Rugged Enclosure

  • IP-30 rated rugged case protects the device in any environment from industrial to office.
  • IP (International Protection Rating) Code specifies that objects greater than 2.5mm in diameter cannot penetrate the case. This means that the case provides a safety barrier from objects (such as tools and wires) interfering with the internal circuitry.

Integrated Wall Mount

  • All Brainboxes' light industrial serial Ethernet adapters feature integrated wall mount points which are located on either side of the device (also known as Ears).
  • Screws or nails can be used to attached the device through the wall point ears to a wall, table or any firm flat surface.

Optional DIN Rails Mounts

  • The DIN rail mounts are an optional accessory. This allows the device to be mounted in a Server rack or any DIN rail fitted equipment rack. The DIN rails conform to IEC International Standard 60715 and European Standard EN 50022.
