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.

A typical reflective object sensor consists of an infrared light emitter diode (IRED) and an NPN silicon phototransistor mounted side-by-side on parallel axes in a compact black plastic housing. The ...

When you’re designing miniature optical switches, reflective sensors are your best friend. They streamline the interaction between humans and machines in an elegant and intuitive manner. These sensors ...

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.

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 ...
