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 Leuze RK46C-VarOS retro-reflective photoelectric sensor is capable of detecting objects over an operating range of 0.4 to 5.2 metres, with a light band width of 45 to 50 mm.

Photoelectric sensors and light curtain sensors are among the most commonly used sensing devices in factories. Photoelectric ...

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 ...
