New SinCos SRM 64 motor feedback systems feature Hiperface interface, operate in temperatures from -20° to +110°C, and offer enhanced resistance to shock (100/10 g/ms) and vibration (20/10–2000 g/Hz). Hollow shaft bores are available for up to 14 mm shafts. These IP65-rated, multi-turn servo motor feedback systems are well suited for applications requiring high resolution, or the Hiperface interface. The devices, which can be mounted externally to a servo motor, are designed to provide precise absolute positioning with 32,768 steps per revolution over 4,096 revolutions. The systems provide 1,024 sine/cosine cycles per turn, which after A/D conversion in a servo drive, produces up to four million counts per turn.
