An assembly for automatically detecting contactlessly elongate objects (W). The assembly comprises an inductive measuring system (E) and a first optical measuring system (D) for the object (W) within a housing (). The inductive measuring system (E) is an eddy current sensor for determining an electromagnetic characteristic of the object (W) and has half coils (E, E) which wind around the object (W) and forms an inductive cylindrical measurement volume (Ev). The half coils (E, E), together with a capacitor (E), form a parallel oscillating circuit (E), which is connected to an electronic evaluating circuit (E). The first optical measuring system (D) determines the outside diameter (Wdo) of the object (W) and an optical disk-shaped measurement volume (DCPv) is formed between the two half coils (E, E). Optionally, the assembly, by a second optical measuring system (C), determines the color and the position by a third virtual measuring system (P).

Combination sensor

An arrangement for automatically contactlessly detecting elongate objects (W), such as cables, wires or profiles, has a quasi-coaxially arranged group of a first optical measuring system (D) for determining the external diameter and a second optical measuring system (C) for determining the color using a different measurement principle. The functional and local separation of the two measuring systems (C, D) is achieved by using different wavelength ranges and by a long-pass filter (C). A third, virtual measuring system (P) may be provided for the purpose of determining the cable location and is used to weight measured values of the color measurement and measured values of an optional eddy current sensor. The optical measuring systems (D, C, P) for determining the diameter, the color and the position have a common optical disc-shaped measuring volume (DCPv) which is preferably arranged centrally in the guide device () for the elongate object (W).
