Industrial safety systems frequently struggle with false alarms in harsh environments. Dust particles, ambient light, and reflective surfaces can trigger unnecessary shutdowns in conventional safety scanners.
SICK's nanoScan3 with safeHDDM® (Safe High Definition Distance Measurement) technology offers a solution specifically engineered to overcome these challenges.
The Technical Advantage of Multi-Pulse Detection
Traditional safety scanners use single-pulse time-of-flight measurement, making them vulnerable to environmental interference. The nanoScan3 takes a fundamentally different approach with safeHDDM® technology.
Rather than relying on a single measurement point per angular resolution, safeHDDM® emits multiple pulses per revolution—effectively 80,000 laser pulses within each scan of its 275° scanning range. This creates a high-density measurement field that enables advanced signal processing to distinguish between actual obstacles and environmental conditions.
These small bundles of pulses also provide small bundles of remission values, allowing the scanner to create a histogram to effectively maintain detection capability. As a result, incredibly black surfaces down to a 1.8% remission value can be reliably detected.
Performance Metrics in Challenging Environments
Ambient Light Immunity
Immune to 40 klx (per IEC 61496-3); maintains reliability under intense industrial lighting or near sunlit entrances.
Ruggedization
IP65 enclosure rating; compliant with IEC 60068-2-6 (vibration) and IEC 60068-2-27 (shock) standards.
These characteristics enable consistent 3-meter protective field performance even in conditions that would compromise conventional sensors.
Application Impact
- Machining Operations: Prevents false trips that typically occur when dust and debris interfere with safety scanners.
- AGVs/AMRs: Maintaining consistent performance across varied lighting zones without triggering false alarms that interrupt material flow.
- Space-Constrained Applications: Compact dimensions (80mm height) and light weight (0.67kg) allow integration into small mobile robots.
Engineers can monitor system health through built-in contamination measurement features and access event history for up to 150 past events.
