It is not a standalone switch or actuator but the mounting and connection interface that brings pushbuttons, selector switches, or pilot lights onto an AS-Interface network. The 22 mm mounting diameter matches the standard panel cutout for industrial control stations, so it drops into existing operator panels or junction boxes without re-engineering the hole pattern. The enclosure is rated for vertical or horizontal fastening, giving flexibility in panel layout — mount it on a machine pedestal or a swing-arm console without worrying about orientation restrictions. The round installation opening is the standard 22 mm industrial cutout, meaning any 22 mm pilot device (pushbutton, selector switch, indicator light) from the same manufacturer family fits without adapters. This enclosure does not include an emergency stop function and does not provide positive opening of contacts — two critical distinctions for safety circuit design. If your application requires a positive-break NC contact for a safety-rated stop circuit, this enclosure alone cannot deliver it; you would need a separate safety-rated command device with positive opening mechanism wired through the AS-Interface gateway. The product component front ring is not included, and there is no integrated light source or provision for an optional light source. This is a bare enclosure — the buyer must specify the front ring and illumination elements separately if needed.","metaTitle":"Siemens 3SF5812-2A.
