It switches NPN, light-on, on a 12-24V DC supply, and terminates in a 2 m bare-wire cable. The rectangular PBT body carries an IP67 seal, rated from -13 to 131 °F, so it handles washdown zones and outdoor conveyor lines without a secondary enclosure. ## Response time and switching 1 msec response time suits high-speed counting on a bottling line or part-present detection on a fast-moving belt. Light-on mode only — if your application requires dark-on, the E3T series offers complementary variants; verify the switching logic before wiring.","metaTitle":"Omron E3T-ST11 Photoelectric Sensor, Through-Beam, NPN, 1 m, IP67","metaDescription":"Omron E3T-ST11 through-beam photoelectric sensor set (transmitter + receiver).
