LR-Z Series – Self-contained CMOS Laser Sensor

Laser sensor capable of detecting targets based on both position and contrast (detectable distance: up to 500mm)

1.Best Detection Ability in its Class

Best Detection Ability in its ClassThe LR-Z’s unique U.C.D. Function allows for stable detection of clear, metallic, or dark targets. This series can also detect purely based on distance, regardless of shape, color, or surface finish.

 

 

2.Durable & Long Life

The IP68/69K rating means the LR-Z is ready for the roughest of factory environments. Wash-down, oil spray, and many corrosives are no match for the stainless steel body. Additionally, physical impact or even overtightening are not a concern because of the highly durable design.

 

 

3.Simplified Operation

Simple setup and easy operation are at the core of the LR-Z’s design. With a simple 1-touch teach, calibrating this sensor is straightforward and quick. A highly visible indicator and a 7-segment display make this sensor very easy to use.

 

 

4.Product Applications

Product ApplicationsThe LR-Z has become a standard for both machine builders and product manufacturers. These applications are just a sample of where the LR-Z can be used.
