Background or foreground

The Omron E3Z-LS is claimed to be the only diffuse photoelectric sensor in the world that offers both foreground and background suppression.

The new Omron E3Z-LS is claimed to be the only diffuse photoelectric sensor in the world that offers both foreground and background suppression.

The background suppression (BGS) function handles applications where the background can cause false detections. Foreground suppression (FGS) is used with targets that present shiny or irregular surfaces.

With BGS and FGS in one package, users do not have to buy multiple sensors to handle the same application. Also, the E3Z-LS sensor’s low black/white error of 10% ensures reliable detection regardless of the target’s colour or glossiness.

The E3Z-LS has a visible beam, which ensures easy alignment. In addition, the E3Z’s unique algorithm also minimises the effect of external light interference from fluorescent lighting.

The E3Z-LS is housed in an IP67 rated enclosure and features a choice of NPN or PNP output models. The E3Z-LS is suitable for packaging and material handling applications. It is especially useful for packaging applications that have a highly reflective background or that have targets that have shiny or irregular surfaces.

The E3Z-LS programmable diffuse sensor is available from stock starting at $135.
