Compact 1x1 loaders that use electricity. They are able to use separate filters on each belt lane, and can stack items on belts if stack inserters are available.
This only applies to 5Dim recipes that 5Dim adds. The base game has no recipe for loaders.
It is controlled by a mod setting. You can choose to keep the 5Dim loaders if you wish. They are redundant and less capable (no stacking, no split lanes). But if you want to continue to use / keep them change the mod setting to keep 5Dim's loaders.
