The Siemens 3RG7834-6DE00 is a SIMATIC FS660I Type 3 laser scanner — a safety-rated area guarding device, not a simple presence sensor. It projects a horizontal protection field up to 4 m, with 8 individually configurable protection fields (set to 30, 40, 50, 70, or 150 mm field resolution depending on the zone). The vertical mount orientation means the scan plane is perpendicular to the floor, suited for guarding access zones where a horizontal plane would miss hazards at different heights.

Protection field configuration and deployment
The 8 protection fields define multiple warning and safety zones within the 4 m range — a 150 mm resolution field for coarse area detection and a 30 mm resolution field for hand/finger detection near the hazard. Because this is a Type 3 scanner per IEC 61496, it is rated for applications up to SIL 2 / PL d, suitable for guarding robot cells, AGV paths, and machine access areas. The vertical orientation is less common than horizontal ceiling mount — it suits narrow doorways or vertical access gates where a horizontal scanner would have an obstructed field.
