The Omron E3T-SL23 2M uses a red LED light source (650 nm) with limited reflective sensing to detect objects within a range of 5 to 30 mm. Itβs capable of identifying targets as small as 0.15 mm in diameter at 10 mm distance. Powered by a 12 to 24 VDC supply, this model delivers fast response with a 1 ms operating speed, making it ideal for high-speed sorting, positioning, and inspection processes. It comes with a PNP open-collector output and operates in Light-ON mode.
With a power consumption of only 20 mA, the sensor supports energy-efficient systems. It includes a 2-meter pre-wired cable for simple integration into control panels. Status feedback is available through orange operation and green stability indicators. The unit incorporates reverse polarity protection and short-circuit protection, ensuring robust performance even in fluctuating voltage environments.
Encased in high-strength PBT and denatured polyarylate material, the Omron E3T-SL23 2M Photoelectric Sensor is built for industrial durability. Itβs rated IP67 according to IEC 60529, withstanding water, dust, shock up to 1,000 m/sΒ², and vibration up to 2,000 Hz. Weighing just 20 g, itβs perfectly suited for use in dynamic and space-limited environments.
