The Omron E3AS-L80MN 5M is a background suppression photoelectric sensor from the E3AS-L series, offering a sensing range of 10mm to 80mm with NPN output. It uses a red LED (650 nm) and a teaching method for adjustment, with a 1 ms response time. The cable is 5m long, and the housing is rated IP67 and IP69K for washdown environments.
Background suppression means the sensor detects objects based on distance, not reflectivity — ideal for inconsistent targets or shiny backgrounds on a packaging line. The 10–80 mm range covers most proximity detection in conveyor or fill-level applications. The NPN output suits common PLC inputs; verify polarity before wiring. The sensor carries IP67 and IP69K protection per IEC 60529.
