Another possible solution to this issue could be the LDC1312 or LDC1314 devices implemented as in TIDA-00615 for rotary encoding. It may not work for you, but I wanted to bring it to your attention.
Part Number: LDC2114 Other Parts Discussed in Thread: TIDA-00508 , LDC1101 , TIDA-00615 , LDC0851 , TIDA-00828 HI Sir
We would like to use LDC2114 to do below application
Due to this application will use 2 pcs of alkaline battery and need to support…
Hello Lorenzo,
If you have a metal target that is rotating a fixed distance from your PCB then you can use an LDC device such as the LDC1612 (slower speeds) or LDC1101 (fastest speeds) to detect the speed.
I would take a look at the following TI Designs…
Hello Kiran,
Inductive sensing can be used for both rotary switch applications and push button switch applications. I would recommend to take a look at our design collateral:
