Safety light grids with muting function are advanced photoelectric safety devices used in industrial automation to protect workers from hazardous machinery. These systems are typically offered by leading safety equipment manufacturers from countries like Germany (e.g., SICK AG, Leuze electronic) and the USA (e.g., Banner Engineering, Rockwell Automation). They serve industries such as manufacturing, packaging, and automotive, providing intrusion detection and muting capabilities during material handling. Key products include Type 4 safety light curtains (e.g., SICK deTec4 Core) with programmable muting sensors for palletizing applications, compliant with ISO 13849-1 safety standards. These grids feature IP65 protection and integrate with PLCs for smart factory environments.
