For customers with very large machines that occasionally need operator access, it can become very costly and cumbersome to protect the area around the machine from intrusion with traditional hard guarding. The PA4600 perimeter access safety light curtain provides a long-range, multi-beam presence sensing device for guarding robot centers and large machines. More economical than traditional hard guarding, the PA4600 allows for easy access while still maintaining operator safety.
