Control heads, lighting units and labelling elements form the interface between the operator and the machine. These HMI accessories enable a modular design and the retrofitting of control units in accordance with IEC 60947-5-1.
Operating heads for a 22.5 mm installation dimension: The range includes flat pushbuttons for space-saving layouts, raised versions with improved tactile feedback, mushroom-shaped emergency stop buttons and handle-operated selectors. All actuators are designed for industrial environments with high switching frequencies.
LED light sources and lamp holders: The 24 V versions are available in the standard signal colours: red, yellow, green, blue and white. Lamp holders with bayonet or screw fittings allow faulty bulbs to be replaced without the need for tools.
Labelling elements: Polyester signs are suitable for temporary labelling, whilst aluminium versions offer long-lasting protection against abrasion and chemicals. DIN-compliant symbols for start, stop, direction of rotation and warning are available as ready-made sets.
Blinds and blind plugs: For unused 22.5 mm cut-outs, the covers protect against dust and moisture whilst maintaining the clean appearance of the control panel.
Screen protectors: The transparent films protect sensitive HMI touchscreens from scratches and chemical damage without restricting their usability.
In automation technology, these accessories are used to customise machine controls in line with specific process requirements. In retrofit projects, the modular components enable the step-by-step modernisation of existing control cabinets. Maintenance engineers use the range for quick repairs and the replacement of worn-out control elements. In the range: RAFI.
