Light Curtains

Light curtains are critical safety devices used to protect personnel from hazardous machinery and automated systems. They operate by creating an invisible field of infrared beams between a transmitter and a receiver. When an object interrupts this sensing field, the light curtain sends a signal to stop or prevent machine operation, reducing the risk of injury while allowing efficient access to guarded areas.
These devices are commonly used in applications where frequent access to hazardous zones is required, and physical barriers are impractical. Assembly lines, robotic cells, packaging equipment, and material handling systems often rely on light curtains to provide reliable, non-contact safety protection. Their compact design and flexible mounting options make them well-suited for tight spaces and dynamic production environments.
Modern safety light curtains are engineered for durability and consistent performance, even in harsh industrial conditions. Many models are designed to tolerate dust, debris, and vibration while maintaining accurate detection. Available in configurations for finger, hand, arm, or full-body protection, light curtains help reduce downtime, improve workflow efficiency, and protect both personnel and equipment as part of a comprehensive machine safeguarding strategy.
FAQs
Q: What is a light curtain and how does it work?
A light curtain is a safety device that creates an invisible infrared light barrier. When an object interrupts the beams between the transmitter and receiver, the light curtain sends a signal to stop or inhibit machine operation to prevent injury.
Q: What are light curtains commonly used for?
Light curtains are commonly used in manufacturing, automation, robotics, packaging, and assembly lines to protect operators during tasks such as loading, unloading, or working near moving machinery.
Q: What types of light curtains are available?
Light curtains are available in different resolutions and safety levels, including finger protection, hand protection, and body protection models. They also vary by sensing range, protective height, and response time.
Q: How do light curtains differ from safety mats or safety interlocks?
Light curtains provide non-contact protection, allowing free access without stepping on mats or opening physical guards. Safety mats detect pressure, while safety interlocks monitor doors or gates. These devices are often used together for comprehensive safety systems.
Q: Do light curtains require alignment and maintenance?
Yes, proper alignment is required during installation, and routine inspection is recommended. Maintenance typically includes checking alignment, cleaning lenses, and performing functional safety tests to ensure reliable operation.
