CX series through-beam photoeyes detect presence when an object obstructs light traveling from emitter to receiver. Using infrared light, these DC-powered rectangular sensors offer adjustable detection ranges up to 6m, and are available with integral 2m pigtail cable or quick-disconnect.
There are many different styles of photoelectric sensors, but really only four basic technologies: through-beam, reflective, diffuse, and background suppression. The categories of these types of DC photoelectric sensors available from AutomationDirect are:
