SICK SLG-2 User Manual

SLG-2 with 3-fold crossover SLG-2 with 9-fold crossover
•
The cross-beam function is only useful for object detection (NBB ≥ 1).
•
Due to the crossed beams, the cross-beam function is very useful for detecting
very narrow but wide objects (e.g. metal sheets).
•
Use of the cross-beam function increases the response time.
•
With the cross-beam function, a minimum distance needs to be maintained
between sender and receiver. The minimum distance depends on the aperture
angle of the light grid.
NOTE
Detailed information on resolution, response times and minimum distances can be
found in chapter chapter 11.
Minimum object size (MDO):
•
MDO 3-fold cross beam @10 mm beam separation = up to 9 mm
•
MDO 9-fold cross beam @10 mm beam separation = up to 6.5 mm
NOTE
Detailed information on the MDO in cross-beam mode can be found in chapter
chapter 11.
Resolution / minimum object width (MOW)
For the detection of very flat objects, the cross-beam function with the 7x or 9x cross-
beam option is suitable. Due to the different angles of the beams between the sender
and receiver, reliable detection of even an infinitely flat object with a certain minimum
width is possible.
Reliable detection depends on several factors:
•
Beam separation
•
Distance from sender and receiver
•
Minimum width of the “infinitely” thin object
•
Location of the object between sender and receiver (better resolution in the mid‐
dle range)
MOW = minimum object width
Detailed technical information on the detection capability and the minimum object
width can be found in chapter 11.1.3.
