Under the brand name SIRIUS ACT, Siemens offers a unique portfolio of control and signaling devices with worldwide product approvals in three modern design series made of robust genuine 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-rotation feature is already integrated. Thanks to the consistently high protection class, the robust devices are industrial-grade and suitable for outdoor use. 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 supports the selection and ordering of individual devices, enclosures, and labels. Extensive documentation (e.g., manual, 3D data, connection diagram) is available. Available versions: 30/40/60 mm mushroom diameter, several colors, illuminated/non-illuminated, latching/pressing actuation, pull/turn release. Note: Individual device, holder, and modules must be ordered separately. SIRIUS ACT - Performance in Action for control and signaling. Easy to install, simply strong, simply perfect.
