Magnetic Spindle Encoder Adds Safety Features

Improvements to the company’s ERM 2200 and 2400 series of magnetic modular angle encoders accommodate the growing trend requiring “Functionally Safe” axes (an EU standard) on machines. HEIDENHAIN has improved its ERM angle encoders to permit mounting to include a mechanical fault exclusion of these encoders, a key requirement in making a machine Functionally Safe. These changes include deeper, more robust fastener mounting holes in the reader head and fastener holes in the scale drum itself.  While making these changes, the company also consolidated the reader head designs into a single, smaller footprint so the new heads will drop into the old designed space.  More details and specs are available as well as a datasheet and product diagrams.
