When an object (typically a hand or body part) breaks the beam pattern, the light curtain signals the safety circuit to stop the machine. This class of device is used for point-of-operation guarding, access guarding, and perimeter protection on presses, assembly lines, and automated cells.
Deployment context
As a safety light curtain, the F3SJ-E0705N25 mounts to guarding frames or machine stands using the provided brackets and alignment hardware. The emitter and receiver pair must be aligned within the specified range and connected to a safety-rated controller or relay that matches the output type. The bulk packaging means the unit ships as a single assembled pair, ready for installation.
