Industrial Connectors

Training Center Classroom

It’s a harsh world out there in the industrial market for connectors. Humidity, temperature, exposure to chemicals, vibration, shock, and more all affect the reliability and efficient operation of connectors in challenging environments.


In this classroom, we offer various tutorials to help you select the connector that meets your specific needs for your industrial and other high-power applications, such as the types of connectors used on autonomous vehicles to a comparison of EV charging connectors. For those industrial applications also requiring reliability and robust connections, we’ve selected articles focusing on HVAC and other harsh environments, as well as tutorials on liquid cooling for industrial connectors and EVs.


Overcoming design challenges comes with the job. Let us help with a bit of on-the-job training.

Where are liquid-cooled industrial connectors used?

What standards apply to heavy-duty and industrial connectors?

A look at the construction and performance of HDCs found in robotics, automation, power, and more.

An overview of a few standards specific to industrial environments, and connector size and power wiring color coding standards.

This FAQ looks at various liquid-cooled cable and connector structures for carrying up to 60 kA.

Electric Vehicles

What plating options are available for high-power connectors?

Where are liquid cooled connectors and connectors for liquid cooling used in EVs?

What types of connectors are used on autonomous vehicles?

What are the different types of EV charging connectors?

This FAQ starts with a brief review of basic plating system concepts, performance of noble metals, passive metals, and alloys, and the potential benefits of dispersions.

We look at connectors' electrical characteristics, primarily frequency capability, for specific automotive applications.

In this article, we’ll discuss several different vehicle-side EV connector types and compare them, as well as why specific connector types are adopted in different geographies.

Liquid cooling systems can be prefabricated, sealed designs with liquid inside, and ready for installation.
