EOS4 Light Curtain


The EOS4 Light Curtain provides a protection rating of IP65 and IP67 all in a compact housing that uses a cross-section of only 1.1 x 1.2 in. (28 x 30 mm).


The EOS4 is installed with M12 connectors, has two safety PNP static outputs, and features mechanical and electrical robustness. The line includes models with integrated safety functions including self-monitoring of static outputs, control of external contactors, and an automatic/manual selectable restart function. Master/Slave models are also available for cascade connection of two or three units. There are even models designed specifically for industries and applications where high Vibration Resistance is important such as the textile industry.


The EOS4 is also available in an Explosion Proof ATEX model as well as with a watertight, food graded, IP69K certified enclosure for harsh environments or food processing applications where wash-downs are common.
