Narrow pin interval detection
Stable detection of 5 mm gaps that are not
detectable by previous regression reflection
models.
We significantly increased the S/N ratio to enable a stable detection of PET bottles and vari-
ous other transparent containers

Wide detection range. Stable detection
even at long distances.
Use of hyper-point LED as light source
(1/2 light emission diameter of previous models)
enables stable long-distance detection.

Adoption of the coaxial retroreflective model
Stable detection can be carried out also to the transparent bottle of various form and surface states.
