PI (Physik Instrumente) has debuted a new compact linear stage, the L-509. Providing high precision linear motion with minimized runout, this positioner delivers performance and reliability at minimized cost.
Despite its compact dimensions, the stage can handle payloads of more than 20 lb. Available with travel ranges of 26 mm (1 in.), 52 mm (2 in.), and 102 mm (4 in.) and velocity to 20 mm/sec, the L-509 delivers high accuracy and smooth motion with unidirectional repeatability down to 0.1 microns. Long service life and excellent guiding accuracy with minimum backlash are guaranteed by the precision crossed roller bearings with anti-creep cage assist. For the highest precision requirements, a linear encoder with 1 nanometer resolution is available.
A compact DC servomotor with gearhead is offered for high torques and resolution, while a 2-phase direct-drive stepper motor delivers higher velocity. Encoder options include an integrated rotary sensor mounted on the motor shaft and the above mentioned integrated linear version that provides direct position measurement not influenced by mechanical play or hysteresis in the drive train.
Noncontact, optical limit switches and reference point switches with direction sensing in the middle of the travel range simplify use in automation tasks.
The L-509 is suitable for a range of applications including beamline systems, automation, seminconductor applications, photonics, bio-nano-technology, metrology, microscopy, micro-manipulation, and cleanroom applications, among others.
