IP67 Protection Definition of M9 Series Connectors & Unmated State Protection

IP67 Protection Core Connotation

  • Conditional Dual Protection: The IP67 protection grade of M9 connectors is only valid in the state of full mating and tight locking of the nut, including two core protection performance of dustproof and immersion-proof.

Protection Performance in Different Mating States

Mated & Locked State (IP67)

Realize complete dustproof (prevent all dust from entering the internal structure) and 1m immersion proof (soak in 1 meter water depth for 30 minutes without water ingress), meeting the protection requirements of industrial field harsh environment.

Unmated State (Optional Protection)

Conventional models have no protection (plug/socket ports are exposed); special dust caps can be optionally equipped, and the protection grade can be upgraded to IP67 dustproof and waterproof after installation.

Technical Note: The IP67 protection of M9 connectors is not a permanent performance, and the locking nut must be fully tightened to compress the sealing ring to take effect; the special dust cap is a cost-effective protection accessory, which is recommended to be installed for the connectors in long-term unmated state on site.
