Inductive Proximity Sensor

Seshadri L

Dear Team,

I need help in designing an inductive Proximity Sensor, Metal detection range required is 22mm the operating frequency required is 500hz. unable to find an ic matching the specs, need help in designing the circuit.

Thankyou

Can you suggest any TI IC which matches the design requirements.

Seshradi,

The lowest frequency our inductive sensors support is 1kHz (LDC131x, LDC161x).
Can you talk about the general requirements for your application?
There may be other devices that will support what you want to do.

Regards,
John

Seshadri,

Thank you for the additional information.
We do not have a device that supports the 500Hz frequency you mentioned earlier.
Regards,
John
