Aero-Motive® Positioners


The Aero-Motive Positioner supports light-duty assembly tools in work areas to eliminate clutter, reduce repetitive motion, and minimize operator fatigue


Molex Aero-Motive® Positioners offer a fast, easy-to-use, tension adjustment and cost effective method to support assembly tools for manufacturing. Positioners support tool weight ranges from 0.5 to 4.5 kg (1 to 10 lbs.) with a cable travel distance of 1.4 m (4.7'). This positioner supports tools in a work area to eliminate clutter, reduce repetitive motion, minimize operator fatigue, and hold the object in a desired position for light-duty use.

Aero-Motive® positioners use an adjustable friction brake to place and hold an object in any position to support the weight of the suspended tool or object. The object can be moved downward with very little effort, depending on the adjustment; however, the full weight of the object must be lifted to move it upward.
