 |
Long distance/visible laser beam with small spot! |
Feature
- Easy to install because visible laser beam
- High response time, 0.25msec. or less
- IP67, water-proof structure
Applications
Diffuse-reflection type |
Retro-reflection type |
Small objects can be detected because of small spot and thin beam |
Small space between the objects in the high speed line can be detected |
|
|
Through-beam type |
|
Objects with 2mm in diameter can be detected at 5m |
|
|
|
Caution
This product is emitting visible laser beam and is classified as Class 1/2 by JIS C6802/IEC Laser Safety standard. When exporting to USA, US laser control, FDA(Food and Drug Administration) is applied. Please ask us in details. |
