The sensors combine simple selection and installation with reliability, versatility, rugged construction and value for money. Along with the straight-beam models, there are the right-angle radial-beam plastic body E3RA and metal body E3RB models. The sensors offer high reliability, enhanced EMC protection, high ambient light immunity and robust waterproof housings, making them suitable 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 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. The 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.
