Our largest X-keys, the XKE-128 offers eight rows and sixteen columns in a ¾” grid to create the perfect control panel for any application. Single units stand readily available for experimentation and prototyping. We support every customer from initial purchase and prototyping through the implementation of multiple control consoles.
The XKE-128 ships fully populated with 128 relegendable keys - perfect for testing multiple layout options. Add optional large keys and key blockers to refine the layout. Using an established hardware platform saves time moving from prototype to production.
When it comes time to reproduce your finished prototype, select options ranging from printed key legends to acrylic printed ABS keys to double-shot molded keycaps. We offer custom brand labeling, assembly, programming, and testing to provide a delivered plug-and-play solution. We specialize in 10-100 unit custom control solutions with the capability to step up to thousands of units for large scale deployment.
