Encoder Products Company (EPC) is a leading designer and world-wide manufacturer of motion sensing devices. EPC began operations in 1969, producing a line of custom encoders (the original Cube series) from a small, home-based shop. Today, EPC is the largest privately-held encoder manufacturer in North America, producing a line of incremental and absolute rotary encoders that includes everything from compact modules, to linear measurement solutions, to programmable encoders.
