SD16/SP16 Waterproof Panel Mount Connector
SD16/SP16 Panel Mount Connector: A Fixed IP68-Rated Equipment Interface
The SD16/SP16 Panel Mount Connector is engineered as a permanent interface solution for industrial equipment, creating a stable and organized connection point between internal circuits and external systems. It suits applications where fixed installation, long-term durability, and structured wiring management are priorities.

Unlike cable-side connectors, this panel mount version integrates directly into equipment housings, serving as a standardized port for power and signal access. It is designed for engineers who need a dependable, serviceable connection point on the equipment panel.
Why Choose a Panel Mount Design?
Separating internal wiring from external connections is critical for safety, maintenance, and system clarity. The SD16/SP16 panel mount connector provides a clear, stable, and serviceable interface that helps you:
- Standardize external connection points across different equipment models.
- Improve maintenance efficiency with a defined, accessible interface.
- Reduce internal wiring complexity and potential points of failure.
- Enhance overall system reliability with a secure, fixed connection.
Key Selection Criteria for Your Application
When evaluating this connector for your project, consider these decision points:
-
Pin Configuration: The connector supports 2 to 9 pins, allowing you to match the contact count to your specific power and signal requirements.
-
Mating Compatibility: This panel mount version is designed to mate with the SD16/SP16 cable-side connectors. Confirm the gender (male or female) of both the panel and cable sides for your application.
-
Environmental Protection: With an IP68 rating, the connector is suitable for demanding environments where protection against dust and prolonged water immersion is required.
-
Mechanical Stability: The threaded locking system ensures a secure connection that resists loosening from vibration, a key factor for equipment in continuous operation.
-
Material Selection: The housing is available in PC or Nylon66, and the insulator is made of PPS, offering a balance of strength, insulation, and thermal performance.
Understanding the Construction and Materials
The connector's construction is designed for reliable performance. The housing materials (PC or Nylon66) provide robust mechanical protection, while the PPS insulator ensures stable electrical insulation. The contacts are made of brass plated with silver, which offers good conductivity and corrosion resistance for long-term reliability.

Manufacturing and Quality Assurance
As a manufacturer with over 15 years of experience in waterproof connectors and cable assemblies, we operate a fully integrated production system. This includes mold design, zinc alloy die-casting, CNC precision machining, injection molding, and final assembly. This in-house capability ensures consistent quality control and stable production capacity.

Each SD16/SP16 connector undergoes rigorous testing before shipment, including electrical conductivity, mechanical strength, plugging cycle durability, and dimensional accuracy checks. Our production processes follow ISO9001 quality management standards.

Customization and Integration Support
We offer flexible customization services to meet specific project needs, including pin configuration adjustment, material optimization, and cable integration solutions. Our engineering team supports you from the design stage through to mass production.

Suitable Applications and Boundaries
The SD16/SP16 panel mount connector is well-suited for industrial control systems, automation equipment, power distribution units, communication devices, and outdoor electronic equipment. However, it is not intended for applications requiring high-frequency data transmission or where a quick-disconnect, tool-free coupling is necessary. For those needs, please consult our other connector series.
