SD16/SP16 Waterproof Panel Mount Connector
SD16/SP16 2-9 Pin Flange Connector IP68: A Compact Panel Interface for Reliable Systems
The SD16/SP16 2-9 pin IP68 flange connector is a compact, panel-mount interface designed for industrial and outdoor electronic systems. It provides reliable power and signal transmission while ensuring strong mechanical fixation on equipment panels. Its IP68-rated sealing and durable square flange design make it suitable for applications requiring long-term stability and environmental protection.

Designed for Equipment Integration, Not Just Connection
Unlike plug-and-play cable connectors, this flange type is intended to become a fixed interface on equipment housing. It separates internal wiring from external connections, improving system safety and making maintenance and replacement more structured and efficient. This makes it especially suitable for equipment manufacturers who need a standardized, durable, and service-friendly panel interface.

Key Selection Considerations
When choosing the right SD16/SP16 flange connector for your project, evaluate these factors:
-
Pin count: Select 2-9 pins based on your power, signal, or combined requirements.
-
Gender: Confirm whether you need a male or female version for your mating cable or panel side.
-
Mounting: The square flange with four-point fixing suits panel installation where vibration resistance is critical.
-
Environmental rating: The IP68 sealing is intended for continuous immersion or harsh outdoor exposure; verify your actual operating depth and duration.
IP68 High-Level Protection
The sealing structure provides strong resistance against water, dust, and environmental contamination, ensuring stable performance in harsh industrial and outdoor conditions.
2-9 Pins Flexible Configuration
Supports different system requirements:
- Low pin count for power supply
- Medium configuration for power + signal
- Higher pin count for multi-channel control systems
Square Flange Mounting Structure
The four-point fixing design ensures strong mechanical stability, reducing loosening risk caused by vibration or long-term operation.
Stable Electrical Contact Design
The precision contact system ensures consistent conductivity and reliable transmission for continuous industrial use.
Compact Industrial Design
Optimized for space-limited equipment while maintaining structural strength and installation reliability.
