18mm round through-beam photoeyes detect presence when an object obstructs light traveling from emitter to receiver. Using visible red light, infrared light or laser class 1 light, these DC-powered nonmetal sensors offer detection ranges up to 50m, and are available with integral 2m pigtail cable or quick-disconnect.
