The Safety Light Curtains & Safety Light Grids by Schmersal are engineered to provide non-contact protection for industrial machinery and hazardous zones. These systems use arrays of infrared light beams transmitted between an emitter and a receiver to form an invisible safety barrier.
When a person or object interrupts one or more beams, the system immediately sends a signal to the control unit, triggering a safe machine shutdown and preventing accidents.
Safety Light Curtains offer high-resolution detection (as fine as 14 mm for finger protection and 30 mm for hand detection), making them ideal for safeguarding precise danger points. In contrast, Safety Light Grids are designed for larger area protection, detecting the presence of a body or large object using fewer beams.
Schmersal systems, such as the SLC (light curtains) and SLG (light grids) series, are widely used to secure hazardous areas in robot cells, presses, palletizing systems, and automated production lines.
These devices are available with advanced functions like muting and blanking, allowing temporary bypass of the safety field during material flow without compromising overall safety.
With robust construction, high protection ratings (up to IP67/IP69K), and compliance with international safety standards, Schmersal safety light curtains and grids provide reliable performance even in harsh industrial environments.
