3. Fasten the unit with the eight 4-40 hex nuts that were removed in Step 2.
General Mounting Recommendations
If the OP7100 is mounted inside a panel, the enclosure must not be airtight
to ensure that the touchscreen will not distorted by differences in air
pressure. If the OP7100 is mounted in a completely airtight enclosure, a
pressure differential may build up across the window overlay, and could
adversely affect the operation of the touchscreen.
Tip
Carefully tighten the nuts equally until the gasket is compressed to
approximately 75% of its uncompressed thickness of 0.125" (3.2 mm).
Do not tighten each nut fully before moving on to the next nut
since this risks distorting either the panel or the bezel (or
both). Apply only one or two turns to each nut in sequence
until all are tightened to the required amount.
In order to seal the bezel against the panel, the gasket must be
compressed by the pressure of the mounting nuts. If the panel
is very thin (<0.06" or 1.6 mm), this pressure may distort the
panel, allowing water ingress. In this case, Rabbit Semicon-
ductor recommends using strengthening brackets between the
rear of the panel and the mounting nuts as shown in Figure 6-3.
