PI (Physik Instrumente) has extended its product portfolio for industrial positioning solutions with the L-412 and L-417 linear stages.
The individual types of the series differ in their width, 116mm (L-412) and 166mm (L-417), and are suitable for loads to 40kg and 45kg respectively. The travel ranges start at 52mm and continue up to 813mm; the maximum velocity is 300mm/s. A vertical operation is also by using an optional brake. The stages are driven by high-performance, energy-efficient synchronous servo motors which, depending on the version, work at supply voltages from 75V to 320V.
The robust, reliable motors position accurately up to a few micrometres thanks to high-resolution incremental or absolute encoders; they cover large rotation speed ranges and have high torque overload capacity. High torque and low inertia ensure high dynamic operation. The cable exit on the motors is flexible; this makes it easier to position the cable in the machine. The drive screw can be relubricated directly from the outside, therefore simplifying maintenance in hard-to-reach environments.
Specially shaped hard covers protect against hot particles resting on the stage. In addition, side sealing and air purge connections (providing an internal positive pressure) in conjunction with the cover, prevent the intrusion of dirt or hot particles into the stage.
