Adjustable-Field Sensor features visible Class 2 laser.
Press Release Summary:
Offering cutoff range of 50-250 mm, WORLD-BEAM® QS18LAF250 delivers background suppression sensing, and has narrow effective beam with 1 mm spot size, making it suited for small-object detection and precise position control. Cutoff point is adjusted using 5-turn adjustment screw on sensor top. In addition to sealed housing and LED status indicators, sensor features reduced excess gain from 0-20 mm, making it less sensitive to lens contamination in industrial environments.
Original Press Release:
World-Beam® QS18 Adjustable-Field Sensors Now Available with Visible Class 2 Laser for Enhanced Sensing Capability
MINNEAPOLIS, MN-August 20, 2007-Banner Engineering Corp. announces the latest addition to their versatile family of WORLD-BEAM® sensors, the QS18 Adjustable-Field Sensor with a Class 2 laser (QS18LAF250). The QS18LAF250 provides increased sensing capabilities with a cutoff range of 50 to 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. The QS18LAF250 delivers reliable background suppression sensing, and pricing starts at $179.
WORLD-BEAM QS18 sensors feature outstanding optical performance and excellent sensing repeatability in a universal compact sensor package. The QS18LAF250 has a narrow effective beam (approximately 1 mm spot size), making it ideal for small-object detection and precise position control. The visible red Class 2 laser accurately detects objects of relatively low reflectivity, ignoring background objects beyond the cutoff point. In addition, cutoff point 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 QS18LAF250 is a background suppression sensor that builds upon the strong performance of Banner's WORLD-BEAM adjustable-field products," said Dennis Smith, Banner Engineering product manager. "The sensor's Class 2 laser provides a longer sensing range with high peak excess gain where it matters most. The optical design also introduces reduced excess gain close to the sensor face." Smith adds, "The reduced excess gain from 0 to 20 mm from the sensor makes the QS18LAF250 less sensitive to lens contamination. This feature also allows for the use of an external, replaceable lens shield in particularly harsh environments."

Applications. The QS18LAF250's design uses the optical triangulation principle to accurately detect objects of varying color inside the adjustable cut-off distance, ignoring specular or shiny objects in the background. With this feature, combined with the sensor's compact housing and precise sensing beam, the QS18LAF250 provides an exceptional solution for applications where detecting minute features is critical, including the following:
Assembled part position sensing
Hole detection
Small part sensing in conveyor applications
Small feature detection and inspection
Edge detection
Plus, several features of the QS18LAF250 make it particularly easy to set up and operate:
Extended sensing range-up to 250 mm
Reduced excess gain within 20 mm of the sensor for decreased susceptibility to lens contamination
Narrow effective beam for precise sensing and small-object detection
Compact, rugged IP67-rated sealed housing
Excellent optical performance throughout sensing range
Crosstalk rejection algorithm for protection against optical disturbances from adjacent sensors
Bright LED operating status indicators visible from 360°
2 m or 9 m attached cable, and 4-pin Euro- or Pico-style pigtail QD
Mounting versatility-side mount or back mount using threaded inserts
10 to 30V dc operation
