The Hengstler AD58 series is a high-performance optical absolute encoder line designed for integration into BLDC servo motors. With single-turn resolutions up to 24 bits and multi-turn up to 12 bits, it delivers precise feedback for demanding applications like CNC, precision positioning, and high-resolution printing. Built for durability in harsh environments, the AD58E and AD58S models offer advanced safety features, meeting SIL 3 and SIL 2 standards respectively. The AD58E also includes the ACURO®link secure interface and integrated temperature monitoring for both encoder and motor winding.
