Absolute sensor that can be built into a narrow path or slim cylinder.
The sensor has a very thin diameter of φ4mm and can be embedded in small-diameter, thin cylinders. The flange part contributes to space-saving with a thickness of less than 10mm. The sensor has an absolute output with a resolution of 1/2000 of the stroke. Pressure resistance: 21MPa (pressure test: 35MPa). Customizations such as flange shape and cable exit direction can be accommodated from a single unit.
