*Custom Integration - ErgoNav EGN-D Series can be customized per the design rules and limitations:
-Nav-disc diameter and actuator height (scalable per the design rules)
-Nav-disc actuator (plastic or silicone; color, surface texture, fashion; process Integration)
_Nav-disc plastic retainer (integratable to device chassis per the design rules)
_Nav-disc silicone sensor pill and pad (process integratable to device membrane elements per the design rules)
-Dedicated microcontroller (contains firmware for quick I/O interface, or firmware compiled into device controller)
