Grayhill Updates CANbus Keypads, MMI Controllers

Grayhill CANbus keypad
Grayhill MMI Controller

LAGRANGE, Ill. – Grayhill Inc. released an updated version of its CANbus keypads and MMI Controllers for off-highway vehicles.

With many available standard form factors and three standard legend sets, the new Grayhill CANbus keypads and MMI Controllers are made to be customized. Designers can change legends, backlight LED indicator color, and button configurations.

The keypads and controllers now feature a lower profile that protrudes from the panel only about half the distance as the original versions.

A new snap-fit feature means the keypad and MMI Controllers can be easily installed into the panel cutout without tools. New safety diagnostic functions actively report the status of incoming power and the functionality of buttons/LED indicators. The low-power sleep mode saves energy, and LED indicators are now raised above the buttons, enhancing visibility.

In addition to adding the number of sizes available, Grayhill also expanded integration options with input/output (I/O) pins that can be controlled by the CANbus interface for door lights, heat sensors, and other analog outputs.  

Key advantages include:

  • Five standard keypad form factors available
  • J1939 and CANOpen Safety versions
