The Siemens 3SF3200-1DV00-0BA1 is a position switch with an integrated ASI-F-adapter, carrying one normally-closed snap-action contact actuated by a roller plunger. The moulded plastic housing is 31 mm wide, sized for standard mounting in safety gate or position-sensing applications along a machine perimeter.
The ASI-F-adapter integrates the switch directly onto an AS-Interface safety network, eliminating a separate I/O module at the guard point. The single NC contact provides a hard-wired safety signal that, when opened by the roller plunger, reports the guard position to the safety monitor over the AS-i bus. The 31 mm width fits alongside other AS-i nodes on the same mounting rail.
