<p>The light grid has modules (10) including a transducer interface (18) at opposite ends of housing (12) of the transducer, where the transducer interfaces are located in mating surfaces (16) of the housing such that the mating surfaces of modules are to be coupled to one another at their surfaces. The housings of the modules are elongated and contain a light emitter and light receptors, which are arranged in a row parallel to the longitudinal axis of the housing. The mating surfaces (16) are located at an angle with respect to the longitudinal axis of the housing (12).</p> |
