What does the protection level IP67/IP68 of the M5 connector mean? What are the differences?

IP67/IP68 Protection Rating: Meaning & Differences for M5 Connectors

IP Rating Core Definition

Ingress Protection (IP) Rating : The IP code classifies the degree of protection against solid foreign objects (dust) and liquids provided by electrical enclosures. For M5 connectors, the first digit "6" signifies complete dust protection, while the second digit defines the water resistance level.

IP67 vs. IP68: Detailed Comparison

IP67 Protection Level

Dust Protection : Complete protection against dust ingress.
Water Protection : Protected against immersion in water up to 1 meter deep for a maximum of 30 minutes.
Application : Ideal for general industrial environments, outdoor equipment, and areas with occasional water splashing or temporary submersion.

IP68 Protection Level

Dust Protection : Complete protection against dust ingress.
Water Protection : Protected against continuous immersion in water deeper than 1 meter for an indefinite period.
Application : Suitable for underwater equipment, long-term submerged installations, and harsh, permanently humid industrial environments.

Octopusconn M5 Series IP68 Advantage

The Octopusconn M5 series IP68-rated models feature a dual sealing ring design , which significantly enhances waterproof performance compared to standard single-seal IP67 connectors. This robust construction ensures reliable sealing and long-term stability, even under the most demanding submerged conditions.

Technical Note: Always ensure the connector is fully mated and the sealing ring is properly seated to maintain the rated IP protection. For applications requiring frequent connection/disconnection, inspect the seals regularly for wear or damage. Choose IP67 for temporary water exposure and IP68 for permanent immersion.
