Encoder Products Company

What Encoder Products Company does

Encoder Products Company (EPC), founded in 1969 and headquartered in Sagle, Idaho, designs and manufactures rotary incremental and absolute encoders, linear measurement solutions, and safety-rated motion feedback devices under the Accu-Coder brand. The company operates a vertically integrated 100,000 square foot ISO 9001:2015 certified manufacturing facility in Idaho where all design, machining, and assembly take place. Its technology stack centers on proprietary Opto-ASIC sensing, the original mechanically isolated Cube encoder design, and the Tru-Trac integrated encoder/measuring wheel system for linear displacement. The portfolio spans shaft encoders, thru-bore and hollow bore encoders, programmable encoders (Model 25SP, 58TP), Ethernet and bus-protocol absolute encoders (EtherCAT, EtherNet/IP, PROFINET, SSI, CANopen, IO-Link, BiSS, SAE J1939), stainless steel variants, and SIL2/SIL3 safety encoders offered through a 2025 partnership with TWK-ELEKTRONIK.

EPC generates revenue through one-time hardware sales of standard catalog encoders (millions of configurations), custom engineering services (1,000+ designs delivered), direct replacement encoders cross-referenced to competitor models, and accessories (measuring wheels, programmers, signal conditioning). Pricing is quote-based rather than publicly listed, supported by an industry-leading 3-year warranty, 6-day standard lead times, and next-day expedite options. The go-to-market combines a North American distributor network, direct field sales engineers, inside sales (5:00 AM–4:30 PM PT), and a direct-to-consumer e-commerce platform at encoderoutlet.com, with international reach through EPC Global offices in 12 countries across the Americas, EMEA, and Asia-Pacific. Customer concentration spans packaging, printing, textiles, mobile equipment, material handling, medical, aerospace, food and beverage, and metal fabrication, with named reference customers including Kirk-Rudy, Ground Force Worldwide, Hipsher Tool & Die, and Litehouse Foods. No external funding, M&A, or ownership changes are disclosed; the company remains privately held and bootstrapped under CEO Bob White.

Product overview

Encoder Products Company (EPC) is a manufacturer of motion feedback devices offering rotary incremental and absolute encoders, linear measurement solutions, and safety-rated encoders. The core product portfolio centers on the Accu-Coder brand with two main encoder types: Absolute Encoders (providing unique position for every shaft location in single/multi-turn variants) and Incremental Encoders (pulsing at intervals for rate/direction feedback). Key product lines include: (1) Ethernet Absolute Encoders (A58SE/A58HE with EtherCAT/PROFINET) and Bus Absolute Encoders (A36/A58 series with SSI, CANopen, BiSS, IO-Link) for various communication protocols; (2) Incremental shaft and thru-bore encoders including Size 25 programmable models (25SP, 58TP) and heavy-duty industrial variants; (3) Tru-Trac linear measurement solutions (TR1, TR2, TR3, TRP) integrating encoder, measuring wheel, and spring-loaded torsion arm; (4) Safety Encoders (TBN/TMN/TRN) including CANopen Safety and TWK SIL2/SIL3 rated variants; (5) Direct replacement encoders for competitor products; (6) Accessories including measuring wheels, programmers (PR1/PR2), signal enhancement devices, and cables. EPC also provides custom engineering services with over 1,000 custom designs. The company recently launched LP1 Accu-LaserPro non-contact optical encoder and expanded IO-Link connectivity across absolute encoder lines.
