With the Flexlab pushbuttons from Rafi's 'Rafix 22 FS' series, which can be individually labeled, machine builders reduce the time and effort required for planning or customer-specific adaptations of operating devices. Thanks to the variable, subsequent labeling option of the pushbuttons, function assignments that are relevant for the respective target application do not have to be taken into account at an early stage, but can be carried out at any later time - even by the end customer. In addition, the flexible labeling system allows the appropriate and correctly positioned labeling even if operating panels or individual operating devices have to be installed differently than planned due to changed installation conditions. The push-buttons achieve protection class IP65, can be illuminated and are available with a momentary or latching contact function. The push-buttons are available for a grid dimension of 30 mm x 30 mm with a square or round collar. Depending on whether the push-buttons are combined with PCB switching elements for PCB applications or with QC switching elements for wiring, the installation depth is 9.2 mm or 27 mm behind the front panel.
