Frequently Asked Questions (FAQ)

Q1: What is the difference between IP67 and IP68 ratings?
A: While both provide dust protection, IP68 offers superior water resistance. Our M19 connector with IP68 rating can withstand continuous immersion up to 1.5 meters depth, unlike IP67 which is limited to temporary immersion.

Q2: Can different core configurations be mated together?
A: No, the polarization system prevents mating between different core configurations. This safety feature ensures correct electrical connections and prevents equipment damage.

Q3: What cable types are recommended for high-current applications?
A: We recommend using silicone rubber or cross-linked polyethylene cables with appropriate current ratings. The connector accepts cable diameters from 6mm to 12mm.

Q4: How does the push-pull mechanism perform in high-vibration environments?
A: The patented bayonet locking mechanism with spring-loaded contacts maintains secure connections even under severe vibration conditions, exceeding industry standards for vibration resistance.

Q5: Are custom pin arrangements available?
A: Yes, we offer custom pin configurations and specialized contact arrangements for specific application requirements. Please contact our technical team for customization options.

Q6: What maintenance is required for long-term performance?
A: The connector is designed for maintenance-free operation. However, we recommend visual inspection every 12 months and cleaning of contact surfaces if exposed to corrosive environments.
