250nm Short-Body Confocal Displacement Sensor with 54.5mm Reference

Product Overview

POMEAS SFS-D8054L is the short-body version of the SFS-D8054 with a 54.5 mm reference distance, ±4 mm measuring range, 250 nm repeatability and <±1.6 μm linearity error. The Φ23×48.5 mm probe weighing only about 29 g has an even shorter axial length for space-constrained installations; the non-contact optical method handles highly reflective, transparent and soft surfaces.

Technical Specifications

Applications

Ideal for axially constrained multi-probe arrays, electronic component displacement and height inspection, transparent material thickness measurement and long-working-distance inspection in confined installations.

FAQ

How does the SFS-D8054L differ from the SFS-D8054?

Measurement specifications are identical (250 nm, ±4 mm, 54.5 mm reference); the difference is probe length: 48.5 mm for the D8054L vs 50 mm for the D8054, fitting axially constrained installations.

What is the weight?

Only about 29 g (Φ23×48.5 mm), one of the lightest models in the SFS series.

What are the range and precision?

Measuring range ±4 mm (8 mm total travel), repeatability 250 nm, linearity error <±1.6 μm.
