440L GUARDSHIELD SAFETY LIGHT CURTAIN RES 30MM PT HT 1280MM 64 BEAMS INTEGRATED LASER ALIGNMENT

Elevate safety and efficiency on your production line with the Allen-Bradley 440L GuardShield™ PAC Type 4 safety light curtain range—a smart, durable solution for perimeter and access protection in medium- to high-risk industrial environments. These optically synchronized transmitter-receiver systems create a secure infrared barrier up to 16 m wide, triggering immediate machine shutdown via redundant OSSD safety outputs (24 V DC, 500 mA) upon beam interruption. Designed for flexibility and ease of use, the 440L range offers DIP switch-configurable functions including beam coding to prevent optical interference, start/restart interlock for manual reset control, external device monitoring (EDM), teachable blanking zones, and remote-teach or cascading options—all compliant with IEC 61496-1 Type 4 standards, EN ISO 13849 safety categories, and UL listings. Engineered for reliable performance, the IP65-rated housing withstands harsh factory conditions, while quick-connect M12 wiring ensures fast installation. Built-in laser alignment (available models) simplifies setup, and response times as fast as 20 ms guarantee rapid hazard detection. Whether you need standalone protection, cascading multi-beam configurations, or networked connectivity via ArmorBlock Guard I/O, the 440L GuardShield delivers premium safety performance, compliance, and operational efficiency—all with the trusted quality of Allen-Bradley.
