It detects up to 7 m with a 500 µs response — fast enough for package tracking and conveyor gap detection. Rated IP67, so it stands up to washdown environments. How many you need? I can source these. ## Drop-in with E3SAT81 The E3SAT81 carries the same specs — PNP, 7 m, 500 µs, pre-wired, IP67, red LED. It's a direct functional substitute: same mounting hole pattern, same three-wire PNP wiring colors (brown, blue, black). If your BOM listed E3SAT81, the E3SAT31 fits without a panel change. We can quote either code.","metaTitle":"Omron E3SAT31 PNP Photoelectric Sensor, 7m, 500µs, IP67","metaDescription":"Omron E3SAT31 E3S-A photoelectric proximity sensor, PNP output, 7m sensing distance, 500 µs response, IP67, pre-wired.
