Retroreflective Models
Excellent for sensing small items where opposed-mode sensing is not possible.
Recommended for relatively clean environments where substantial excess gain
is not required. Polarized models filter out unwanted reflections.

Convergent-Mode Models
Convergent-mode sensors feature high excess gain and can detect objects of low reflectivity.
They are a good choice for counting radiused objects with no space between them, for
accurate position sensing, and for sensing clear materials that travel near the beam’s focus.

Convergent Mode
* 9 m (30') cables are available by adding suffix “W/30” to the model number of any cabled sensor (e.g., QS12VN6CV10 W/30). A model with
a pigtail QD requires a mating cable (see page 7).
**Range specifications for retroreflective and polarized retroreflective sensors are largely dependent on target size and design.
