Omron E3NC-LH03 5M Smart Laser Sensor, 8 m, FDA Class I

The Omron E3NC-LH03 5M is a smart laser sensor with a separate digital amplifier, built for precision presence and position detection at range. The sensor head is a compact rectangular body, pre-wired with a 5 m cable, and uses a coaxial retro-reflective method — the laser emitter and receiver share the same optical axis, so the spot stays centered on the target regardless of distance. That spot beam, combined with the MSR (Mirror Surface Rejection) function, lets it read shiny or angled surfaces that would fool a standard photoelectric. The light source is an FDA Class I laser, meaning it is eye-safe under normal operating conditions — no special enclosure or interlocks required for most industrial installs. Maximum sensing distance is 8 m, which puts it in the medium-to-long-range bracket for a coaxial laser sensor.
