E3FA and E3FB cylindrical photoelectric sensors are compact, allowing them to be mounted where space is limited. Setup is intuitive: Sensitivity is adjusted with a standard-size screwdriver.
The E3FA is a plastic body sensor, while the E3FB has a metal body. Both models include through-beam versions with ranges to 20 m, retroreflective versions with ranges from 0.1 to 4, coaxial retroreflective versions with ranges to 500 mm, and three models of diffuse-reflective sensors with ranges of 100 mm, 300 mm, and 1 m. All sensors in the line use high-power LED light sources for easy alignment and to minimize the effects of dirt, and all use a pulse-synchronization system to ensure maximum immunity to ambient light. They have extensive shielding for high electromagnetic noise immunity, and their impact-resistant bodies are fully sealed against liquid and dust ingress.
