Omron Automation and Safety has developed a new generation of M18 cylindrical photoelectric sensors that combine simple selection and installation with reliability, versatility, rugged construction and value for money. The E3FA plastic body and E3FB metal body sensors are suitable for applications in all industries from food and beverage production to material handling and logistics. Along with the straight-beam models, Omron also developed right-angle radial-beam plastic body E3RA and metal body E3RB models. Omron’s new photoelectric sensors offer high reliability, enhanced EMC protection, high ambient light immunity and robust waterproof housings, making them an ideal choice to meet the requirements of today’s users for non-stop operation.
The new sensors feature compact construction, allowing them to be mounted easily where space is limited. The bright red LED light source is clearly visible over long distances and provides an aid to alignment. Setting up the sensors is intuitive, and is made even easier with a large sensitivity adjustor for use with a standard size screwdriver. When the sensors are in use, instant visual confirmation of their operating status is provided by an LED indicator with a wide viewing angle.
Omron’s E3FA and E3FB photoelectric sensors include through-beam versions with ranges up to 20 m, retro-reflective versions with ranges from 0.1 to 4 m, coaxial retro-reflective versions with ranges up to 500 mm and three models of diffuse-reflective sensors with ranges of 100 mm, 300 mm and 1 m. All types are suitable for flush mounting.
While the standard models solve the vast majority of applications, the E3FA lineup also offers specialized models. These include background suppression versions for stable detection of targets with varying colors, limited-distance reflective types for reliable detection of transparent and shiny films, and types that are optimized for very stable detection of transparent bottles in dusty environments.
All sensors in the E3FA and E3RA lineup use high-power LED light sources for easy alignment and to minimize the effects of dirt, and all incorporate a pulse synchronization system to ensure maximum immunity to ambient light. They have extensive shielding for high electromagnetic noise immunity, and their robust impact-resistant bodies are fully sealed against liquid and dust ingress.
