SD20/SP20 Square Flange Connector Design and Installation Guide
SP20/SD20 2-14 Pin Right-Angle Docking Connector for Laboratory Devices
The SP20/SD20 2-14 pin right-angle docking connector is designed for laboratory and precision equipment that require organized cable routing, stable signal transmission, and efficient module connection within limited installation space. Its right-angle structure combined with a docking connection design helps optimize internal equipment layout while improving accessibility for maintenance and system integration.

Why Choose a Right-Angle Docking Design
Laboratory instruments often contain multiple functional modules within restricted internal space. Traditional straight connectors may increase cable bending stress and complicate wiring arrangements. The right-angle docking structure of this series allows cables to route naturally along the equipment surface, improving airflow, reducing cable pressure, and creating a cleaner internal layout.

Pin Configuration Options for Various Laboratory Systems
This series supports 2-14 pin configurations, making it adaptable for different laboratory device requirements:
-
2-4 Pins: Stable power transmission
-
5-8 Pins: Combined power and control signal applications
-
9-14 Pins: Multi-signal communication and precision data transmission
This flexibility allows engineers to simplify interface design while supporting complex instrument functions.

Key Functional Benefits
- Right-angle structure for efficient cable management
- Docking interface for quick module connection and replacement
- Stable electrical transmission for precision equipment
- Compact design suitable for limited installation spaces
- Reliable sealing performance for long-term equipment stability

Just installed these for my garden LED spotlights—so easy to wire up, and the waterproof seal is tight. Rained heavy 2 days later, zero issues. Worth every penny!HomeGoodsGuru 2026-02-02
Used SD16 on my small air compressor’s control line. Thread lock holds super well, no loose connections from vibration. IP68 lives up to the hype!ShoeLover247 2026-02-02
These SD16 connectors are perfect for my outdoor cameras. The waterproof seal keeps rain out, and the 8-core version handles power + video easily. Super quick to install!ShopAndSmile 2026-02-02
Worked like a charm for my landscape lights. The SD16 connectors snap into place and keep moisture out. So much better than old cable nuts!DIYDecorGal 2026-02-02
