Encoder Products Company

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, more than 48 years later, Accu-Coder 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. Whether it’s a feedback solution for a small stepper motor, a rugged shaft encoder with 95 lbs bearing loads, or a precision measuring wheel, EPC has a variety of products to meet your needs. As inventors of the original Cube encoder, Accu-Coder is also responsible for many “firsts” in the encoder industry - the first to use Opto-ASIC technology, the first to use a flexible mount for hollow shaft encoders, and the first to produce an encoder designed to withstand the demands of high-temperature motor applications, to mention just a few. Accu-Coder’s product line today includes a full array of mechanical package styles and electrical formats to address the multiple challenges of today’s varied applications.
Accu-Coder Absolute Shaft Encoders Distributors
Absolute Shaft

Accu-Coder absolute shaft encoders provide position information for a rotating shaft within either a single rotation (single-turn) or over the course of multiple rotations (multi-turn). The encoder provides a unique digital code or bit for each increment of shaft rotation. Multi-turn absolute encoders store turns-counting information for instant retrieval, even after power down. EPC offers both single-turn and multi-turn absolute thru-bore encoders with a variety of housing sizes, bore diameters, signal types and resolutions.

Accu-Coder Absolute Thru-Bore & Motor Mount Encoders Distributors
Absolute Thru-Bore/Motor Mount

Accu-Coder absolute thru-bore & motor mount encoders provide position information for a rotating shaft within either a single rotation (single-turn) or over the course of multiple rotations (multi-turn). The encoder provides a unique digital code or bit for each increment of shaft rotation. Multi-turn absolute encoders store turns-counting information for instant retrieval, even after power down. EPC offers both single-turn and multi-turn absolute thru-bore encoders with a variety of housing sizes, bore diameters, signal types and resolutions.

Accu-Coder Direct Replacement Encoders Distributors
Direct Replacements

When you have a machine down, you do not have time to waste. At EPC, we understand that, so we offer popular configurations as Direct Replacement Encoders ready for Fast Delivery! After decades of successfully cross referencing and retrofitting thousands of domestic and off-shore encoders, we know how to help you find the right replacement. And we can ship it out fast.

Accu-Coder Incremental Shaft Encoders Distributors
Incremental Shaft

Accu-Coder incremental shaft encoders provide position information for a rotating shaft by producing a continuous series of pulses. These pulses correspond to increments of resolution on the code disk. Incremental shaft encoders are the most widely applied industrial encoders in the world, with an extensive range of form factors and output types. EPC offers a broad array of incremental shaft encoders suitable for applications ranging from fine instrument control to rugged, industrial heavy duty feedback.

Accu-Coder Incremental Thru-Bore & Motor Mount Encoders Distributors
Thru-Bore/Motor Mount

Accu-Coder incremental thru-bore & motor mount encoders provide position information for a rotating shaft by producing a continuous series of pulses. These pulses correspond to increments of resolution on the code disk. Incremental thru-bore and hollow-bore encoders are designed to mount directly to a rotating shaft which passes through the encoder. A flexible tether mount keeps the encoder from rotating with the shaft and absorbs shaft run-out or endplay, minimizing loads on the encoder bearings. Motor-mount style encoders feature a machined housing that attaches a hollow-bore encoder to the NEMA frame motor. To meet varied industrial feedback requirements, EPC offers a broad range of incremental thru-bore and motor mount encoders.

Accu-Coder Linear Measurement Encoders Distributors
Linear Measurement

As the term implies, Accu-Coder rotary encoders generally provide feedback for rotary motion. However, with the addition of a measuring wheel, gear, or cable-draw assembly, a rotary encoder can also provide feedback for linear displacement or measurement. EPC offers a line of integrated linear measurement solutions. They’re easy to install and deliver reliable, accurate feedback for applications such as cut-to-length, spooling, length measurement and print registration.

Accu-Coder Encoder Modules Distributors
Modules

Accu-Coder magnetic encoder modules are flexible, cost-effective feedback solutions. They consist of a modular housing containing the encoder’s hall-effect sensor and signal processing circuitry, as well as a separate magnetic target that is affixed to a rotating shaft. Because encoder modules do not use bearings, the unit’s overall cost and size are greatly reduced. And they offer sealing up to IP69K. Compact, versatile and reliable, EPC encoder modules are suitable for a wide range of industrial, commercial and consumer applications.

Accu-Coder Programmable Incremental Encoders Distributors
Programmable Incremental

EPC's programmable Accu-CoderPro™ programmable encoders are specifically designed for the challenges of an industrial environment. Contained within the rugged, industrial housing is an advanced set of electronics that allow the encoders to be programmed to your exact application needs. Choose from 6 different output types, 32 different waveforms, and program any resolution from 1 to 65,536 CPR - that's 262,144 counts using 4x quadrature counting. (Accu-CoderPro™ encoders can also be configured and shipped with specs pre-programmed, no on-site programming needed.) These programming features allow a single encoder to be configured for multiple applications, enabling one encoder to replace many different part numbers, providing cost savings on inventory -- and shortening down-time for replacement. Available in shaft, hollow bore, and thru-bore, these encoders are highly mechanically configurable and offer a range of bore/shaft sizes, different mounts, a variety of connectors, and sealing up to IP67.

Accu-Coder Stainless-Steel Encoders Distributors
Stainless Steel

For operating environments where abundant moisture, corrosive or caustic agents are present, Accu-Coder offers encoders with housings made of 316 stainless steel. With bearings rated for loads up to 80 lbs axial/radial and IP67 sealing, EPC’s stainless steel encoders are suitable for harsh industrial applications.
