The distance sensor equipped with a red light LED is optionally available with one or two measuring ranges (20 to 80 mm, 30 to 200 mm). The distance value measured is emitted in the form of a linear voltage value (1 to 10 V) via the integrated analogue output. The FT 25 RA also has a digital signal output, and the measuring ranges for both outputs can be set independently of each other. An inversion of the analogue characteristic curve is also possible.
The FT 25 RA reliably and accurately measures the distance to target objects of any colour and surface finish. Even highly-reflective surfaces have practically no impact on the sensor’s excellent repeatability, which is ± 0.4 mm at a distance of 80 mm from the target object. Sensors can be easily replaced with virtually no need for calibration due to their high linearity.
Thanks to its high measuring accuracy with a huge variety of objects, the FT 25 RA is ideal for a wide range of industrial applications – for example for tension and dancer control in automatic winding machines in the printing and packing industry, for distance measurement on robotic gripper arms and determining the position of parts, for stack height control and double layer detection in the paper and wood industry, as well as for level measurement of opaque liquids.
The UL certified FT 25 RA is particularly suited to use in confined locations thanks to its compact dimensions, and can be easily and flexibly installed with the aid of a dovetail mount.
