Product Specification CAN-bus Keypads Description The MICO CAN-bus keypads interface with MICO MOBEUS ABS/TC/ESC controller for multicolored status indication and operator control. With its simplified design, the keypads save ECU inputs and simplify vehicle wiring. Custom keytop legends and larger form factors are available. The MICO CAN-bus keypads are designed for Off- Highway vehicles and fully compatible to the SAE J1939 CAN communication standard. The indicators and legends are dimmable and sealed to IP67. The keys are designed for long life (1,000,000 cycles per key), vibration and impact resistant, and support 12/24 volt systems. MICO is a trademark and registered trademark of MICO, Inc. MICO is registered in the U. S. Patent and Trademark Office as well as in Australia, Canada, Indonesia, Japan, Peoples Republic of China, South Korea, and the European Community.
