Product Overview
The IP68 Quick-Connect M12 Connector Harness is a rugged, waterproof connectivity solution engineered for harsh outdoor and industrial environments, exclusively by the SUYI brand. It combines the industry-standard M12 connector—known for its compact 12mm diameter—with an IP68 waterproof rating (the highest level of dust and water protection), enabling reliable performance in continuous submersion and high-pressure water jet scenarios. The integrated quick-lock design allows tool-free, one-step connection, significantly reducing installation time for field or factory use. This harness is tailored for devices requiring uncompromised signal/power transmission in wet, dusty, or corrosive conditions, such as outdoor sensors, energy storage systems, and food processing equipment.
Key Features
IP68 Waterproof & Dustproof Protection: Complies with IEC 60529 standards—100% dust tight and capable of 1.5m water depth submersion for 24 hours, plus resistance to 80bar high-pressure water jets.
Tool-Free Quick-Lock Design: The M12 connector features a built-in quick-lock mechanism, enabling secure connections in 3 seconds without additional tools, ideal for field maintenance.
Weather-Resistant Materials: Housing made of PA66+30% glass fiber—resists hydrolysis, UV aging, and industrial chemicals—while HNBR seal rings maintain elasticity from -40°C to 150°C.
Stable Low-Resistance Connection: Contact pins are made of gold-plated brass (plating ≥0.8μm), ensuring contact resistance ≤10mΩ and preventing corrosion-induced signal loss.
Vibration Resistance: The locked M12 connector withstands 10–2000Hz vibration (per IEC 60068-2-6), suitable for automotive, railway, or heavy machinery applications.
Wide Temperature Adaptability: Operates reliably from -40°C to 85°C, covering extreme cold (outdoor winter) and high-heat (industrial workshops) scenarios.
Chemical Corrosion Resistance: Resists salt spray (500-hour salt spray test pass), making it ideal for coastal or marine-related equipment.
Versatile Compatibility: Compatible with all standard M12-coded connectors (A, B, D, S codes), supporting data, power, and signal transmission.

Product Application Scenarios
The IP68 Quick-Connect M12 Connector Harness excels in moisture, dust, and vibration-prone environments:
Outdoor Energy Storage: Connections for photovoltaic (PV) inverters and energy storage cabinets—resisting rain, snow, and condensation (insulation resistance ≥1000MΩ in 95% humidity).
Food Processing Workshops: Wiring for sensors and control systems in cleaning zones—withstanding high-pressure (80bar) detergent rinsing and chemical corrosion.
Outdoor Monitoring Equipment: Meteorological sensors, hydrological monitoring terminals, and security cameras—operating reliably in -40°C winter or 85°C summer.
Automotive & Transportation: Connections for vehicle sensors (e.g., ABS, radar) and railway auxiliary systems—withstanding vibration and road salt corrosion.
Mining & Wastewater: Wiring for underground mining sensors and wastewater treatment equipment—resisting dust, mud, and corrosive liquids.
Customization Service Process
SUYI’s customization process for the IP68 Quick-Connect M12 Connector Harness focuses on scenario-specific reliability:
Scenario Assessment: Customers share application details (water depth, temperature, vibration level, and signal type) to confirm IP68 suitability.
Engineering Design: Our team selects connector codes (A/B/D/S), cable materials (PVC/PUR), and seal configurations (HNBR/fluororubber for high temperatures).
Prototype Development: A custom M12 connector harness prototype is produced (5–7 working days) with waterproof and vibration testing.
Performance Validation: Prototypes undergo 24-hour IP68 submersion testing, 500-hour salt spray testing, and vibration testing—results provided to customers.
Mass Production: After approval, production starts (10–18 working days); each harness is marked with a unique serial number for traceability.
On-Site Support: For large projects, SUYI provides on-site installation guidance to ensure correct connector locking and waterproof performance.
Quality Assurance & After-Sales Support
72-Hour Factory Testing: Every harness undergoes: 24-hour IP68 submersion test, 100% continuity test, and vibration test (10–2000Hz).
Long-Term Warranty: 24-month warranty on M12 connectors and seal components; 12-month warranty on cables (covering material defects and performance issues).
Emergency Replacement: For critical failures, SUYI provides replacement harnesses within 48 hours (for customers with annual maintenance contracts).
Lifetime Technical Support: Free lifetime software updates (for smart harness variants) and access to SUYI’s technical library of installation guides.
FAQ
What is the maximum water depth the IP68 Quick-Connect M12 Connector Harness can withstand?
It supports continuous submersion at 1.5m depth for 24 hours; custom versions for deeper depths (up to 5m) are available upon request.
Can the harness be used in high-temperature industrial ovens?
Standard versions operate up to 85°C; for high-temperature (≤200°C) scenarios, we offer fluororubber seal rings and silicone cables.
How do I confirm the M12 connector code (A/B/D/S) I need?
Share your application (e.g., data transmission vs. power supply) with our team—we will recommend the correct code (e.g., Code A for power, Code D for Ethernet).
Is the quick-lock mechanism reusable?
Yes—the mechanism supports over 500 mating cycles without compromising waterproof performance.
Does SUYI provide certification documents for the IP68 rating?
Yes—each order includes a test report (per IEC 60529) and compliance certificates (CE, RoHS) for the IP68 Quick-Connect M12 Connector Harness.
