The SICK SRS/SRM50 Series Motor Feedback System is an optical high-resolution feedback system with hollow, solid, tapered and plug-in shaft designs. These systems come in singleturn and multiturn configurations, with 1024 sine/cosine periods per revolution. This series of products are well suited for a variety of servo drive applications. The mechanical design involves a precise metal code disk and the largest possible distance between the two ball bearings, which simultaneously offers high shock and vibration resistance. SRS50S and SRM50S variants include SIL2 / Pl d saftey level certification.
