SD13/SP13 Circular Docking Connector
SD13/SP13 1-7 Pin Docking Wire Connector IP68 – Compact Sealed Plug-in Solution
The SD13/SP13 1-7 Pin IP68 Docking Wire Connector is designed for equipment that requires a small-size, fast-mating, and fully sealed wire-to-wire connection. It combines a compact housing with a precise docking structure, making it suitable for portable devices, modular equipment, and systems where frequent connection and disconnection are required.

With support for 1-7 pins, this series offers flexible configuration from simple power transmission to compact multi-signal integration, while maintaining strong waterproof performance for harsh environments.
Designed for Fast Assembly and Modular Equipment
Unlike panel-mounted or fixed-installation connectors, this docking wire connector is focused on system mobility and quick deployment. It is particularly suitable for applications where equipment modules need to be connected, replaced, or serviced on-site.

The design helps engineers achieve:
- Faster system assembly and disassembly
- Flexible module-level wiring connections
- Reduced installation complexity
- Stable performance in portable or field-use equipment
Key Functional Characteristics
IP68 Full Waterproof Protection
Sealed structure effectively blocks water, dust, and environmental interference, ensuring stable operation in outdoor and industrial conditions.
Compact SD13/SP13 Design
Small housing size makes it ideal for equipment with strict space limitations while maintaining mechanical durability.
1-7 Pin Flexible Configuration
- Low pin count for simple power applications
- Medium configuration for power + signal systems
- Higher pin count for compact multi-channel transmission
Docking Wire-to-Wire Structure
Enables quick connection between cable assemblies without fixed installation, improving flexibility in system design.
Stable Mechanical Mating
Precision alignment structure ensures reliable connection even after repeated plugging cycles.

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
SD16 connectors on my patio string lights—through sun, rain, wind, no glitches. The metal thread is durable, no stripped parts. Great quality!AmazonFindsFan 2026-02-02
Used SD16s on our control panels. The threaded lock is tight, and they’ve held up to dust and vibration. No issues in 3 months—highly recommend.FlashFindsShopper 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
