Designed for extended-range object detection, the Omron E3NC-LH03 5M Photoelectric Sensor utilizes a coaxial retroreflective sensing method with MSR (Mirror Surface Rejection) to maintain stability even when detecting shiny, angled, or background-reflective surfaces. Powered by a red semiconductor laser diode (660 nm), this unit offers multi-mode sensing capabilities, with a maximum sensing distance of 8 meters in giga-power mode and other selectable ranges down to 2 meters in super-high-speed mode.
Installation is simplified with a durable pre-wired 5-meter connector cable, offering flexibility for larger setups or remote sensor placement. The device features built-in OUT (orange) and STABILITY (green) indicators for easy status monitoring. Built to withstand harsh conditions, the sensor operates reliably in temperatures from β10Β°C to 55Β°C and in bright ambient lighting up to 20,000 lx. With its rugged IP67-rated housing made of PBT, PMMA, and PVC, the sensor is dustproof, waterproof, and resistant to vibration and shock β up to 500 m/sΒ².
With strong insulation resistance of 20 MΞ© at 500 VDC and a dielectric strength of 1,000 VAC, the E3NC-LH03 5M offers dependable electrical safety for long-term industrial deployment. Weighing around 180 grams, this robust unit is ideal for high-speed packaging, robotic vision, and machine control systems.
