SICK microScan3 vs Banner SC26: Industrial Safety Laser Scanners & Guarding

Automated Guided Vehicles (AGVs), Autonomous Mobile Robots (AMRs), and hazardous robotic workcells require fail-safe optical area protection. The SICK microScan3 series (utilizing patented safeHDDM scanning technology) and Banner Safety Controller (SC26-2 / XS26-2) represent leading standards for functional safety compliance (ISO 13849-1 Category 4 / PLe, IEC 62061 SIL 3).

2. Dynamic Field Switching on Mobile Robots (AGV/AMR)

For AGVs navigating warehouse aisles:

1. Incremental Encoder Inputs: Feed dual optical encoder signals (A/B phase) into the safety scanner to compute velocity and turning angles in real-time.
2. Dynamic Protective Fields: Automatically expand the protective safety zone at high forward velocity (>1.5 m/s) and contract during tight turning maneuvers to avoid false e-stop trips.
