Griessbach offers variable input modules with CAN bus interface for uncomplicated installation and network connection in vehicles and mobile machines. The keypads, which are available in various scales with four to twelve input fields, are particularly suitable for users who only require small quantities and want to keep their own development costs to a minimum. As standard, the operating elements equipped with short-stroke buttons can be individually configured with a foil design according to customer requirements. Backlit pictograms and two LEDs each for status display enable clear operation. On request, the standard modules are also available with actuation protection or special embossing for precise finger guidance. Additional interfaces for connecting peripheral devices, such as brightness sensors or external switches, can be integrated as an option. A sturdy housing design with frame surround protects the operating front against the ingress of dust and moisture in accordance with IP65. The devices, which are available in different dimensions depending on the number of buttons, have clamping springs attached to the housing and can therefore be snapped into appropriately dimensioned installation openings without vibration.
