The options when specifying sensors for long-range object detection or positioning usually boil down to two alternatives: optical sensors using either infrared or visible-red light and ultrasonic.

Designed to accurately detect shiny objects, the VS3 series retroreflective sensors are said to eliminate the blind response area associated with conventional photoelectric sensors. Miniature in size, ...

Company Announcement - The calibrated abeam optics on the Leuze PRK 18B Series sensors ensure precise striking of even the smallest reflectors, eliminating the need for time consuming alignment after ...

With both discrete and analog outputs, the BOL 27K retroreflective photoelectric sensor projects a measuring line of light on to a strip of special reflective tape, which it uses to measure and locate ...

Banner Engineering introduces the WORLD-BEAM® QS18 Adjustable-Field Foreground Suppression Sensors, designed to reliably detect objects regardless of color, reflectivity, surface irregularities or ...

Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

The usual way of detecting objects of varying shapes, heights, or positions has been through the use of an array of single-beam photoelectric sensors or a thru-beam light grid: a photoelectric array ...
