ABSTRACT:
A light waveguide sensor for small pulling or pressing forces comprises a primarily coated light waveguide, a coil wound on the light waveguide and composed of an element having a diameter which is smaller than a diameter of the primarily coated light waveguide, a casing surrounding the primarily coated light waveguide and the coil and composed of a fiber reinforced synthetic plastic material with longitudinally extending, pulling resistant fibers embedded in a synthetic plastic matrix, the coil being composed of a plurality of coils arranged in cross-lay relative to one another on the light waveguide and each having a pitch length greater than 2.2 times the diameter of the primarily coated light waveguide.
