The illuminated square keys are made to be an important component for machine and system manufacturing in demanding work environments. They can be illuminated in five colors (red, yellow, green, blue and white), and various combinations of single-color and multi-color keys are possible. The light fixture developed by B&R provides for uniform illumination of the key, which increases the readability of the key label. The labels can be printed directly on foil or installed as legend strips – and the user profits from maximum design freedom.
Made of a short-stroke key, a light fixture and high-performance LEDs on a circuit board, the illuminated square key can withstand up to 1 million actuations. The key can be implemented with different embossing depending on the requirements, which provides the key with an excellent tactile feel. The 16 mm diameter of the key actuating area and a minimum spacing of 30 mm between keys provide additional operating comfort.
The hygienic surface design – no gaps, edges or joints – gives the key modules ideal operating elements in environments where the highest level of sterility and cleanliness are required (e.g. in the food industry or the pharmaceutical industry). With IP65 protection, the modules can also withstand the harshest industrial conditions.
The various illuminated keys can be implemented in the complete system in many ways using all B&R technologies (such as Automation Panel, Power Panel, Panelware, etc.). This allows entry devices to be placed at various positions on the machine. Four different types of modules permit placement anywhere on the machine, and distances of up to 100 m can be bridged between the individual modules.
With a B&R bus controller, the key modules can be easily connected to all standard bus systems such as Profibus DP, POWERLINK, EtherNet/IP, CAN (with CANopen and DeviceNet protocols) and ProfiNet.
