Laser light sensor helps quality control
Pepperl+Fuchs laser light section sensor LineRunner LR300 can track corrections, do edge or gap measuring, provide volume determination, and do tolerance checks.
Pepperl+Fuchs high-performance and safe laser light section sensor is the LineRunner LR300. Tasks of and demands on modern vision system solutions include correction tracking, edge or gap measuring, volume determination, and tolerance checks. In the laser light section process, a line is projected on an object and recorded by a camera at a certain angle. Using the triangulation principle, it is possible to determine the necessary height and width information.
The LR300 uses this method and can compensate (due to a refined lighting system) even very difficult color and contrast lines. Safe laser protection class 1 saves costs for securing workstations, which would otherwise arise in the case of a higher laser protection class.
Via its Ethernet interface, the LineRunner 300 provides width and height data in millimeter dimensions and thus can be directly connected to the VMT systems to form a reliable and secure overall unit.
The VMT LineRunner system solution has:
- No impact of extraneous light due to IR laser measurement
- No impact due to changing background images
- No restrictions in the choice of the measuring locations owing to object geometry
- No impact due to changing surface appearances (color, texture)
- No additional protective measures are required owing to laser protection class 1
- Only Ethernet and voltage supply lines (no video lines attached to the robot).

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
