SP21 Waterproof Circular Connector for Patient Monitors

GOST OHS Circular Connector with Multiple Core Count Options

SP21 Waterproof Connector for Patient Monitors

The SP21 connector is a medical-grade circular connector engineered for patient monitors and other healthcare devices that require stable power and signal delivery. With a 3–12 core configuration, it supports simultaneous power and signal transmission, making it suitable for diagnostic and imaging equipment where connection integrity is critical.

Waterproof and Durable Construction for Clinical Environments

Designed to perform in demanding conditions, the SP21 features an IP68 waterproof and dustproof rating. The PC/PA66 housing and precision-machined metal contacts provide long-term durability, even in humid or wet clinical settings where equipment may be cleaned or sterilized frequently.

Electrical Performance for Reliable Monitoring

The SP21 delivers stable electrical performance with a rated current of 5–30A and voltage range of 400–500V. Low contact resistance (≤5 mΩ) and high insulation resistance (2000 MΩ) help ensure safe, uninterrupted operation for sensitive medical monitoring applications.

Operating Temperature Range and Installation

Engineered to operate from -40°C to +85°C, the SP21 maintains consistent performance across extreme environmental conditions. Solder termination enables quick, secure installation, supporting reliable long-term connections essential for sensitive medical equipment.

Selection Considerations for Medical Device Engineers

• Confirm the required core count (3–12 pins) based on your power and signal channel needs.
• Verify the mating gender (male or female) and cable entry orientation for your device enclosure.
• Check the operating temperature range against your device's environmental specifications.
• Ensure the IP68 rating matches your cleaning and sterilization procedures.

Application Boundaries

The SP21 is well-suited for patient monitors, portable diagnostic tools, and imaging equipment that require waterproof connections. It is not recommended for applications exceeding the rated current or voltage, or for environments outside the -40°C to +85°C operating range without additional thermal management.

Inquiry Checklist for Ordering

When requesting a quote, please provide the following details to ensure correct configuration: core count, gender (male/female), cable outer diameter, required cable length, and any specific housing color or marking requirements. For mating compatibility with existing equipment, include the device model and connector interface drawing.
