What are the applicable conditions for the M8 connector with IP67 protection rating? How can the protection effect be guaranteed?

Core Specification Parameters of M8 Series Connectors

Parameter Core Criterion

Industrial Standard Unified Specification : The core specifications of Octopusconn M8 series connectors fully comply with industrial standards, and the key electrical and structural parameters have clear gradient matching rules, which can adapt to different industrial low-power signal and small current transmission scenarios.

Key Specification Parameter Details

Mainstream Pin Count

3 pin / 4 pin / 6 pin / 8 pin

Rated Current

1.5A ~ 4A
(Fewer pins = Higher current)

Rated Voltage

DC30V / AC250V

Protection Grade

IP67 (mated state)
IP68 (partial panel type)

Wiring Method

Welding / Crimping / Tool-free Locking

Cable Outer Diameter

3 ~ 6mm

Current Matching Rule: 3 pin (max 4A) > 4 pin > 6 pin > 8 pin (max 1.5A), the rated current decreases with the increase of pin count.

Technical Note: All core parameters of M8 series connectors follow the unified industrial standard, and the current bearing capacity has a clear gradient with the pin count; the optional panel type IP68 grade is suitable for long-term water immersion and high-humidity harsh environments, and the tool-free locking wiring method can greatly improve the on-site installation efficiency.
