Type 4 curtains are designed for high-risk applications where a failure could lead to severe injury, requiring redundant circuitry. Type 2 is suitable for lower-risk applications where the probability of injury is low.
Safety Light Curtains Component Intelligence
Select safety-rated light curtains based on resolution, protective height, and required performance level (PL) for your machine guarding application.
What are Safety Light Curtains components?
Safety light curtains are optoelectronic devices used to create a sensing field that triggers a machine stop when an object enters a restricted zone. Selection depends on the required safety category (ISO 13849-1), resolution for finger/hand detection, and environmental sealing.
How to Choose Safety Light Curtains Components
Selecting the correct light curtain requires balancing safety standards with physical machine constraints.
Resolution
Choose 14mm for finger detection, 30mm for hand detection, or larger for body presence sensing.
Safety Rating
Verify the required Performance Level (PL) or Safety Integrity Level (SIL) mandated by your risk assessment.
Protective Height
Ensure the active sensing area covers the entire hazardous opening plus safety margins.
Response Time
Calculate the total system response time to ensure the safety distance is sufficient to stop the machine.
Environmental Sealing
Select IP65/IP67 ratings for washdown or high-dust industrial environments.
