E3FA/E3RA & E3FB/E3RB Photoelectric Sensors

Omron Industrial Automation E3FA/E3RA and E3FB/E3RB Photoelectric Sensors are a family of high-performance sensors in a universal M18 cylindrical plastic housing designed for standard or special applications. This rugged housing is designed to withstand high-pressure and high-temperature washdown (IP67, IP69K ingress protection). Omron Industrial Automation E3FA/E3RA and E3FB/E3RB feature bright LED indicators that provide status visibility from almost any angle. A high-power red LED provides easy sensor alignment and dependable outputs in dusty environments. These photoelectric sensors also include high electromagnetic compatibility (EMC) protection and ambient light immunity for detection stability in environments with excess noise or background light.
