2. For Your Safety
2.1 Use for Intended Purpose
The product is based on the following functional principle:
Reflex Sensors with Background Suppression
Reflex sensors with background suppression analyze the light reflected from objects. As these sensors work
according to the principle of angular measurement, the color, shape and surface characteristics of the object
have almost no influence on the detection range. Even dark objects can be reliably detected against a bright
background. The output is switched as soon as an object passes the selected range.
This product can be used in the following industry sectors:
• Special machinery manufacturing
• Heavy machinery manufacturing
• Logistics
• Automotive industry
• Food industry
• Packaging industry
• Pharmaceuticals industry
• Plastics industry
• Woodworking industry
• Consumer goods industry
• Paper industry
• Electronics industry
• Glass industry
• Steel industry
• Aviation industry
• Chemicals industry
• Alternative energy
• Raw materials extraction
2.2 Use for Other than the Intended Purpose
• Not a safety component in accordance with 2006/42/EC (Machinery Directive)
• The product is not suitable for use in potentially explosive atmospheres.
• The product may only be used with accessories supplied or approved by wenglor, or combined with
approved products. A list of approved accessories and combination products can be accessed at
