The 40 mm width fits standard mounting footprints for guard-door or limit-switch applications where AS-Interface bus communication is needed at the switch point. The ASI-F-adapter integrates the position switch directly onto an AS-Interface safety-at-work bus, eliminating a separate I/O module for the switch point. The single NC contact provides a normally-closed signal path that opens on actuation — the standard fail-safe wiring for guard monitoring. The angular roller lever with metal construction handles repeated cam or slide actuation on automated doors, guards, or transfer stations without the creep or wear of plastic rollers. ## Deployment Context Mounts on machine guarding or transfer-line stations where the roller lever follows a cam profile. The ASI-F-bus connection runs a single two-wire cable for both power and data, reducing field wiring compared to a conventional limit switch run back to a safety PLC input card. The 40 mm width matches standard switch mounting hole patterns for retrofit into existing guard-door positions.","metaTitle":"Siemens 3SF3120-1FV00-0BA1 Position Switch with ASI-F-Adapte","metaDescription":"Siemens 3SF3120-1FV00-0BA1 position switch with ASI-F-adapter, 1 NC snap-action contact, angular roller lever metal, width 40 mm.
