LT Series 3D Safety Protection Sensor – Spatial Safety Protection for Automotive Final Assembly
AI-Powered Spatial Protection with Effortless Deployment
LT series
Scheme consultation
Project Background Introduction
In an automotive final assembly workshop, vehicle bodies are transferred via conveyor lines after being positioned by elevators. The center aisle at elevator entrances serves as vehicle transport paths, but personnel may enter restricted elevator areas, causing safety hazards. WONSOR's LT Series – China's first 3D safety sensor – is TÜV-certified with PLd-rated safety circuits. It effectively addresses gaps in traditional guarding for human-robot collaboration scenarios, ensuring manufacturing safety while significantly boosting production efficiency.

Detection Requirements
  • Instant alarm upon personnel entering elevator zones; conveyor lines and elevators halt immediately.
  • System cannot be reset while personnel remain in elevator areas.
  • Uninterrupted detection during vehicle passage.
