Point of Operation Control (POC) safety light curtains are designed for finger, hand, and arm detection. These light curtains are placed close to the hazard, at the point of operation where personnel may frequently interact with the machine.
Perimeter Access Control (PAC) and Area Access Control (AAC) safety light curtains provide full-body access detection. These light curtains are designed to create a safety perimeter around a machine that does not require frequent interaction between personnel and the hazard during regular operation. PAC and AAC safety light curtains are typically used as opto-electronic fences to detect personnel or large objects when they pass through the sensing field.
