3+9 hybrid insert consolidates multiple functions into one interface, simplifying the connection architecture.
• Compact solution for portable devices — portable ultrasound systems integrate a display screen, battery, processor, storage module and probe interface within a limited footprint; combining power and signal in one hybrid insert reduces the interface’s space so more room remains for the device’s miniaturized design.
• Facilitates probe installation and replacement — different examinations require different probe types, and the quick-connect design simplifies installation, removal and replacement, reducing equipment maintenance and operating time.
• Sealed construction and gold-plated contacts — the hermetic ZGN socket body supports clinical use, with stable signal paths for imaging data.

The 4F (104F) shell is part of Spring Technology’s waterproof and hermetic connector families, used in medical, broadcast and high-density equipment. The same platform serves this ultrasound probe connector and scales across plug, socket and mixed-contact variants.

• Shells: 4F (104F) shell size with hermetic socket options (this order uses the ZGN.104F platform).
• Plugs and sockets: TGN.104F straight plugs, TYN.104F short plugs, ZLN.104F and ZGN.104F hermetic sockets.
• Contact layouts: mixed-contact inserts combining larger power contacts with smaller signal contacts, including the 3+9 configuration.
• Panel mounting: hermetic sockets for equipment-side panel installation.

• Custom contact allocations and part numbers (such as the CBZG4FD-SMS812-R00E) matched to each system’s power and signal plan.
• Mixed-contact insert design with contacts of different specifications for power and signals.
• Sealing verification for clinical environments.
• Pre-wired probe cable assemblies.

Diagnostic imaging depends on probes that connect reliably and swap quickly. This CBZG4FD push-pull connector for portable ultrasound systems supports both requirements.

The 3+9 mixed-contact insert links each probe to the ultrasound main unit, carrying power to the probe along with data and control signals.

The hermetic socket mounts at the main unit, where a single interface replaces multiple separate connectors for power, control and signals.

Different examinations require different probe types; the quick-connect design shortens probe installation, removal and replacement time.

This 4F mixed-contact connector delivery for the Russian client shows how Spring Technology serves diagnostic imaging equipment — from the 3+9 contact assignment of the CBZG4FD-SMS812-R00E to its compact probe interface, every detail was aligned with the customer’s requirements for integrated power and signal transmission, multi-channel connectivity, a compact interface and rapid probe replacement. Spring Technology also provides professional customization services for both push-pull connectors and cable assemblies, offering tailored solutions to meet your specific technical requirements.
