The front frame is modified customer-specifically on the “rear-mounted devices":

The surface with the display viewing area covered with decorative membrane, and the marginal area around the display necessary for touch operation must be flush with the control cabinet sheet metal at the front. For this purpose, the front frame with the device seal and the cutouts for the holding bolts are set back from the visible surface by the thickness of the control cabinet sheet metal. The enclosure must have a suitable number of stud bolts available. The all-round device seal thus enables a high degree of protection: IP65.

The installation cutout can be dimensioned in such a way that the rear-mounted device can be replaced with the same type of front-mounted device for service purposes.

The decorative membrane is also drawn across the visible area of the display on the rear-mounted devices, so there is no cutout with adhesive edge above the display. The decorative membrane is smooth.

For sensitive applications where the gap dimension of the control cabinet cutout has too great a tolerance, there is the option of covering the entire surface including the gap with a transparent and replaceable membrane.
