EMIM differences?

[Albikes]

I've read where the EMIM Rev D, pn 902-0012D, is different from earlier produtions, pn EMIM Mid Rev. B/C .902...0012C. Is this true? Can anyone describe the difference? Are the units interchangable anyway?

Thanks,

Albikes

Al:
Yes, they are different - I believe the magnets are Neo on the "D", and Sa-Co on other versions.
