A button-like capacitive sensor, the Model HPB Series, is available in miniature sizes. These non-contact displacement units come in thicknesses of 0.065, 0.093, and 0.15 in., offering access to difficult inspection areas on metallic parts without the need to touch the product surface.

The unit can be installed on gauge heads, creating a rugged manufacturing or inspection tool for displacements, gaps, and thicknesses.
