Slim shape with stem diameter of Φ8 mm and high durability ball spline bearing.
Our unique signal processing technology enables measurements that require high accuracy and real-time performance.
- Measuring range: 5 mm, 12 mm, 30 mm
- Maximum resolution: 0.1 µm, 0.5 μm
- Accuracy: 1 µm p-p to 1.7 µm p-p (Depends on the model)
- Maximum response speed: 80 m/min (resolution 0.1 µm), 250 m/min (resolution 0.5 µm)
- Bearing structure: Improved sliding performance through the use of highly durable ball spline bearings
- High durability: 320 million sliding cycles or more (under continuous evaluation as of January 2021)
- Protection grade: IP67 (straight type / right angle type with air tube)
- Built-in reference point
- Output signal: A/B/reference point (Voltage-differential line driver output)
- Flange type is also available for strong fixing.
