140nm Confocal Displacement Sensor with ±3mm Range

Product Overview

POMEAS SFS-D6040 is a large-range spectral confocal displacement sensor with a 40 mm reference distance, ±3 mm measuring range, 140 nm repeatability and <±0.72 μm linearity error. The ±3 mm range suits surfaces with larger height variation, while the compact Φ30×65.3 mm body weighing about 112 g is easy to integrate. The non-contact optical method handles highly reflective, transparent and soft surfaces.

FAQ

What are the range and precision of the SFS-D6040?

Measuring range ±3 mm (6 mm total travel), repeatability 140 nm and linearity error <±0.72 μm, one of the larger-range models in the SFS series.

What are the body size and weight?

Φ30×65.3 mm, weighing about 112 g, compact and easy to integrate into automation equipment and motion platforms.

Why is the reference distance important?

The 40 mm reference distance is the nominal working distance from the probe to the target. A longer distance gives more mounting and travel clearance, reducing collision risk and suiting surfaces with larger height variation.
