Hmmm, intrinsically safe is not so easy for externally powered devices.
Not only must the encoders be IntSafe, but the power source must
also be rated IntSafe for use with the specific encoder, as well as
the wiring, conduits, etc. I suspect you need to do serious research
with Rockwell/Allen-Bradley, BEI, Heidenhain, or one of the other
industrial encoder manufacturers. I'm sure they have all faced this
at one time or another.
