HEIDENHAIN RCN 223M Absolute Angle Encoder
The HEIDENHAIN RCN 223M is an absolute angle encoder with integral bearing and a Mitsubishi high-speed serial interface, for rotary tables and machine axes with Mitsubishi controls. Legacy model: it is not in HEIDENHAIN's April 2015 angle encoder catalog, which lists the RCN 2000 series. Ask AMI about repair, replacement or sourcing for your exact unit; availability and the right replacement path are confirmed before quoting. This page does not claim stock.
