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.

How to Select the Right Waterproof Connector

Identify the required interface: power, signal, USB, Ethernet, or RF.
Determine the environmental conditions and required IP rating.
Verify mated or unmated sealing requirements.
Check electrical ratings, data rates, and operating temperature.
Select the mounting method and cable termination.
Compare connector specifications and select the suitable ATTEND product series.

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.

Which waterproof connectors are suitable for industrial automation and robotics?

For industrial sensors, actuators, and robotic equipment, consider M Series Circular Connectors for power, signal, or data connections, Waterproof Pogo Pin Connectors for charging or docking, and Waterproof Blade Connectors for rechargeable battery systems. Select by current, pin configuration, mounting, vibration exposure, and the specific IP rating.

Does ATTEND offer IP67 or IP68 waterproof USB Type-C connectors for outdoor IoT devices?

Yes. ATTEND offers Waterproof USB Type-C Connectors with IP67 or IP68 options for protected power and data interfaces in outdoor IoT and industrial equipment. The rating and its applicable mated or unmated conditions vary by design, so verify the selected part's datasheet and enclosure sealing method.

How do engineers choose between M8, M12, and M23 circular connectors?

Compare the required contact count, current and voltage, data protocol, available installation space, and environmental conditions. ATTEND M Series Circular Connectors include compact M8 options, versatile M12 coding configurations for industrial signal/data connections, and larger M23 options for higher-power applications. Do not assume identical IP or electrical ratings across sizes; check each part number.

What waterproof connector options are available for industrial Ethernet applications?

ATTEND offers IP67 Waterproof RJ45 Connectors for protected Ethernet interfaces and selected M Series Circular Connectors suitable for industrial data applications. Confirm the supported data rate, coding, shielding, cable assembly, and sealing conditions before selection.
