Direct-drive hollow shaft sensing with omnidirectional mounting freedom.
The NP24HS (803) is a conductive plastic hollow shaft potentiometer designed for direct mounting onto rotating shafts without external couplings. Its integrated Omnimount bracket provides flexible installation options, while the precious metal wiper system ensures smooth, noise-free feedback performance.
Built with a compact engineering plastic housing and a 6 mm hollow shaft, it delivers reliable operation and long service life in demanding industrial applications.
