Procurement Notes

Verify the specific emitter or receiver configuration required for the installation, as this part number corresponds to a single unit within a paired system. Confirm that the control logic supports the required safety category and performance level. Ensure compatibility with existing safety controllers regarding interface signals and wiring standards before procurement.

Selection Notes

Select this model when a compact safety solution with a 300 mm height is required for narrow access points. The 40 mm resolution is suitable for preventing hand intrusion while allowing necessary material passage. Consider the operating distance and environmental conditions to ensure the laser source remains effective against ambient light interference.

Part Context

This component belongs to SICK's portfolio of safety light curtains, which are engineered for industrial automation. These devices function by creating an invisible protective field using infrared or laser beams. When interrupted, they trigger immediate machine stop commands to prevent injury, serving as critical components in modern safety architecture.
