Designed for precision applications, the Omron E3S-LS3NW 2M uses a Red LED (660 nm) light source and supports convergent-reflective sensing across a 10 to 60 mm sensing distance. Operating on a 12 to 24 VDC power supply with just 25 mA max. current consumption, it’s ideal for power-sensitive installations. Its NPN output and Light-ON operation mode allow for flexible system integration, while the integrated OFF-delay timer (0.1 to 1.0 s) enhances control over signal behavior in high-speed environments.
Built for durability, the E3S-LS3NW 2M includes robust protection circuits like reverse polarity, short-circuit, and mutual interference prevention. Housed in ABS and methacrylic resin, this model offers resistance to shock (500 m/s²) and vibration (10 to 55 Hz), operating reliably between −10 to 55°C. With an IP40 protection rating, it suits enclosed and clean applications, especially in electronics and automation sectors. Backed by Omron’s quality standards, this sensor ensures stable, long-lasting performance.
