OPTEX FA ET-500ND | Miniature Through-Beam Photoelectric Sensor | 500 mm, Flat ON, NPN Dark ON
The ET-500ND is a Flat ON through-beam miniature sensor detecting over 500 mm, with an NPN output fixed to Dark ON operation. At only 3.5 mm thick, the ET-500ND suits installations where height is limited, and its indicators can be seen from the back as well as the front. Like the rest of the E Series, the ET-500ND uses a red LED light source and an IP67-rated PC housing.
