What is fixed blanking and floating blanking?
Fixed Blanking is when a fixed set of adjacent light beams are rendered permanently inactive for the purpose of allowing product or part of the process to enter the sensing area without deactivating the light curtain safety outputs. An example would be the blanking of a small segment of the light curtain to allow finished parts to eject from a machining operation through this specific opening in the protected field. Floating blanking is when a set number (one or more) of adjacent beams is allowed to ignore the presence of an object within their portion of the protection field. However, unlike fixed blanking (where the specific set of inactive beams are fixed), floating blanking allows the set number of adjacent beams to float within protected field thus allowing the object to be ignored to move within the protected field without deactivating the light curtain safety outputs. As long as no more than the selected number of adjacent beams is interrupted, the system remains operational and
