A light source and receiver are mounted in a very small housing which can be integrally mounted in the gripping arm of a robot. The source produces a narrow high intensity beam. The source and the position sensitive receiver are arranged with an acute angle between the central axis of the source and the receiver's optical axis. An electronic pulse module associated with the source and an electronic amplifier associated with the receiver are mounted in the same housing. The source is pref. a GaAlAs LED (LED) with an associated plane convex lens (L1) and aperture stops (BL1,BL2).
