Technical Highlights
Long Reference Distance
The 150 mm reference distance provides more installation space between the sensor and the measured object. This makes it easier to integrate lighting, fixtures, moving parts, and other inspection components.
Wide Measuring Range
With a ±35 mm measuring range, the sensor provides a total measuring span of 70 mm. It is suitable for objects with larger height differences or position variations.
Stable Precision Measurement
The SFS-D700150 offers 1550 nm repeatability and a linearity error of less than ±2 μm, supporting stable displacement, height, and surface profile measurement.
Non-Contact Optical Measurement
The chromatic confocal measuring principle allows the sensor to measure without physically touching the object, helping prevent surface damage and mechanical wear.
Flexible Measurement Angle
The sensor supports measurement angles up to ±5.5°, making it suitable for surfaces that may not be completely perpendicular to the sensor.
Typical Applications
The SFS-D700150 can be used in a wide range of industrial measurement and automated inspection applications, including:
- Height and displacement measurement
- Surface profile inspection
- Step height measurement
- Position and dimensional inspection
- Metal component inspection
- Mold and machined part measurement
- Automated production line inspection
- Large-range surface variation measurement
- Precision component quality control
- Non-contact measurement in limited-access areas
