Encoder Products Company :: Manufacturer of High-Quality Rotary Incremental & Absolute Encoders

Encoder Products Company (EPC) is a leading U.S.-based manufacturer of high-quality rotary incremental and absolute encoders, as well as linear motion feedback devices. Founded in 1969, the company specializes in precision motion sensing technology used across industrial automation, robotics, packaging, material handling, and other motion control applications. EPC designs, manufactures, and assembles its products in a vertically integrated 100,000+ square foot facility in Sagle, Idaho, emphasizing reliability, customization, and rapid support.

EPC’s encoders provide critical feedback on position, speed, direction, and distance for automated systems. While the company does not produce complete robot platforms, its robot-based products (encoders) are essential components in robotics and autonomous systems. They enable precise closed-loop control in servo motors, robotic arms, AGVs (automated guided vehicles), cobots, and mobile robots by delivering accurate real-time data on shaft rotation or linear movement. This feedback is vital for navigation, positioning accuracy, synchronization, and safety in dynamic environments.

Key product lines include:

• Accu-Coder® and Accu-CoderPro®: Robust incremental and programmable encoders (e.g., Model 260 low-profile thru-bore, Model 58TP 58mm programmable) offering resolutions up to 65,536 CPR, multiple output types, and rugged designs for industrial use. Many models feature IP67 sealing and extended temperature ranges.
• Absolute Encoders: Including multi-turn models and new IO-Link enabled versions for smart connectivity and real-time diagnostics.
• Linear Solutions: Tru-Trac™ wheeled encoders and the new LP1 Accu-LaserPro™ non-contact laser encoder for precise linear measurement without physical contact.
• Safety-Rated Encoders: Through a partnership with TWK-ELEKTRONIK, EPC offers SIL2/SIL3 functional safety encoders ideal for collaborative robots, mobile machinery, and high-safety applications.

EPC products are known for durability in harsh environments (from factory floors to extreme conditions), easy installation (flex mounts, anti-backlash systems), and programmability that reduces inventory needs. The company supports custom engineering, fast lead times, cross-referencing, and repair services. With over 50 years of experience, EPC serves global markets through distributors and has additional operations in the UK and India.

Overall, EPC positions itself as a trusted partner for motion feedback, helping robotics and automation engineers achieve higher performance, efficiency, and safety. Their encoders are found in everything from packaging machines to advanced robotic systems, contributing to the backbone of modern industrial automation.
