Initially founded in 1986, Trilogy Systems employs 38 people and has annual sales of approximately $6 million. Trilogy is the leading North American manufacturer of linear motors -- an advanced motion-control technology that provides the unique benefits of both high speed and high precision not achieved by traditional mechanical transmissions. Trilogy's patented designs and motors currently under development offer lower costs, extremely smooth motion, and high force capabilities.

According to Parker Automation Group President Bob Bond, the acquisition provides Parker with all of the main technologies in linear motion that cover the widest range of applications, from semiconductor to machine tool.

"Acquiring Trilogy Systems solidifies Parker's position in the fast- growing linear motor market and we are very pleased to add their strengths to our portfolio," said Bond. "The strong product line increases our ability to be an automation solutions provider for a broad range of global machine builders. It enhances our technology offering, integrates well with our drives and controls products, and provides supply base synergies with our rotary motors."

Trilogy Systems President and Founder Bruce Beakley said, "Parker and Trilogy have enjoyed a long association and market success by combining Parker drives and controls with Trilogy linear motors through common distributors. I'm confident that this acquisition will result in even greater success, new opportunities and long-term growth."

Parker Automation Group's Electromechanical Automation Division manufactures a complete line of motion control products including controllers, servo and stepper drives and servo motors. Parker Automation also manufactures, sells and markets other products used in applications involving motion control, robotics and automation.

With annual sales of more than $7 billion, Parker Hannifin is the world's leading diversified manufacturer of motion and control technologies and systems, providing precision-engineered solutions for a wide variety of commercial, mobile, industrial and aerospace markets. The company employs more than 48,000 people in 46 countries around the world.
