Accuracy in Small Steps: New Precision Linear Stepper Stage from PI
November 2015, Auburn, MA – Precision positioning systems solution specialist PI (Physik Instrumente) L.P. presents the L-511 linear stage series featuring minimum incremental motion as small as 0.02µm. With travel ranges to 155mm (6 inches), this 2-phase micro stepper motor platform is ideal for precision positioning demanded by science and industry, especially with high duty application cycles. Vacuum compatible versions are available.
Flexibility, Recirculating Ball Screw and Bearings for Durability, Performance, and Precision
L-511 stages come in travel ranges of 52 mm (2“), 102 mm (4“), and 155 mm (6“). They are designed with recirculating ball bearings for high-load capacity and durability at demanding repetitive cycle rates with velocities up to 45mm/sec and despite the compact design can easily manage loads to 100N (22lbs). The precision ball screw drive unit with 2mm pitch is nested in a stress-relieved aluminum base for the greatest stability.
Multi-directional automation tasks are sped up with the addition of noncontact, direction-sensing optical reference point switches located in the middle of the travel range. Noncontact limit switches are integrated as well, to protect the mechanical structure.
Wide Dynamic Range
The micro-stepped motors provide extremely smooth motion with a high dynamic range from microns/second to 45mm/second. To achieve the ultimate in control and positioning accuracy, the L-511 is available with a centrally located high-resolution linear encoder providing one nanometer resolution if operated with the MC Hydra controller. PI offers a large variety of controllers from cost efficient single-axis open-loop units to multi-axis closed-loop controllers for parallel-kinematic motion systems.
