New Series 84 IO-Link Touch touch-operated devices are capacitive rugged , bright and configurable
The trend towards digitisation of Human Machine Interfaces in the industrial sector is leading OEMs to adopt radically new approaches to machinery design and manufacture . At the same time , digitisation is creating an even more intensive working environment for operators of the equipment
Mindful of these requirements HMI specialist EAO Ltd has introduced a new family of capacitive switches that enable new generations of digital machine systems to be intelligently connected via an IO link controller to higher level bus systems or a programmable logic controller ( PLC ). Targeting new and emerging factory automation applications the new Series 84 IO-Link Touch touch-operated switches are freely configurable , bright and uniquely , jetwash sealed to IP69K .
According to Robert Davies , Marketing Manager with EAO Ltd ., machine manufacturers must overcome demanding challenges in order to fully digitise their designs , not least in terms of system complexity and the enormous investment required : “ Thanks to the globally established IO-Link communication interface and programmable connection options , our new Series 84 IO-Link Touch touchoperated switches can be networked via an integrated M12 5-pin screw connection , rendering the equipment Industry 4.0 compliant ”, Davies said . “ Series 84 IO-Link Touch switches require a mounting depth of just 25.8 mm ”.
Application-specific yet highly configurable EAO offers the new Series 84 IO-Link Touch switches in three HMI variants – standard , stainless steel and hygiene – together with a range of application specific actuators and indicators , rendering the new family of switches ideal for a wide range of mechanical engineering applications .
“ The many potential uses for Series 84 IO-Link Touch switches centre around their freely selectable configuration capability , which can be precisely aligned to the respective application – from illumination , to symbols , to the switching function ”, Davies continued . “ For example , the illumination can switch on with a deliberate delay when actuated , and HMI operational readiness can be signalled by green illumination , which changes to yellow when actuated and then to red a few seconds later . The configuration remains stored on the HMI even with no power supplied ”.
Innovative RGB LED illumination . Four lateral illuminated windows integrated into the front frame of Series 84 IO-Link Touch switches ensure excellent visibility of the entire status display . The static or flashing RGB LED illumination is particularly bright and thanks to the integrated ambient light level sensor , is always illuminates at the right intensity for a particular lighting condition . This feature also optimises the HMI ’ s power consumption as well as LED lifetime . High contrast , optionally illuminated standard or custom symbols combined with their attractive design means the new IO-Link Touch switches are able to visually integrate into any modern application setting .
