Worm Gear Screw Jack Sensing Made Easy & With Zero Maintenance

Newly developed sensor systems offer designers a low cost, highly accurate position sensing solution for worm gear screw jacks. They offer repeatability up to +/- .004” (0.1mm) and a feature easy installation and adjustment of sensors. Best of all, they offer zero maintenance, saving time, money and production.
Systems come with 2 PNP or NPN (normally open) switches. They can, however, be ordered with additional, or normally closed switches.

Ease of Use in the Field

These new sensor systems are specifically designed for easy adjustment in the field. Two magnets are secured to the end of the lift shaft to ensure a positive response once it passes near the position sensor. To adjust techs simply position the lift shaft in the correct position, loosen the locking screw, and slide the sensor to the desired location until the sensor indicates a response. Sensor systems come with 3 slots in the stem cover, and 2 position sensors. Additional sensors can be added to any of the 3 slots, and it is possible to add multiple sensors to the same slot.
