SIMATIC FS620I Type 3 laser scanner, 4 m horizontal field
The Siemens 3RG7834-6DD00 is a SIMATIC FS620I laser scanner classified as Type 3 per IEC 61496, configured for horizontal mounting with a 4 m protection field range and 70/150 mm resolution capability across 4 configurable protection fields. The transistor output switches the safety signal; the 4 protection fields let you define multiple warning and safety zones within the 4 m sweep, which is typical for mobile vehicle guidance or stationary hazard area monitoring where the floor plane must be scanned.
