ABOUT YOU, THE CUSTOMER

CONTREX customers are typically, but not always, small to medium sized original equipment manufacturers (OEMs), and system integrators.  Engineers at these firms have the challenge of successfully integrating precision speed and motion control into their designs while focusing on their core product features.

CONTREX precision speed and motion controls require no programming, and come ready for popular end-use applications.  By choosing CONTREX controls, engineers can focus on designing their machines without the hassles, long-lead times, and costs associated with developing a control system from the ground up.

Many other CONTREX customers are manufacturers that need to upgrade or retro-fit an existing machine.  With the help of CONTREX precision speed and motion controls manufacturers can add precision, flexibility, and improve the operator interface of their machines without the down-time and cost of a complete over-haul.  Most importantly, there's no code to write on a CONTREX control, application solutions are achieved by simple parameter code entries or menu selections. Once installed, applications can be commissioned in a matter of minutes.
