Plastic I/O cover with rubber seal. Advantech mounting kits are the perfect choice for securing MDTs (mobile data terminal) to vehicles on the move. The mounting kits come with two plates and double socket arms which can absorb harmful shocks and vibrations. They are designed to absorb a shock of up to 40G, 11ms (MIL-STD-810G) or 100G, 6ms (EN60721-3-5) and will hold MDTs solidly in place even in the harshest of conditions. View angle and position of MDTs is fully adjustable by the double socket design. All RAM components are interchangeable, so if you decide to switch items from one vehicle to another, simply swap them out with a turn of the knob. There are many different, non-destructive RAM mounting bases that will quickly attach and fit different vehicle cabins. They have been tested on vehicles from Toyota, CAT, Daewoo, Komatsu, Yale, Hyster, Clark, Mitsubishi, Nissan and many others.
