Light curtains with IP67 protection

February 1, 2013
By Alison Dunn

IDEC is now offering a new line of SE4D safety light curtains, designed to offer high functionality with advanced integrated features that include no dead zone, cascading, a muting function, EDM and blanking functions, IP67 protection and the highest level of safety with Category 4, PLe, and SIL3 ratings. Conventional light curtains have a “dead zone” at both ends where there are no beam axes; however, with new IDEC SE4D Safety Light Curtains, detection can be performed along the entire area. Up to three sets of light curtains can be connected in a series to safeguard an L- or U-shape pattern without dead zones or the need for overlapping units, and since it isn’t necessary to install them outside of the detection area, the SE4D light curtain can fit into almost any system. Both PNP transistor output and NPN transistor output are available in one light curtain, so that a single light curtain supports control circuits worldwide.
