CAMBRIDGE, UK The MES3 series is CUI's latest line of high performance micro optical encoders, the world’s smallest shaft-type optical encoder according to the company.
The MES3 has a 5-mm body diameter and a 1.5-mm shaft diameter. The series is well suited for use in medical and robotics applications where size is critical. Smaller than a pencil eraser, it is able to provide very precise position and speed information in motion control systems, competing in performance with encoders more than three times its size.
The MES3 is available with resolutions of 64 or 1024 PPR with an option of line driver or open collector output signals. Additional features include an operating temperature range of 0 to 60 degree Celsius and a maximum speed of 6,000 RPM. Lead time is 4 to 6 weeks
