Hello, In my design the mounting plate for sensor coil is a metal which i cannot change to other material. Mounting plate size is also large. I have only 7mm gap between Target metal object & sensor coil mounting plate between which i have to place Sensor coil PCB.
The only design aim is to sense presence of target metal object & there should be least variation in the LDC count at every measurement.
with 1.6mm thick PCB, I will keep distance between target metal object & sensor coil as 2mm & that with mounting plate metal 3.4mm.
will that be ok to sense target metal object presence?? is there any other way i can improve the sensing, for eg: ferrite sheet on base mounting metal plate etc...??
