Will US Digital® encoders work in a vacuum?
Our encoders have not been tested in a vacuum. We believe the encoders will
perform just fine in this environment. Regardless, this should be verified with
your own tests.
Will US Digital® encoders work in a radioactive environment?
Our encoders have not been tested in a radioactive environment. We believe the
encoders will perform just fine in this environment. Regardless, this should be
verified with your own tests.
Will US Digital® encoders work in a fluid?
US Digital® offers a housing seal on many of our encoders (HS-option) and
some are available with a shaft seal for harsh environments. Care must be taken
to seal the encoder so fluids cannot enter and damage it. After mounting the
encoder, you may need to seal it with silicone or a similar sealant.
How well do US Digital® encoders work in a dusty environment?
US Digital encoders are fairly robust to dusty environments. The encoders look
at multiple sets of window and bar pairs. Thus a speck of dust at any one window
will be averaged out by the other sets of windows and bars. Because of this
averaging effect, a number of windows can be covered completely and the module
will still not lose a count. The phased array differential modules that read the
disks have plenty of signal margin. An impressive demonstration of this is to
color the disk completely black with a Sharpie pen. The encoder will continue to
work without errors.
What solvents can be used to clean in the vicinity of the encoder modules?
US Digital has found that almost all solvents (besides water) will attack some
part of the encoder module. This includes alcohols and freon-based cleaners. US
Digital has not qualified any solvent to be compatible with the encoder modules.
