Banner Engineering has introduced the latest addition to its family of World-Beam sensors, the QS18 Adjustable-Field Sensor with Class 2 laser. The unit provides increased sensing capabilities with a cut-off range of 50-250 mm. It also offers reduced excess gain within 20 mm of the sensor, making it less susceptible to the effects of lens contamination in challenging industrial environments.
World-Beam QS18 sensors feature outstanding optical performance and excellent sensing repeatability in a universal compact sensor package, a narrow effective beam (1 mm spot size) makes it ideal for small-object detection and precise position control. The visible red laser accurately detects objects of relatively low reflectivity, ignoring background objects beyond the cut-off point. In addition, cut-off is easily adjusted using the 5-turn adjustment screw on the sensor top. With its compact, sealed housing, bright LED operating status indicators and versatile mounting options, the QS18LAF250 delivers an exceptional sensing solution for small or difficult-to-reach areas.
The design uses the optical triangulation principle to detect objects of varying colour accurately inside the cut-off distance, ignoring specular or shiny objects in the background. This feature, combined with the sensor’s compact housing and precise sensing beam, provides an exceptional solution for applications where detecting minute features is critical, including the following:
