QS18AFF200 Foreground Suppression Sensor Installation Guide

This document provides installation, configuration, and wiring instructions for the Banner Engineering QS18AFF200 series mechanically adjustable foreground suppression sensors, which detect objects by sensing changes in light reflected from a fixed background. It covers models with NPN, PNP, and bipolar outputs, cutoff distance adjustment via a multi-turn screw, and guidelines for reliable detection with varying object colors and shapes.
