These 4-mm (smooth) and 5-mm (M5 threaded) round photoelectric sensors are available in a range of sensing distances in both diffuse and through-beam sensing configurations. These dc-powered metal sensors require minimal mounting space and are suitable for use in a variety of short- or long-distance sensing applications. Diffuse photoelectric sensors that detect object presence with reflected light from the target are available in detection distance ranges up to 120 mm. With available detection distances up to 600 mm, through-beam photoelectric sensors detect object presence when the target obstructs light traveling from the emitter to the receiver.
