The () and () mounts include precision electrical limit switches for repeatable absolute positioning without the need for encoder feedback. This is accomplished by measuring the average step size from the left to the right travel limits and vice-versa. Under constant conditions, the step size is fairly repeatable. Additionally, these limit switches serve as a safety feature.

Each Agilis mount – 0.5- and 1-in., with or without a limit switch – is available in a vacuum-compatible version and can be used in 7.5 x 10^-7 Torr environments.
