Part Number: LDC0851
One of my customers has designed a Pizza box sized switch. This is a standalone box and does not plug into any backplane. The power to this is through AC power chord. They need to detect the orientation of this box. It essentially has only 2 orientations- 0 or 180 when flipped.They need to sense this orientation in order to correct the front display according to the orientation.Can we use the LDC/FDC here in order to achieve this? Or any sensing solution form TI?

To detect 0 or 180 degrees, you could simply attach a metal surface to half of the box and place the SENSE and REF coils on either side. I've sketched up a quick drawing below.

In reply to Mahesh KC03:
The customer's/my concern is only about the moving parts and their reliability. If we can sense the orientation without having to make something actually move, it is more robust and error free. Here is the typical picture of the device. The display block is upright now and if the box is flipped(180 deg rotation), the Display will also flip 180.
Let me know what else we have.
The customer went ahead with a Tilt switch based approach to detect the orientation.
Thank you for the update. Please also note that the same approach (in terms of alignment) could be for the LDC0851, which is similar to an open/close application. Please take a look at the following 2 blogs for more info:
