Zaber's A-LST-C linear stages include flexible stainless steel dust covers and built-in controllers. They are stand-alone units requiring only a standard 48V power supply. A manual knob at the end of the unit permits manual control - press and hold to switch between velocity mode and displacement mode, turn to move the stage, and press to stop. The stages connect to the RS-232 port of any computer and can be chained with up to 254 units per chain. They can also be chained with any other A-series or T-Series products. Convenient 6-pin mini din cables on the unit allow for direct interconnection between units in close proximity. For longer distances, standard cable extension can be used.
