The RL501 Pancake Resolver is intended for those applica-
tions where there is a projecting
1
/
2
" (12.7 mm) diameter shaft
(machine shaft, double-ended motor shaft, etc.) available at
the point where the user wishes to take rotational readings.
Only 1" (25.4 mm) thick, the RL501 can be installed in appli-
cations where space is very constricted. Instead of having to
make provisions to install a traditional resolver which has to
couple to a shaft on the machine, as long as there is a 1" (25.4
mm) shaft projection, the RL501 can be mounted directly to
the machine.
