World-Beam QS18 field foreground-suppression sensors detect objects regardless of color, reflectivity, surface irregularities, or background conditions. Universal mounting makes installation quick and easy, and a simple screwdriver adjustment allows for precise setup of sensing range. In diffuse mode, the sensors detect light returned by the background, but ignores light returned by the object.
The sensors come in 15 to 40-mm and 30 to 200-mm adjustable cutoff ranges. The short-range model is suitable for detecting thinner objects closer to the background.
The sensors provide reliable detection when a fixed background is present and the object color or shape varies and objects are detected no matter how close they are to the sensor (no dead zone). A cross-talk immunity algorithm lets two sensors be used in close proximity. A visible red emitter simplifies sensor alignment.
