CL-3000 series - Confocal Displacement Sensor

The CL-3000 Series confocal displacement sensors are compact 1D laser displacement sensors that use a unique method to ensure high-precision measurement on any material or surface. Using a confocal sensor enables stable measurement on materials ranging from dark rubber to clear films without having to adjust mounting or measurement settings. The sensors are designed with only the lens inside the heads, making them both compact and lightweight, which is ideal for installation in narrow spaces or on robots. All electronics are kept away from the measurement location in the optical unit, providing a stable result that is unaffected by heat or electrical noise. Equipped with features like quad spot processing and optical axis alignment, this series is well suited for a variety of industries and applications, including position or thickness measurement, and it can accurately measure on curved, uneven, or even rough surfaces.

* White confocal laser displacement sensor

Advanced Environmental Resistance

Measurement is now possible even at temperatures as high as 200°C 392°F, in ultra-high-vacuum environments, and in explosion-proof areas.

[World's First] Support for Ultra-High-Vacuum Environments*

No organic adhesives

The CL-V020/V050 do not use any organic adhesives in the sensor head, making it possible to minimise outgassing and operate in ultra-high-vacuum environments.

* White confocal laser displacement sensor

First-in-Class 200°C 392°F Heat Resistance

The CL-V020/V050 can handle ambient temperatures of up to 200°C, allowing for use in environments with drastic temperature fluctuations.

Easy Integration in Explosion-Proof Areas

The dedicated feedthrough (OP-88859) allows for easy integration into hazardous areas without extensive work in these locations.
