Push button, 22 mm, round, plastic, black, 40 mm, forced locking, in accordance with DIN EN ISO 13850, rotary release. SIRIUS ACT push button with a large actuator for comfortable operation with the whole hand. 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 100% anti-rotation protection is already integrated. Thanks to the consistently high protection rating, the robust devices are suitable for industrial use and outdoor applications. Even cleaning with a high-pressure jet 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 operation, pull/rotary 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.
