Omron E3NC-LH03 2M Photoelectric Sensor
Omron E3NC-LH03 2M is a coaxial retro-reflective smart laser sensor head with an MSR function for sensing targets across a distance of up to 8 m. Its visible 660 nm semiconductor laser diode creates the optical path, while the coaxial arrangement aligns transmitted and returned light along the same sensing axis. A 2 m pre-wired connector cable provides the connection to compatible E3NC equipment. Orange OUT and green STABILITY indicators provide visual operating information during setup, and the sensor supports ambient light levels up to 20,000 lx under sunlight. Within the E3NC Series, the E3NC-LH03 2M provides the 2 m cable version. Related coaxial retro-reflective laser sensors are available across Omron Sensor Products.

The Omron E3NC-LH03 2M Photoelectric Sensor uses coaxial retro-reflective laser sensing with an MSR function across a maximum distance of 8 m. A visible 660 nm semiconductor laser diode creates the optical path, while the coaxial arrangement keeps transmitted and returned light aligned along the sensing axis. A 2 m pre-wired connector cable provides connection to compatible E3NC equipment. Orange OUT and green STABILITY indicators provide visual operating information. Ambient-light resistance is specified at 10,000 lx under incandescent light and 20,000 lx under sunlight. Operating temperature extends from -10 to 55°C, while storage is specified from -25 to 70°C without icing or condensation. Humidity is listed from 35% to 85%, and insulation resistance is 20 MΩ minimum at 500 VDC.
For an Omron coaxial retro reflective laser sensor requiring an 8 m sensing range and MSR function, the relevant model is the E3NC-LH03. Dielectric strength is specified at 1,000 VAC for one minute, while vibration and shock resistance are also listed in the supplied specification. The sensor head uses PBT, PMMA, and PVC among its stated materials. Its specification also matches searches for an Omron 8 m laser sensor and Omron MSR laser sensor. The 2 m cable version is suitable where associated E3NC equipment is positioned close to the sensing point. For the same coaxial retro-reflective sensing specification with additional cable length, see E3NC-LH03 5M.
