Pepperl+Fuchs reflective sensors are optoelectronic devices used to detect the presence or absence of an object by measuring the reflection of an emitted light beam. These sensors find widespread applications
in various industries, including automation, packaging, and material handling. They are available in a wide range of designs to suit different sensing distances, object colors, and environmental conditions.
Key Features and Specifications
Sensing Distance: Varies depending on the model, from a few millimeters to several meters.
Detection Mode: Retro-reflective (requires a reflector), diffuse reflective (detects objects directly), or background suppression.
Light Source:Typically uses infrared or visible light.
Output:Normally provides a switching output (e.g., PNP, NPN) or an analog output (e.g., 4-20 mA).
Housing: Available in various housing materials and protection ratings (IP) to suit different environments.
Additional Features: Some models may offer features like adjustable sensitivity, background suppression, and diagnostic functions.
