What is the purpose of a presence sensing device?

The primary purpose of a presence sensing device is to detect the presence of an object or person within a specific area or near a machine. These devices are essential for ensuring safety in industrial environments, as they can trigger safety mechanisms when someone or something enters a hazardous zone. For example, in the context of machine guarding, presence sensing devices such as light curtains, pressure mats, or photoelectric sensors can halt operations or activate safety measures, preventing accidents and injuries by ensuring that no individual or object is in the machine's danger zone while it is in operation. This capability is crucial in the design of safe workspaces and machinery, particularly where automated processes occur.
