Improving Linear Actuator Design Flexibility with Non-Contact Position Sensing

Thomson Industries Inc.

One of the most common methods for determining where the actuator is in its stroke uses potentiometers, also called pots, to track changes in electrical resistance or related voltage drops.

Electric Actuator Advancements Expand Options for Replacing Hydraulic Cylinders

Electric actuators can provide a lower total cost of ownership compared to hydraulic cylinders, as well as increased control and precision capabilities.

Figure 1: This H-Track electro-hydraulic linear actuator from Thomson can handle up to 4,800 lbs. (21 kN) of force in a clean, compact enclosure that also has shock handling capabilities comparable to a hydraulic system.
