The SIRIUS ACT key switch offers a higher standard of access security. Under the brand name SIRIUS ACT, Siemens provides a unique portfolio of control and signaling devices with global product approvals in three modern design series made of 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, the robust devices are suitable for industrial use and outdoor applications. Even cleaning with high-pressure jets is possible. Neither dust, oils, nor aggressive caustics 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 comfortably assists in the selection and ordering of individual devices, enclosures, and labels. Extensive documentation (e.g., manual, 3D data, connection diagram) is available. Available versions: various locking systems, 2/3 switching positions, latching/push-button operation, various key withdrawal positions. Note: Individual device, holder, and modules must be ordered separately. SIRIUS ACT - Performance in Action for control and signaling. Easily mounted, simply strong, simply perfect.
