Grayhill designs and manufactures rugged human-machine interface components and control systems for military, medical, industrial and off-highway vehicle applications. Its product portfolio includes rotary switches, optical and mechanical encoders, Touch Encoder™ devices, joysticks, keypads, pushbuttons, DIP switches, CAN-bus displays, CAN-bus keypads, vehicle interface controllers, I/O modules and customized control panels. Grayhill combines mechanical design, haptics, ergonomics, sealing and electronic communication to create operator interfaces for harsh environments. Many products are designed for high cycle life, environmental sealing and demanding mechanical or electrical conditions. Current developments include the VectorPad compact directional keypad for space-constrained rugged panels and CliniKey™ medical panel-mount keyboards designed for repeated cleaning with harsh disinfectants. Grayhill also continues to expand CAN-based HMI solutions and customizable display/control assemblies. For engineers, Grayhill provides both component-level controls and vertically integrated custom HMI development, including tooling, molding, testing and manufacturing. Mechanical and electrical integration are equally important in these products. Engineers typically need to consider contact resistance, current and voltage rating, operating force or tactile response, cycle life, sealing, mounting method, PCB footprint, panel geometry and environmental exposure. The manufacturer’s product families provide alternatives for designs where operator feel, mating reliability, space constraints and service life are part of the electrical specification. This makes early coordination between mechanical, PCB and system engineers particularly valuable during component selection. The official manufacturer website provides product-level technical information that can be used to compare available families and identify the most suitable technology for the intended electronic design. For Israeli engineering teams, Boran Technologies can support product identification and local commercial coordination for this manufacturer.
