Background Suppression (BGS)
Coaxial Polarized Retro-reflective (Transparent Object Sensing)
Detects objects of different colors
The improved sensing ability detects objects of different colors such as black and white more accurately.

Coaxial optical structure and narrow beam ensure stable detection;
unaffected by narrowing, inclination or shaking of a bottle.
Because the SA1E-X co-axial
polarized retroreective model
does not have blind zone,
where the reected light
misses the light receiving
element, like the SA1E-P
polarized retro-reective type,
the SA1E-X can be used in
applications where objects
pass near the sensor.

Ignores the background and
detects the objects only
Smaller beammakes it possible to detect
small objects and narrow gaps between
theobjects. The upgraded model is also
less affected by the object colors.
