The Connor-Winfield Corporation has manufactured electronic frequency timing devices for nearly 40 years since its incorporation in May 1963. Within this timeframe, Connor-Winfield has grown to be a leading U.S. manufacturer of quartz crystal-based hybrid circuits, commonly referred to as crystal oscillators.

Connor-Winfield's frequency control products are used in a broad variety of applications, including telecommunications, LAN and WAN products, computers and other microprocessor and electronic equipment. Connor-Winfield specializes in designing custom and semi-custom frequency control products, but also offers a broad line of standard oscillator products, and oscillators that are not crystal-based.
      We design custom and semi-custom frequency control products both at the system and component level. Our broad line of oscillators and quartz crystals permit us to serve our customers at all levels of their product needs. By fostering a close working relationship between our customers' system designers and Connor-Winfield's engineering group, our customers reduce their product design cycle time, conserve valuable engineering resources, and get their products to market quicker than the competition.
      Connor-Winfield has developed a complete state-of-the-art electronic assembly facility offering a high degree of automation with an emphasis on superior quality. The Custom Manufacturing Services Group has been organized to market these capabilities to OEM's specializing in quick turnaround on prototypes and pilot runs, along with the ability to respond efficiently to complex project runs.

Facility Locations and Manufacturing Capacities

Connor-Winfield has grown significantly in the last ten years and currently employs a staff of over 450 engineers, technicians, assembly operators and support personnel. The Corporate facility is located in Aurora, Illinois with four dedicated manufacturing facilities also in Aurora, a crystal division in Shawnee, Oklahoma, and a sales and distribution facility in Ireland (totaling over 250,000 sq. ft.).

Technologies & Capabilities

We are vertically integrated, from the precision cutting of the quartz crystals through all critical manufacturing processes and final testing. Consequently, we are able to control and monitor every step of the fabrication process. While we are large enough to be efficient and cost effective, we have proudly preserved our small company roots and interactive culture to be flexible and to create products that match our customers' individual requirements. All designs are prototyped and rigorously tested to assure conformance to the specifications required for your products performance, saving you valuable test time and dollars. All Connor-Winfield's network timing products are designed where applicable, to meet and exceed Bellcore specification GR-1244-CORE, GR-253-CORE, ITU-T-G812, ITU-T-G813, and ANSI TI-101

ISO Certification

We believe that quality begins well before our product is ever assembled. By maintaining our ISO 9001 Quality System certification, continuous improvement to our processes is a commitment we make to constantly go beyond the expectations of our customers. For us, quality is not just a technique or system, it is an all encompassing and uncompromising philosophy to produce products that not only precisely meet our customers' quality requirements, but also surpass them in every way.
