About Us

Inception
Encoder Products Company Inc. (EPC), a leading designer and world-wide manufacturer of motion sensing devices, was founded in 1969, beginning operations with a small line of custom encoders (the original Cube series!). Today, many years later, EPC manufactures the most complete line of incremental and absolute shaft encoders in the industry, meeting the diverse needs of a wide range of global customers. EPC's core philosophy is that each and every customer deserves quality products, superior customer service, and expert support. Adherence to these principles has enabled EPC to achieve its goal of maintaining long lasting customer relationships.

Products
Inventors of the original Cube encoder, EPC has also been responsible for a large number of "firsts" in the encoder industry, including the first use of Opto-ASIC technology and the first use of flex mounting for hollow shaft encoders, to mention just two. These innovations have not only been widely imitated, they have often become industry standards. The Cube Series is just the beginning of EPC's full line of high-precision, rugged, reliable encoders available in all popular formats. The Round Series includes industry standard sizes 15, 20, 25 and 58. The Thru-Bore Series provides a wide variety of through shaft configurations for a broad range of industrial and motor control applications. The Absolute Series provides accurate positioning information even in the event of power loss. In addition, EPC has developed many ingenious, unique custom encoders for a diverse group of corporate customers.

Innovations
EPC:
• Produced the first "Cube" style of shaft encoder - now an industry standard.
• Designed and introduced the first flex mount style coupling for hollow shaft encoders.
• Was the first to offer 6000 lines of quadrature in a standard size 15 housing.
• Is the only encoder company to offer "expedited" service on custom-built shaft encoders.
• Designed and manufactured the first encoders to operate above 100° C temperature.
• Produces the only encoders that offer internal mechanical isolation for extreme environments.
• Always leads the industry in terms of length of product warranty.

Quality System
When selecting an encoder supplier, your top two criteria will most likely be Quality and Reliability. Quality of both products and services has been a top priority, and a strong advantage, for EPC during our entire 30 plus years as an optical shaft encoder manufacturer. To insure that Quality remains a top priority, EPC has invested heavily in a Quality System that has successfully been audited to the requirements of ISO 9001:2008, an internationally recognized standard for comprehensive Quality Systems. This Quality System incorporates procedures for timely preventive and corrective actions so that the quality of your encoder will keep improving. One visible measure of EPC's emphasis on quality is EPC's best-in-the-industry three-year warranty! Another is that EPC's Accu-Coder™ brand has become known throughout the industry for quality and reliability.

Locations
Our Corporate Headquarters and Americas Division are located close to beautiful Sandpoint, Idaho, 63 miles from the Canadian border. A newly built 100,000 sq/ft facility is where we design, enhance, and provide customized encoders for our global customers. This location is ISO 9001:2008 registered. From this location the Americas Division supports and manufactures encoders for our customers in North and South America as well as encoder components and some completed units for other EPC divisions. EPC's European subsidiary (British Encoder Products Company, BECO) provides the same for European markets and Australia as well as absolute encoders for other EPC divisions. Our Asian Division (Zhuhai Precision Encoder Company Ltd. ZPEC) supports and manufactures several encoder models for sale in the Pacific Rim countries.
Our intention is always to provide our customers with the best value possible as an encoder supplier. Providing not only sales offices, but engineering, manufacturing and repair services positioned around the globe is part of that value.

Support
Encoder Products Company enjoys a well-earned reputation for its support of both its products and services. Factory support directly from trained people is available in the U.S. from 8:00 AM Eastern (5:00AM Pacific) to 7:30 PM Eastern (4:30 PM Pacific). In addition, many of EPC's Distribution Partners have fully trained encoder engineers and technicians on staff.
