Frequently Asked Questions (FAQ)

Q1: What is the difference between IP68 and IP69K ratings?
A: IP68 provides protection against continuous submersion (2 meters for 24 hours), while IP69K adds protection against high-pressure, high-temperature steam cleaning procedures.

Q2: Can these connectors be used in explosive environments?
A: While the connectors feature robust construction, specific certifications may be required for explosive environments. Please consult our technical team for application-specific guidance.

Q3: What is the expected mating cycle life?
A: The connectors are rated for a minimum of 500 mating cycles while maintaining all environmental and electrical specifications.

Q4: Are different thread sizes available?
A: Yes, we offer standard metric and unified thread patterns ranging from M8 to M24 sizes to meet various application requirements.

Q5: How is cable strain relief achieved?
A: The connector features a dual-layer strain relief system with compression gland and internal cable grip that distributes mechanical stress away from electrical contacts.

Q6: Can existing cables be retrofitted with these connectors?
A: Yes, the field-installable design allows for easy retrofitting of existing cables without special tools or training.
