Reflectance sensors / high-performance photo sensors

Our high-performance photo sensors (reflectance sensors) are predestined for special requirements: They have the highest light intensity for maximum measuring range and/or functional reserve.

The EFS series in the classic metal cylinder case is available in 3 versions (measuring range without fibre optics):

  • EFS 1800 with measuring range up to 1,000 mm
  • EFS 2000 with measuring range up to 3,500 mm

EFS Sensors are available in a variety of configurations: infrared or red light / green light, different radiation widths, different switching outputs and connections. Please refer to the datasheets below for more details.

EFS sensors can be used as reflectance sensors when used stand alone or in combination with a suitable light guide as fibre optic reflectance sensors or fibre optic light barriers.
