The latest additions to the Series-28 photoelectric sensor range from Pepperl+Fuchs Visolux are the first photoelectric sensor family to be fully compatible with the AS-i Spec 2.11.

The recently introduced Series-28 is a universal sensor family for the solution of applications in many areas of the automation industry.

Since its initial launch in 2002, the product range has been expanded to include all the usual optical variations such as through-beam, reflex, direct-detect and laser versions, with time-delays and a variety of outputs and connection modes.

The new RL28xxx-AS-i units have integrated AS-i chips, allowing direct connection of up to 62 "intelligent" sensors to the AS-interface network using the latest v.2.11 specification.

Not only is it possible to monitor the output status of the RL28xxx-AS-i (beam broken or unbroken) and the "stability control" output (function reserve/alarm output) via the AS-interface, but users can also select test-input, light/dark switching and time-delay on/off.

Continuing with the excellent features from the Series-28 such as ultrabright LED indicators, low operating temperature (-40C), plastic ABS housing with scratch resistant plastic optic cover and IP67 protection class, the RL28xxx-AS-i family includes a 300m range through-beam sensor, a 12m range polarised reflection light beam switch and a selection of background suppression scanners.
