SP17 Medical Circular Connector for Portable Ultrasound Equipment

SD13/SP13 Circular Docking Connector Dimensions and Specs

SP17 Medical Circular Connector for Patient Monitoring & Diagnostic Equipment

The SP17 circular connector is engineered for medical equipment that demands stable signal transmission and dependable environmental protection. Its compact design and IP67 waterproof rating support consistent performance in hospitals, mobile medical carts, and portable healthcare devices.

Built with a durable plastic housing, the SP17 offers strong insulation and corrosion resistance while remaining lightweight. The secure threaded locking system helps prevent accidental disconnection, which is critical in patient-care settings where uninterrupted connectivity matters.

Key Selection Considerations for the SP17 Connector

• Pin configuration: Available in 2–9 pin layouts to match signal and low-power transmission needs.
• Environmental protection: IP67 rating supports use in environments exposed to dust, splash, or cleaning agents.
• Termination method: Solder termination provides a secure electrical connection for field assembly or cable harness production.
• Housing durability: PC/PA66 housing material balances mechanical strength with lightweight portability.
• Contact reliability: Brass contacts with gold plating support consistent signal integrity over repeated mating cycles.

Intended Applications and System Fit

The SP17 is suited for medical devices that require a compact, lockable circular interface. Typical uses include patient monitoring systems, infusion pumps, portable ECG and diagnostic devices, ventilators, blood pressure monitors, and portable ultrasound machines.

For ultrasound probes that transmit high-frequency signals, verify that the SP17's pin count and contact design meet your specific signal integrity requirements before integration. Review connector selection guidance for ultrasound scanner probes to confirm compatibility.

Installation and Maintenance Notes

The SP17 supports solder termination, which allows for secure and repeatable connections during cable assembly. Its threaded coupling mechanism provides a positive lock, reducing the risk of loosening from vibration or movement in portable equipment.

Before installation, confirm the cable outer diameter and conductor size against the connector's clamping range to ensure a proper seal and strain relief. Periodic inspection of the O-ring and mating surfaces is recommended to maintain the IP67 rating over time.

Suitable and Unsuitable Use Cases

Suitable: The SP17 is appropriate for indoor medical devices, portable diagnostic tools, and equipment carts where splash resistance and secure locking are required.

Unsuitable: It is not intended for high-current power distribution, repeated high-flex robotic applications, or environments requiring continuous submersion beyond the IP67 rating. For higher pin-count or higher-current needs, consider other series in the KMYD circular connector range.

Information to Include in Your Inquiry

To receive an accurate quotation and mating recommendation, please provide the following details:

• Required pin count and gender (male or female)
• Cable outer diameter and conductor gauge
• Whether you need a panel-mount or cable-mount version
• Operating temperature and environmental exposure conditions
• Any specific housing color or keying requirements
