Position switch with ASI-F-adapter
The Siemens 3SF3120-1DV00-0BA1 is a position switch with an integrated ASI-F-adapter, built for safety-related applications on AS-Interface networks. It carries one normally-closed snap-action contact, actuated by a metal roller plunger, in a 40 mm wide housing. The roller plunger design suits it for cam-actuated or linear-motion detection on conveyor lines, transfer stations, or machine guarding gates where a positive-break NC contact is required for the safety circuit.
