Frequently Asked Questions (FAQ)

Q1: How does the solder-free termination work?
A: The spring-cage mechanism uses a simple push-in design where wires are inserted directly into the contact chamber. A built spring clamp securely holds the wire while maintaining constant pressure for reliable conductivity.

Q2: What is the IP68 rating duration?
A: The connector maintains waterproof integrity when submerged under 1.5 meters of water for up to 24 hours, making it suitable for permanent underwater applications.

Q3: Can existing wired connectors be converted to this system?
A: Yes, the connector is backward compatible with standard M20 threaded interfaces. Existing installations can be easily upgraded without system modifications.

Q4: What maintenance is required?
A: The connector requires minimal maintenance. Periodic visual inspection and cleaning of the mating surfaces are recommended in extreme environments.

Q5: Are special tools required for installation?
A: No special tools are needed. A standard screwdriver for the cable gland and a extraction tool for contact removal are included with each connector.

Q6: What wire types are compatible?
A: The termination system works with solid and stranded copper wires from 24-12 AWG. Both shielded and unshielded cables are supported.
