Omron E3JK-R4M1 Photoelectric Sensor

The Omron E3JK-R4M1 Photoelectric Sensor is designed for accurate object detection in various industrial settings. It features a retroreflective sensing method with a 4-meter range for stable detection of objects across production and automation lines. Operating on a wide supply voltage of 12–240 VDC or 24–240 VAC, it provides flexibility for integration into diverse control systems. The sensor uses a Red LED light source and a relay output to ensure reliable switching performance in Light-ON operation mode. This model is part of the trusted Omron E3JK Series, designed specifically for consistent and durable performance in industrial automation environments.

In factory automation, the Omron E3JK-R4M1 is widely used in conveyor systems, material handling lines, and packaging machinery. It ensures precise object detection even under variable lighting and surface conditions. Thanks to its rugged plastic housing and temperature tolerance from –25°C to 55°C, it operates dependably in challenging environments. Its simple fixed sensitivity and stable response make it suitable for tasks requiring reliable presence or absence detection of components, cartons, or labels.

The Omron E3JK-R4M1 Photoelectric Sensor is a reliable retro-reflective type sensor offering a 4 m sensing distance with a red LED light source, Light-ON operation mode, and relay output for stable object detection in industrial environments. For shorter-range detection needs, the Omron E3JK-R2M1 Photoelectric Sensor provides a 2.5 m sensing distance while maintaining the same relay output and Light-ON functionality. When extended range and AC/DC versatility are required, the Omron E3JK-RR11 2M Photoelectric Sensor delivers up to 11 m detection without MSR function and supports both power options. For users preferring a DC-powered PNP output with MSR support, the Omron E3JK-RP12 2M Photoelectric Sensor ensures accurate detection up to 10 m using a red LED source. The E3JK-R4M1 remains a dependable choice for 4 m retro-reflective sensing where precision, reliability, and relay-based switching are essential for industrial automation setups.

The Omron E3JK-R4M1 Photoelectric Sensor combines durability and versatility for industrial use across India. It represents Omron’s strong presence in the automation domain, providing dependable detection with minimal maintenance requirements. This model reinforces the E3JK Series reputation for stable performance and wide voltage compatibility. For engineers and plant operators seeking consistent and long-life sensing performance, the E3JK-R4M1 stands as a trusted component in automated control systems.
