The Omron E3JM-DS70M4-G Photoelectric Sensor, part of the reliable Omron E3JM Series, ensures stable diffuse-reflective detection for industrial automation systems. With a 700 mm sensing distance, infrared LED (940 nm) light source, and wide power range of 12–240 VDC or 24–240 VAC, it provides consistent detection across metallic, plastic, and reflective surfaces. The SPDT relay output (3 A at 250 VAC) allows direct load switching, while the Light-ON/Dark-ON selectable operation enhances adaptability. Featuring a quick 30 ms response time and IP66-rated enclosure, the E3JM-DS70M4-G offers dependable mid-range sensing and long-term stability in demanding automation setups.
In packaging lines, material-handling conveyors, and assembly applications, the Omron E3JM-DS70M4-G Photoelectric Sensor ensures precise detection for carton positioning, part counting, and label presence. Its diffuse-reflective method simplifies system design by eliminating the need for external reflectors, minimizing installation time and cost. The adjustable ON-delay, OFF-delay, and one-shot timer functions allow fine-tuning for synchronized operations. Operating between −25°C to 55°C, the sensor withstands vibrations up to 55 Hz, maintaining accuracy and consistency even in high-speed or high-vibration production lines, making it ideal for OEM and factory automation environments.
Engineered by Omron Corporation, a globally recognized leader in automation technology, the E3JM-DS70M4-G is manufactured under ISO-certified standards ensuring top-quality reliability. The rugged ABS and polycarbonate housing resists harsh conditions, while its reverse polarity and short-circuit protection guarantee safe, stable operation. Maintenance teams and engineers across India value Omron sensors for their durability, easy installation through terminal blocks, and support backed by Omron Automation India’s extensive service network. The combination of global reliability and local technical assistance ensures reduced downtime and improved system efficiency.
The Omron E3JM Series also includes other variants with the same sensing performance and housing design but different conduit thread types. The Omron E3JM-DS70M4 model features a PF1/2 conduit socket thread suitable for standard Indian installations, while the Omron E3JM-DS70M4-US comes with a 1/2-14NPT thread for global compatibility. Both offer the same 700 mm sensing range, relay output, and IP66 protection, providing easy interchangeability and consistent performance across automation systems.
The Omron E3JM-DS70M4-G Photoelectric Sensor combines versatility, reliability, and precision for industrial automation applications. Its wide voltage range, robust housing, and integrated timing options make it an excellent choice for packaging, manufacturing, and logistics operations.
