User Application Notes:
• The VS3...XLP series should be used for general sensing applications like packages, small parts, mirror-like surfaces, or documents. They are most effective when used with the supplied micro-prism reflector.
• When using glass bead tape, (e.g., 3M model 6870), non-polarized models (...XLV) must be used. These models should also be considered when a glass lens (as in the LP models) is not permitted in the sensing environment.
• For non-polarized sensors, an object’s surface reflection (e.g., polished stainless steel), may be more reflective than low-grade retro-reflective tape, and “bright” object transition may never be detected by the non-polarized sensor.

VS3 Series Overview
VS3 Series miniature self-contained sensors are designed for retroreflective sensing in small areas previously accessible only to remote or fiber optic models. Typical applications include mounting on small feeder tracks, packaging machines, and conveyors, where larger sensors will not fit.
The coaxial optics of the VS3 allow the retroreflective target to be placed as close to the sensor lens as needed – there is no “blind” response area, as is typical of most retroreflective sensors. The VS3 is supplied with a Banner model BRT32X20AM retroreflective target (see right). The specifications shown on page 1 assume use of this target.
Other retroreflective materials may be substituted. For example, using the standard BRT-3 target, the range becomes 400 mm (16"); standard BRT-THG retroreflective tape yields a 150 mm (6") range. Contact Banner Engineering for sensing performance when using other retroreflective targets.
