Beam Sensor
The ST4 series compact type 4 safety beam sensor offers a solution for  machine guarding applications in which the installation of safety light  curtains is cost-prohibitive or impossible due to space constraints. The  sensors provide 0.1–15 m sensing range to cover narrow spaces to wide  areas where light curtains are hard to install. The sensor head measures  14 mm x 31 mm x 28 mm.
