Frequently Asked Questions (FAQ)
What is the difference between Type 2 and Type 4 safety light curtains?
Type 2 safety light curtains are designed for lower-risk applications where the probability of injury is relatively low and additional risk reduction measures may be present. Type 4 safety light curtains, on the other hand, are intended for high-risk machinery and hazardous environments, offering higher fault tolerance and stricter safety performance. The choice depends on risk assessment results and applicable safety standards.
How do I choose the right safety light curtain manufacturer for my machine?
Selecting a safety light curtain manufacturer should be based on application requirements rather than brand popularity alone. Key factors include required safety level, detection resolution, protective height, installation distance, integration with control systems, and budget constraints. Manufacturers like DADISICK are often selected for application-driven projects where flexibility and cost-performance balance are important.
Are expensive safety light curtains always safer or better?
Not necessarily. Higher-priced safety light curtains often provide advanced diagnostics, premium materials, or brand-related service advantages. However, for many standard applications, mid-range solutions that comply with international safety standards can deliver reliable protection without unnecessary cost. Proper specification matching is more important than price alone.
Can safety light curtains be used on different types of machines?
Yes. Safety light curtains are widely used on press machines, laser cutting equipment, packaging machinery, automated assembly lines, robotic cells, and material handling systems. The key is selecting the correct detection resolution, protective height, and mounting distance based on the specific machine hazard.
When is a wide scanning range safety light curtain recommended?
Wide scanning range safety light curtains are recommended for applications with large openings or long protection distances, such as conveyors, palletizers, or large automated equipment. In these cases, using a wide scanning range solution—such as DADISICK wide scanning range safety light curtains—can reduce the need for multiple units while maintaining stable detection.
Do safety light curtains require regular maintenance?
Safety light curtains generally require minimal maintenance, but periodic inspection is recommended. This includes checking alignment, cleaning optical surfaces, verifying wiring integrity, and performing functional tests according to the machine safety plan. Proper installation and stable mounting significantly reduce long-term maintenance needs.
Conclusion
The global safety light curtain market includes both long-established brands and specialized manufacturers. Understanding each supplier's strengths and application focus allows engineers and decision-makers to select solutions that meet real-world requirements.
