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.
