The SICK DGS66-CTM01024 is a Type 4 safety light curtain designed for industrial machine guarding and personnel protection. It creates an invisible infrared beam barrier to detect intrusions into hazardous areas (e.g., presses, robots, automated machinery). When the beam is interrupted, it triggers an immediate safety stop (via OSSD outputs) to prevent accidents. With a robust metal housing, high noise immunity, and flexible configuration, it meets stringent safety standards (IEC 61496-1/2) and is ideal for harsh manufacturing environments.
