The SICK LFP0200-A5NMC is a Type 4 (Category 4 according to IEC 61496-1/2) safety light curtain designed for safeguarding access points on machinery with lower risk applications. It provides a cost-effective solution for protecting personnel by creating an invisible infrared detection field. When this field is interrupted, the device sends a stop signal to the machine's safety relay or controller (PLC), halting hazardous motion.
