Abstract
In an arrangement for detecting the position of two bodies moving relative to one another by a light barrier system, a device is arranged on at least one of the moving bodies such that when the bodies move relative to one another there is a change in the signal of the light barrier system that can be evaluated. At least one pair of light barrier systems is connected one with the other directly or via an electronic circuit.
