The edge detectors of RED series primarily are designed for detecting and counting edges. These may be e.g. newspapers, single sheets, cardboard boxes, sheet metals, wires, lamellas, welds, rotor blades, etc.In its optimum operating range (e.g. 110 mm when RED-110-…) sheet edges starting from 0.1 mm are reliably detected. The sensor is characterised by a high scanning frequency and by its ability to automatically adjust itself to differently bright and dark, as well as slow and fast objects; with a minimally set output pulse length (adjustable via software) it reaches a switching frequency of 10 kHz. Furthermore the sensor can be used for almost all conceivable applications by selecting optimised software algorithms.
