For precise position display, a range of digital position indicators are available for use with ActionJac™ Worm Gear Screw Jacks. These indicators measure the rotation of the input shaft and display a corresponding position in a counter window. The display value per input shaft revolution is variable and is achieved through a series of gear reductions configured to accommodate different jack ratios, lift shaft leads and travel distances. Contact Nook Industries to determine actual readout scaling available for your application. Not for use with motorized applications. Long strokes may result in counter "rolling over."
- Determine Mounting Position
- Count Increase or Decreases with Extension of Shaft
Please see (See Image 2 in Figure 1 Below) for example and example of counter designations.
CAUTION: Consult Nook Engineering when adding a counter. Some jack configurations may have limited travel.
Please see (See Image 3 in Figure 1 Below) for detailed product codes and diagrams.
