Frequently Asked Questions
Q
What does the IP67 rating mean for the M28 Series connector?
IP67 means the M28 connector is fully dust-tight and can withstand water immersion up to 1 meter for 30 minutes. This protection level is achieved when the connector is fully mated, making it reliable for outdoor and industrial applications such as photovoltaic inverter systems.
Q
What pin configurations are available for the M28 Series connector?
The M28 Series is available in 2Pin, 3Pin, 4Pin, 5Pin, and a 2+8 Pin hybrid configuration. Each pin count corresponds to different rated current and voltage specifications, allowing you to select the most suitable variant for your specific application.
Q
What is the maximum current and voltage rating of the M28 Series?
The 2-pin and 3-pin versions support up to 80A at 600V. The 4-pin version handles 60A at 600V, and the 5-pin version handles 40A at 300V. The hybrid 2+8 Pin variant supports 80A + 10A at 600V + 300V, suited for mixed-signal power scenarios.
Q
What type of locking mechanism does the M28 connector use?
The M28 Series uses a bayonet structure for fast, tool-free mating. No screws or soldering are required — the crimping wiring method ensures a secure, consistent connection while significantly reducing installation time and the risk of loose contacts in the field.
Q
What certifications does the M28 Series connector hold?
M28 Series connectors are certified by UL, CE, CQC, TUV, RoHS, and CCC, and carry IP67/IP68 waterproof ratings. HD photos of all certification documents are available upon request. We can also apply for additional certifications to meet specific regional or industry requirements.
Q
Is OEM/ODM customization available for the M28 Series connector?
Yes, full OEM and ODM customization is supported. You can request custom pin arrangements, current ratings, housing colors, cable entry diameters, and more. As the original manufacturer, we maintain direct control over design and production to ensure fast turnaround and consistent quality for every custom order.
