Positioning Stage

For precise positioning tasks in precision fabrication and automation, PI now offers the M-417 stage with a repeatability of 0.5 µm over a 500 mm travel range The drive of the M-417 comprises an efficient ActiveDrive DC motor with integrated 24 V amplifier that acts on the ball screw. Thanks to this structure, the stage achieves a velocity of 100 mm/s and is at the same time designed for high duty cycles. The recirculating ball bearings allow for a very high guiding accuracy of 100 µrad over the entire travel range. An incremental, motor-shaft-mounted rotary encoder controls the position with a unidirectional repeatability of 0.5 µm. The stage is 120 mm wide and 56 mm high. Its stress-relieved aluminum base ensures the stage's high stability.
