Perimeter Guarding
Product
Overview
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.
