SNIP- In my quest to get replacement encoders, Heidenhain told me that SSI encoders are becoming scarce as Endat has become a much more popular interface for encoders (or at least the ones they sell). Dave They (perhaps

Also, CUI has added a version of their AMT encoders that produce commutation signals as well as traditional ABZ, if you need this on a brushless motor. Jon -- vRanger cuts backup time in half-while increasing security.

The guys I have been talking to are the Encoder Technicians - not the marketing guys so their observations regarding SSI vs Endat volume is simply what they see as being popular from a Heidenhain perspective. I don't think that BISS encoders are sold by Heidenhain since they are pushing Endat,
