Model PPG is designed for perimeter guarding applications and incorporates latching safety relays (dry) with mounted manual reset button on the receiver pylon. Long scanning distances available. Type 4 \/ Category 4. Made in USA.","Perimeter Guards utilize wider beam spacing than safety light curtains protecting personnel from pinch point or point of operation hazard zones. Perimeter Guards are designed to detect when an operator or passerby penetrates the perimeter of a hazardous zone. The Perimeter Guard safety light curtain will then initiate a stop signal to the machine control.","Perimeter Guards also incorporate latching safety relays. This requires a manual reset after each penetration into the guarded zone. This is an additional safety feature to protect the intruder from an inadvertent machine actuation while the intruder is within the work area."
