Me chan i cal Char ac ter is tics: • Shaft Rotation: Continuous in either direction, 300RPM maximum
• Ter mi nals: P/C Type: .025” (.64mm) by 0.12” (3.05mm) thick brass, gold plated to facilitate soldering
• Cable Type: • Four lead rib bon cable, color-coded, with .050” (1.27mm) spacing • 28AWG stranded
copper wire, .039” (.99mm) diameter • Strength: Terminals withstand 2 pounds push and pull and a
90° bend.

Edit: I just looked at the data sheet and it does, indeed, have a max RPM of 30,000. I think the max RPM described in the data sheet is in reference to the sensitivity/resolution as these things are more like potentiometers. They are made for manual manipulation, so the datasheet is specifying what happens if somebody twists it really fast. I do not believe that these encoders are made for continuous rotation because they have a plastic on plastic wearing surface. You could install it, however, then take bets on how fast it will fail.
