Banner Engineering WORLD-BEAM Q20 Sensors

The WORLD-BEAM Q20 product line is a complete product offering of high performance sensors in rectangular housings. The Q20 provides excellent optical performance in a world-wide standard sensor housing with 25.4 mm (1 inch) mounting hole spacing. The target markets are material handling, robotic assembly cells, packaging machinery for food, beverage, and pharmaceutical goods, and people detection in turn-styles and gates.

With the addition of the visible red fixed field background suppression models and increased detection range opposed mode sensors, Banner has expanded the number of applications the Q20 series can solve. The high performance optical design of the fixed field Q20 series is evident in the small emitter beam and well focused optics which provide increased sensing range, out to 150 mm (6 inches) and greater immunity to objects beyond the fixed detection range. Combined with electronic immunity to fluorescent light sources, the Q20 fixed field sensors will result in more reliable and more stable detection in all applications.

As a part of Banner’s continuous improvement program, the opposed mode sensor lenses were improved resulting in additional sensing range of 2 m in the visible red models, and an additional 5 m range in the infra-red models. Sensor apertures are available to shape the effective sensing beam to the part being detected, and polarized filter pairs allow multiple opposed mode sensor pairs to be used in close proximity without cross talk.
