Allen Bradley GuardMaster 442L-RA41530CBCD_A Light Curtain – 1500 mm Safety Sensor
🔒 Product Overview
The Allen Bradley GuardMaster 442L-RA41530CBCD_A is a light curtain designed to provide reliable safety protection for personnel around automated machinery. With an active sensing height of 1500 mm, this model offers a broad protective field ideal for large machine guarding applications. It uses an array of infrared light beams to create an invisible safety barrier. When any beam is interrupted, the device immediately signals the control system to stop hazardous motion. The 442L series is known for its rugged build, high immunity to interference, and fast response times. It is widely used in industrial automation settings to meet strict safety standards and reduce workplace accidents.

⚙️ Functional Description
The GuardMaster 442L-RA41530CBCD_A light curtain functions as a critical safety device that guards access points around dangerous machinery. It is often installed around robotic cells, presses, conveyor belts, and packaging lines. The unit emits multiple infrared beams between a transmitter and receiver. When all beams are clear, the system allows the machine to operate normally. If any beam is broken, the control relay or safety PLC receives an immediate stop command. This prevents injuries caused by accidental entry into hazardous zones.
The device supports easy alignment thanks to built-in LED indicators that help during installation and maintenance. Its durable housing protects it from harsh industrial environments such as dust, moisture, and vibrations. The light curtain meets the highest safety categories, allowing it to be used in applications requiring SIL 3 or Category 4 safety ratings. This model also supports muting functions and blanking zones, enabling flexible guarding without compromising safety. It is designed to work seamlessly with Allen Bradley’s GuardLogix safety controllers and other Allen Bradley automation systems.
