Photoelectrical sensors of the Gxx series are all-purpose switches used in machine systems and equipment for nocontact surveillance of motion of elements. They are based on the photoelectric principle of operation – inside thesensor there is a photo signal emitter and receiver of the returned signal. There are three types of sensors: diffusesensors, reflector sensors and emitter-receiver sensors. These types of sensors differ in the way of returning thesignal. They allow for gearing distance adjustment. They are developed on the base of PNP and NPN transition.They have small dimensions and feature a metal cylindrical shell resistant to vibrations and a plastic lid which is oiland water resistant.
