Product Overview

POMEAS SFS-D7047 is a high-precision spectral confocal displacement sensor with a 47 mm reference distance, ±3.5 mm measuring range, 140 nm repeatability and <±0.7 μm linearity error. Its ±21° measuring angle is among the widest in the series, adapting to strongly inclined surfaces; the Φ52×207 mm body weighing about 784 g suits fixed-station installation.

FAQ

What is the measuring angle of the SFS-D7047?

±21° measuring angle (tested on a standard flat mirror at 1 kHz sampling), among the widest in the series.

What are the range and precision?

Measuring range ±3.5 mm (7 mm total travel), repeatability 140 nm, linearity error <±0.7 μm.

How does it differ from the SFS-D7045?

Precision and range are identical (140 nm, ±3.5 mm); the D7047 has a wider measuring angle (±21° vs ±15.5°) and a longer probe (Φ52×207 mm vs Φ36×84.2 mm). Choose by installation space and surface inclination.
