Minimum distance from slider
3.7.1 Minimum distance from slider to slider
The sliders are made of neodymium magnets and have a strong magnetic attraction.
It must be kept a minimum distance between the sliders. This minimized the risk of bruising and secondly,
the sliders do not influence each other through their magnetic fields.

3.7.2 Minimum distance from slider to metallic parts
When installing linear motors in modules with metal parts near the slider, undesired forces can arise due to
magnetic attraction or eddy currents. These generally manifest as erratic and jerky positioning, or reduced
dynamics of the linear motor. In order to avoid this, minimum distances between the slider and any metal
parts are to be observed whenever metal materials are used nearby.
