Product Features

1. IP67 high protection level:
Can be used in environment with a lot of dust and water.
The internal mounting holes have metal sleeves, which can withstand greater mounting stress.
2. Ultra-high stability, bringing you ultimate measurement experience:
Built-in original SPA algorithm SUPER-POINT-AIGORITHM (original in the industry) Even if it deals with workpieces of different colors and the imaging spot is different, the point can be accurately selected to ensure stability and reliability of the sensor output
3. The most cost-effective laser displacement sensor:
The highest resolution can reach 0.25 μm, and it can be taught by PC-side upper software, which is simple and easy to operate. The series corresponds to high-precision detection of 30-140mm. You can choose according to the site situation.
