MUNICH, May 30, 2013 — The ECR5050 bearing-based rotator from attocube systems AG allows clockwise and anticlockwise rotation with torques up to 4 Ncm for positioning applications. The device is available with an integrated optoelectronic position encoder featuring a sensor resolution of 10 μ° and a repeatability of 1 m°. Open- and closed-loop modes can be achieved using the ECC100 controller. Interfaces such as the USB, TCP/IP and EPICS via Ethernet, TTL and AquadB triggers, DLL and LabView enable the implementation of the positioning units in almost any environment. The system operates in ambient conditions; for operation in high-vacuum and ultrahigh-vacuum environments, stainless steel positioners with vacuum feedthroughs are available.
