he RL500 Hollow Shaft Resolver is intended for those applications where there is a projecting 5/8" (15.88 mm) diameter shaft (machine shaft, double-ended motor shaft, etc) available at the point where the user wishes to take rotational readings. Instead of having to make provisions to install a traditional resolver, which has to be installed with a bracket and coupled to a shaft on the machine, as long as there is a 3" (76.2 mm) shaft projection, the RL500 can be mounted directly to the machine.

New no factory box, some scuffs
