PBN Series Base Plates

Product catalog summary

Technical Reference Overview: This document provides technical specifications and ordering information for the PBN Series Steel Base Plates used in opto-mechanical applications. These base plates facilitate the connection of positioners with bottom-surface mounting holes to support structures like breadboards and optical tables.

Specifications: The base plates are available in metric measurements but are compatible with both English and metric models. They are designed to mount stages with bottom-surface mounting holes to optical tables and are compatible with UMR, MVN, and UTR stages.

Model Specifications:

M-PBN3: Features include 2 holes with M3 clearance and 4 holes with M3 threading, suitable for UMR3.5 stages.
M-PBN5: Includes 4 holes with M3 threading and clearance, compatible with UMR5 and MVN50 stages.
M-PBN8: Contains 4 holes with M4 threading and clearance, designed for UMR8 and MVN80 stages.
M-PBN12: Features multiple holes with M4 and M5 threading, suitable for UMR12 and MVN120 stages.
M-PBN16: Includes 4 holes with M6 threading and clearance, compatible with UTR120 stages.

Ordering Information: The document lists compatible linear, vertical, and rotation stages for each model, ensuring users can select the appropriate base plate for their specific application needs.

Additional Resources: CAD files for these base plates are available on the Newport website, providing further technical details and design support.
