Types of Light Curtains
Point of Operation Guarding (POC) Light Curtains
The pinch point, or zone of hazardous operation, is another name for the point of activity. Mechanical and hydraulic power presses, molding presses, stamping, shaping, riveting, eyelet, and automated assembly machinery all use this type of protection. Light curtains are commonly utilized in these applications to protect fingers and hands. These light curtains are usually placed right next to the machine, where the worker will interact with it.
Perimeter Access Control (PAC) Light Curtains
Light curtains are typically used in these applications to detect the presence of personnel and alert the machine controller, allowing dangerous conditions to be avoided while the personnel is present within the protected area. To prevent the automatic resumption of machine motion, the light curtain reset switch must be situated outside and visible from the protected area. Arm and body detection is the most common reason for using light curtains for perimeter security.
