Description
Pacific Precision ST-SLO4-R-PO25 Linear Slide Heidenhain LID 311/10 Encoder 4in
The Pacific Precision Laboratories (PPL) ST-SLO4-R-PO25 is a motorized closed-loop linear slide with approximately 4 inches of travel. This unit is configured without a lead screw and is fitted with a Heidenhain LID 311/10 linear encoder reading a Heidenhain MSA 6706 glass scale for precision position feedback. It was deinstalled from a custom-built semiconductor inspection system and is being sold as-is for parts or repair.

Applications
Motorized closed-loop linear slides of this type are precision positioning components used in semiconductor inspection systems, wafer handling equipment, automated optical inspection (AOI) platforms, and research instrumentation requiring repeatable, encoder-verified linear motion. Pacific Precision Laboratories produced a range of precision motion stages widely used in semiconductor fabrication and inspection environments from the 1980s through the 2000s. The Heidenhain LID 311/10 is a compact incremental linear encoder designed for integration into motorized stages, providing high-resolution position feedback via a glass scale — a combination common in applications demanding sub-micron repeatability. Two slides of this type can be stacked to form an XY positioning table, as shown in the reference photos.
This Pacific Precision ST-SLO4-R-PO25 closed-loop linear slide is being sold AS-IS for parts or repair. It was deinstalled from a custom-built semiconductor inspection system. No functionality is guaranteed, and it has not been verified operational. The photos show two slides configured as an XY table for reference — this listing is for one slide only. Please review all photos carefully and contact us with any questions before purchasing.
