ABA-20 series is a true absolute encoder systems, with additional sincos signal, thus, no battery is required. The absolute encoder scales with dedicated bar code patterns, offers in both stainless steel and Robax™ scale. Correspond to each bit. Neither the encoder need to memorize nor to search for a reference point, when power recycled. It is especially suitable for linear motor multi-axis moving products, which can still maintain the working condition in the event of an accidental power failure. The encoder allows easy and quick installation thanks to its loose installation tolerances.
