The ERM 2x0 series of magnetic, modular rotary encoders for use on large shafts such as the C-axis of lathes, spindle drives, and electric motors is better than ever. Recently redesigned to benefit even more applications, this product enhancement includes a reduced scanning head size and improvements to the measuring standard. The scanning head features a compact design and has been reduced from 40 mm to 20 mm. Also, the maximum permissible speed of the encoder could now be considerably increased with the new design, for example to 40,000 rpm from the past maximum speed of 24,000 rpm. The series also offers a larger scale drum since a lot of applications require larger hollow shafts.
