Geared potentiometers are used in various applications where the positioning feedback of slow moving shafts is required. These potentiometers sometimes come with variable gear ratios to increase the number of revolutions they can measure. The mechanical complexity of these contact based potentiometric systems have drawbacks in terms of flexibility and reliability.

Zaber’s A-BLQ-E series products are computer controlled, belt-driven linear stages with integrated stepper motors and controllers. A built-in rotary encoder allows closed-loop operation with slip/stall recovery features. They are stand-alone devices requiring only a standard 48 volt power supply for operation. A knob at the end of the stage permits smooth manual control; press and hold to switch between velocity and displacement mode and turn to move the stage.
