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.
