Encoder 101: Selecting the Right Output

In today’s world of high-tech automation, the design engineer must consider a myriad of variables when specifying the right encoder. Incremental vs. absolute output, resolution, and of course physical form factor are key parameters that most every engineer recognizes as top design elements. However, selection of the output chip or “driver” is just as important in many applications. At best, an improperly selected encoder output for the intended application can provide unreliable performance in the form of nuisance-trips, reduced throughput, or diminished production efficiency.
