A coupling system allows interconnection of multiple light curtains segments but prevents interconnecting dissimilar segment types. A first connector half mounts to a segment while a second connector half mounts to another segment, such that mating the two halves interconnects the two segments. The two mating sections of the connector or coupling system may be formed as matched mating blocks that are mounted in different orientations, depending upon whether they are attached to transmitter or receiver type light curtain segments. One or both mating sections may rotatably mount to its respective segment, thereby providing an articulated connection between the joined segments. In other implementation, one mating section may be formed as a reversible coupler, with the other mating section formed as a mating receptacle that may be conveniently keyed to accept only a particular orientation of coupler.
