The sensors can detect targets while ignoring the background that is beyond the defined cut-off range. This means that objects can be detected regardless of color and/or reflectivity, says the vendor. SA1E sensors are available with either 2m cable or M8 connectors, and with a choice of NPN output, PNP output, light ON and dark ON options. Housing dimensions are 19.5x10.8x31.5mm. The sensors are UL/c-UL listed, CE marked and IP67 rated.
