Omron E3S-LS3NW 2M Photoelectric Sensor
Omron E3S-LS3NW 2M is an NPN convergent-reflective photoelectric sensor for short-distance object sensing across a range of 10 to 60 mm. A 660 nm red LED provides the optical source, allowing targets inside the defined sensing area to control the NPN switching output. The sensor operates from 12 to 24 VDC and includes a 2 m pre-wired cable for electrical integration. Light-ON operation is specified, while the adjustable OFF-delay timer covers 0.1 to 1.0 s for applications requiring delayed reset. Current consumption is 25 mA maximum and response time is 1 ms. Within the E3S Series, the E3S-LS3NW 2M provides the wider convergent sensing zone. Explore short-range reflective sensors across Omron Industrial Sensors.

The Omron E3S-LS3NW 2M Photoelectric Sensor uses convergent-reflective sensing across a defined working range of 10 to 60 mm. A 660 nm red LED provides the optical source, while returned light from a target positioned within this zone controls the NPN output state. The sensor operates from 12 to 24 VDC and includes a 2 m pre-wired cable for machine connection. Current consumption is specified at 25 mA maximum, while the load supply voltage reaches 24 VDC and load current up to 100 mA. Light-ON operation is specified. Operate or reset time is 1 ms maximum, while an adjustable OFF-delay timer covering 0.1 to 1.0 s supports applications where the output must remain active briefly after the target condition changes.
For an Omron convergent reflective sensor requiring a wider 10 to 60 mm short-range sensing zone, the relevant model is the E3S-LS3NW. Incandescent-light resistance is specified at 5,000 lx maximum. Operating temperature extends from -10 to 55°C, while storage ranges from -25 to 70°C. Power-supply reverse polarity, output short-circuit, and mutual-interference prevention are included. ABS and methacrylic resin are among the listed materials. Its specification also suits searches for an Omron 60 mm NPN sensor and Omron convergent photoelectric sensor. For an E3S version using a narrower 20 to 35 mm working range, see E3S-LS3N 2M.
