ALLEN‑BRADLEY GUARDMASTER 442L‑RA41530CBCD_A LIGHT CURTAIN – 1500 MM, 75 BEAMS, FEB 2021
The Allen‑Bradley GuardMaster 442L‑RA41530CBCD_A is a safety light curtain made for machine guarding and perimeter protection. It has a sensing height of 1500 mm and 75 detection beams. 📏 Each beam has a small 14 mm pitch. The unit works on 24 V DC and uses PNP outputs for easy wiring. ⚙️ It meets IEC 61496‑1 Type 2 safety standards. The casing is aluminum with a clear, robust front cover made of polycarbonate. This cover protects the optical elements from dust and spills. The light curtain uses modulated infrared beams so it resists interference from ambient light. It also has automatic beam alignment and fault diagnostics. Each end cap has status LEDs. These LEDs show power, beam status, and fault detection.
This light curtain uses quick‑disconnect M12 connectors for power and output lines. 🔌 The connectors use 5‑pin for power and 8‑pin for dual-channel safety outputs. It includes built‑in blanking for small parts handling. Blanking lets a tool or part move through without stopping the machine. The blanking mode can block up to 16 beams. It has automatic restart inhibitor and muting input. These functions let materials pass safely when external devices signal the curtain. The unit has IP 65/67 rating so it works in washdown areas. It can work in –25 °C to +55 °C. The aluminum housing draws heat away so the system stays cool under long use.
Many manufacturers in automotive, food, and packaging industries use this model. 🏭 It guards robot cells, assembly stations, and conveyor lines. Recent news shows that factory safety automation is growing in Asia and Europe. Companies now use more smart safety devices to meet ISO 13849 performance levels. They link light curtains to safety PLCs and IIoT platforms. This trend helps reduce downtime and cut risk of accidents. Some firms report 30 % fewer safety incidents after installing modern light curtains. The GuardMaster series remains popular because it blends proven reliability with new features for Industry 4.0 integration.
