Overview
The SD13 5‑Pin Waterproof Connector is a circular, threaded, sealed plug‑and‑socket set (male + female) designed for robust, waterproof electrical connections. It’s part of the SD‑series aviation‑style connectors widely used for power and signal wiring in harsh or outdoor environments.
Key characteristics:
Waterproof & dust‑tight — rated IP68 when properly mated and sealed, making it suitable for outdoor, industrial, automotive, and marine use.
Threaded coupling lock — ensures secure, vibration‑resistant connection that won’t loosen easily under movement or environmental stress.
Durable construction and corrosion‑resistant contacts — shell typically made from nylon (PA66 / polyamide), contacts brass (often gold‑plated), with sealing rings for environmental protection.
| Spec / Attribute | Typical Value / Detail |
|---|---|
| Pin configuration | 7 pins / 7‑pole |
| Rated Current (7‑pin) | 5 A |
| Rated Voltage | Up to 380 V AC/DC |
| Cable insert (wire) diameter supported | Ø 4.0 mm – 6.5 mm |
| Shell material | Nylon (PA66 / Polyamide 66) |
| Contact material & sealing | Brass (gold‑plated) contacts, silicone sealing rings / PPS insulator |
Thanks to its waterproof, sealed, and rugged build, SD13 7‑Pin Connector is used in a variety of contexts:
Outdoor electrical systems — solar panels, garden lighting, outdoor sensors or devices where sealing against water/dust is essential.
CCTV, surveillance, security camera wiring — for power + data/signal connections exposed to environment or outdoor mounting.
Automotive wiring & vehicle installations — for trailers, auxiliary lighting, battery/power modules, wiring harnesses that must endure vibration, dust and water exposure.
Industrial, mechanical, or automation equipment — connecting motors, sensors, control units in factories or outdoor machinery — where waterproofing and reliable contact are needed. Marine, marine‑electronics, and water‑exposed equipment — thanks to IP68 rating and corrosion‑resistant contacts.
Very reliable waterproof & dust‑proof sealing (IP68) — ideal for outdoor, industrial or automotive environments.
Compact 7‑pin design — allows multiple power/signal lines through a single connector, saving space and simplifying wiring.
Secure threaded coupling with vibration resistance — ensures stable connection even under movement or shock.
Good current/voltage rating for many applications — 5 A at 380 V AC/DC is sufficient for low-to-medium power uses.
Durable and corrosion‑resistant — nylon shell, gold‑plated contacts, good insulation make it long‑lasting.
Versatile use across many domains — automotive, CCTV, solar, industrial, marine, automation.
Cost-effective compared to heavy-duty metal connectors — good performance with lighter, cheaper material.
Current rating limited to 5 A — not suitable for heavy power loads or high‑current industrial applications.
Proper sealing & correct cable size are critical — to maintain IP68 waterproofing, must use suitable cable (Ø 4–6.5 mm) and ensure correct threaded coupling.
Not ideal for frequent plug/unplug cycles — rated ~500 mating cycles; frequent connect/disconnect might wear contacts/seal over time.
For high‑power or high‑voltage heavy equipment, higher‑spec connectors may be required — use SD13 only for low/medium power or signal/power combinations.
SD13 7‑Pin Waterproof Connector is a robust, IP68‑rated circular aviation‑style plug and socket set designed for secure, sealed electrical connections in outdoor, automotive, industrial and marine environments. Its 7‑pole configuration supports both power and signal transmission, with threaded coupling, durable nylon shell and gold‑plated contacts ensuring reliable performance even under water, dust, vibration or harsh weather. Rated 5 A / 380 V and supporting cable diameters 4–6.5 mm, it’s ideal for CCTV wiring, solar installations, vehicle harnesses, outdoor lighting, automation equipment or any application where a waterproof, vibration‑resistant multi-pin connector is needed.
