PRODUCT OVERVIEW

Selection starts with the operating requirement.

Use SMG20 as a starting point for constrained stages, scientific instruments and semiconductor-oriented motion platforms. Final speed must be evaluated against the selected resolution and output frequency.

Open technical itemExact vacuum grade, RGA and outgassing data require supplier confirmation.

ENGINEERING VALUE

What this platform brings to the design.

01

Compact integration

A 5 × 12 × 21 mm readhead supports space-constrained mechanical layouts.

02

Configuration-aware performance

Resolution and maximum speed are treated as linked choices, not independent headline values.

03

Scale flexibility

Source documentation covers both stainless-steel and glass scale configurations.
