The Omron E3T-CD11 2M operates using a diffuse-reflective sensing method with a reliable sensing distance of 3 to 50 mm, optimized for detecting white objects such as 100×100 mm paper targets. It is equipped with an infrared LED (870 nm) light source and a fast 0.5 ms response time, making it ideal for rapid motion detection tasks. With a pre-wired 2-meter cable and NPN open-collector output, the sensor integrates easily into existing systems, operating on a 12 to 24 VDC power supply with low 20 mA current consumption.
Built for reliability in harsh factory conditions, the E3T-CD11 2M features IP65 protection and offers protection circuits for reverse polarity and short-circuit prevention. It can withstand vibration (10 to 55 Hz) and shock (500 m/s²), and remains stable in temperatures ranging from −25°C to 55°C. Its rugged housing—made from SUS303 stainless steel, epoxy resin, and polysulfone—ensures durability in demanding industrial environments.
