Set-up
for use with non-reflective reels/spools
A two-component transmitter-receiver configuration creates
a steady beam of light, or "light barrier" effect.
The system is positioned such that the spool flanges interrupt,
or break, the light barrier thereby triggering reversal of
the traversing direction of the drive head. Because the system
does not rely on the reflective properties of the take-up
spool, it can be used with virtually all spools and reels
regardless of their composition or reflective qualities. The
system is ideal for use with metal, wooden, or plastic spools,
or other spools with zero or low reflectivity.
Set-up
for use with reflective reels/spools
Optical sensor scans the inside edges of the spool flange
and signals controller to reverse.
