The LBGate can be used in a wide variety of applications and offers reliable protection up to a range of 30 m. The compact thru-beam light barrier system LBGate TB18 stands out with repeatable switching points and high operating reserves. The reflection light barriers LBGate R18 and LBGate R25 operate with polarised reflectors, which means only one device requires electrical connection and installation. All these principles also detect shiny and reflective objects.
