Velmex BiSlide® Assemblies come standard with two adjustable limit switches mounted in a track on the side rib of the assembly to prevent over-travel.

They also can be used to send an event signal.

BiSlide limit switches are referenced by either a “-21” or “-31” at the end of the model number.

It is possible to purchase motor-driven Velmex stages without limits, however, it is not recommended and it may effect the warranty should you incur any damage.

An optional third limit switch can be added between the two standard limits and used as an adjustable home switch. This would require an additional controller to operate.

On Parallel-Coupled BiSlide Assemblies, the limits would be eliminated from one of the two linear stages that comprise the assembly.
