Simple, non-slotted holes are sufficient for the mounting holes, as 100% anti-rotation protection is already integrated.\nThanks to the high degree of protection, the robust devices are suitable for industrial and outdoor use. High pressure jet cleaning is even possible. Neither dust, oil nor lye can compromise their reliable operation.\nIn addition to standard wiring, the devices can also be connected to the controller via PROFINET, AS-Interface or IO-Link. You can thus reduce your cabling effort, minimize sources of error and gain greater flexibility.\nThe graphical online configurator conveniently supports the selection and ordering of individual devices, entrance panels and registrations. Comprehensive documentation is available (e.g. manual, 3D data, connection diagram).\nSuppliable versions: mushroom head diameter of 30/40/60 mm, multiple colours, illuminated/non-luminous, permanent/pulse control, push-button unlocking traction/rotating.\nWarning: Single device, holders and modules must be ordered separately.\nSIRIUS ACT - Performance in Action in control and signaling. Simple to assemble, highly performing, simply perfect.
