Waterproof Connectors

What Are Waterproof Connectors?

Waterproof connectors are designed for power, signal, data, and RF transmission, using sealing structures, housing designs, and locking mechanisms to reduce the risk of water, dust, and other contaminants entering the connection interface. Depending on the product design and test conditions, protection levels may include IP67, IP68, or other IP ratings. Common applications include industrial automation, robotics, automotive systems, outdoor equipment, and embedded devices.

How Do You Choose a Waterproof Connector?

Choosing a waterproof connector starts with the required interface—power, signal, Ethernet, USB, SIM, or RF—then the required IP rating, mounting method, electrical or data performance, operating temperature, mating condition, cable requirements, and enclosure design.

IP67 and IP68 ratings describe defined ingress-protection test conditions, but the applicable rating may depend on whether the connector is mated and which sealing components are used. Always verify the individual product specification before final selection.

Frequently Asked Questions

What types of waterproof connectors does ATTEND offer?

ATTEND offers waterproof options across multiple connector families, including M Series circular connectors, all-plastic circular connectors, USB, USB Type-C, RJ45, pogo pins, SIM card sockets, Mini FAKRA, and sealed I/O interfaces.

What is the difference between IP67 and IP68 connectors?

IP67 and IP68 represent different water-ingress protection conditions. IP68 test conditions are defined by the applicable product specification and should not be treated as one universal immersion depth or duration. Always verify the individual product specification before final selection.

Are waterproof connector ratings valid when unmated?

Not always. Some connector IP ratings apply only when the connector is fully mated or when specified sealing components are installed. The applicable condition should be confirmed in the individual product specification.

How should I choose a waterproof connector?

Start with the required interface, then evaluate the environmental protection level, mounting method, electrical or data requirements, operating temperature, mating condition, cable requirements, and mechanical constraints of the system.
