Enclosure for 4-position knob, coordinate, ID key switches, and sensor buttons, 22 mm, round. The enclosure material is plastic, with a gray top, featuring 1 command point in plastic, without any components, designed solely for front panel mounting. The SIRIUS ACT enclosure is intended for the installation of 22.5 mm control and signaling devices in spatially separated arrangements of control units and switch cabinets. Under the brand name SIRIUS ACT, Siemens offers a unique portfolio of control and signaling devices with global product approvals in three modern design series made from robust real metal and high-quality plastic. The innovative snap-on concept simplifies installation to the extent that only one hand and no special tools are required. For mounting holes, non-threaded holes are sufficient, as a 100% anti-twist protection is already integrated. Thanks to the consistently high protection class, these robust devices are suitable for industrial use and outdoor applications. Even cleaning with high-pressure jets is possible. Neither dust, oils, nor aggressive alkalis can disrupt reliable operation. In addition to standard wiring, most devices can also be connected to the control system via PROFINET, AS-Interface, or IO-Link. This reduces your wiring effort, minimizes sources of error, and provides greater flexibility. The graphical online configurator conveniently assists in the selection and ordering of individual devices, enclosures, and labels. Comprehensive documentation (e.g., manual, 3D data, connection diagram) is available. Available versions: yellow/gray, plastic/metal, 1-6 command points, empty enclosure/pre-equipped, optionally with AS-Interface connection. SIRIUS ACT - Performance in Action for commanding and signaling. Easily mounted, simply strong, simply perfect.
