Optics solve object and position sensing problems
Designed for a variety of applications, optical sensors are ideal for positioning tasks such as level detection, material jam control or detection needing expanded background suppression.
The brochure illustrates how Balluff continues to develop products for the food and packaging industry, highlighted by the new series BLG 1 Light Grid, which allows detection and measurement of objects - even over large areas, said the company.
The BLG 1 photoelectric light grid is designed for any area of automation technology but is said to be suitable for the food and packaging industry.
Working on the basic principle of a through-beam sensor, infrared LEDs are used as the light source.
Amongst the key applications are detecting, counting and measuring various objects, for example when packages need to be selected or checked on a conveyor.
The height or width of objects can be determined and used as the basis for a decision with respect to further processing, claimed Balluff.
The BLG 1 Light Grid can detect objects as small as 4mm in diameter.
Two different outputs are available on the system.
The analogue output provides a voltage signal proportional to the number of interrupted beams, with the signal directly processed in the controller.
A single light grid - consisting of emitter and receiver - allows numerous objects to be detected.
The digital output always becomes active when at least one light beam is interrupted.
The output is said to be suitable for counting objects and also enables planar presence monitoring.
Balluff added that the product can be installed and operated with no special technical expertise.
Installation is claimed to be simple, and alignment non critical.
The integrated power and diagnostic indicators make start-up and troubleshooting easier, whilst the housing is made of anodised aluminum and is suitable for even harsh environmental conditions.
The light grids are available with controlled heights of 100mm, 150mm and 300mm and ranges of 850mm and 2,100mm.
