The Siemens 3SF3100-1GW00-0BA2-ZA16 is a position switch with an integrated ASI-F-Adapter, carrying a single NC slow-action contact and a roller crank actuator. The M12 connector simplifies field wiring, and the metal housing (width 56 mm) holds up in industrial environments where plastic enclosures crack.
Integration & Deployment
The roller crank actuator suits cam-operated or slide-gate positions where the switch is tripped by a moving machine member. The NC slow-action contact (1NC) provides a positive-break safety function — the contact gap is mechanically forced open even if the contacts weld, which is the usual requirement for safety interlock circuits on guarding doors or access covers. The M12 connector mates directly to standard sensor cables, saving panel space compared to a terminal-chamber version.
Reference Code
The IEC 81346-2 reference code is B, which classifies this component as a switch or sensor in the plant documentation system. Useful for panel builders who tag devices per that standard — the B code goes on the label next to the terminal designation.
