Magnetic spindle encoder designed for functional safety

Heidenhain Corp. has announced updates to its ERM 2200 and 2400 series of magnetic modular angle encoders for functional safety. In keeping with the growing trend requiring functionally safe axes (an EU standard) on machines, the company has updated the encoders to permit mounting to include a mechanical fault exclusion, 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. Reader head designs also have been consolidated into a single, smaller footprint so the new heads will drop into the old designed space.
