About Us

IEC Corporation’s history spans over 60 years of building slip rings. A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. Some other names used for slip ring are electrical slip ring, slip ring assembly, collector ring, rotary electrical interface, rotary electrical contact.


In 1955, IEC’s founder Joe McQueen designed his first slip ring and began a one-man operation primarily supporting Texas oil well logging companies. In the years since, IEC has amassed thousands of custom slip ring designs and decades of experience supporting customers worldwide. Through exceptional craftsmanship and attention to customer needs, IEC has become a premier manufacturer of slip ring assemblies for a wide variety of industries around the globe. Today each slip ring is manufactured using state of the art CNC machining equipment and hand assembled at our facility in Austin, Texas.


Unlike many slip ring manufacturers, IEC’s sole business is slip ring assemblies. We are committed to providing the highest quality slip ring in the industry by continuously evolving our capabilities, processes, materials and products. We have supplied slip rings that have traveled into space and combed the deepest depths of the oceans. If your application is mission critical, we have the products and services to meet your needs.
