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.
Our Bulletin 440L Guardshield PAC Type 4 safety light curtains are applied in applications where a formal risk assessment has determined that the hazard poses a moderate to high risk of operator injury.
Our Bulletin 440L Area Access Control Single Beam sensors provide whole-body access detection for hazardous areas. The single beam is a 24V DC through-beam opto-electronic safety switch.
