Standard OMNI-BEAMs are modular, self-contained photoelectric sensors consisting of a sensor head, a power block, and (optionally) an output timing logic module. Standard OMNIBEAM sensor heads feature Banner's exclusive (US patent no. 4965548) D.A.T.A.™ (Display and Trouble Alert) indicator system. The D.A.T.A. system is a built-in 10-element LED array that displays sensing contrast and relative signal strength. When used along with the dedicated alarm output, it warns of impending sensing problems before a failure occurs, thereby preventing expensive down-time. The D.A.T.A. system indicator array is easily visible through a transparent, gasketed sensor head cover.
