Electronic handwheel

Description
The portable electronic handwheel is intended for use in conjunction with machines. A
magnetic bracket and spiral connection cable can be found on its enclosure. The magnetic
bracket (retaining magnet) enables the handwheel to be attached to metallic surfaces.
The portable electronic handwheel is an incremental encoder that generates signals according
to how the manually operated wheel is rotated. The handwheel's magnetic latching facility
makes for an extremely precise incremental process. The axis selected via the control can be
positioned so that the axes are parallel. The portable handwheel offers a PPR count of 100 S/
R.
