Hello,
I am looking for a replacement for a Magneto-resistor type potentiometer model SMP-1504 by manufacturer SAKAE TSUSHIN KOGYO CO., LTD. I have already contacted them but they no longer manufacture this type.
What the manufacturer have are inductive types which they say is analog output and is not compatible with the Magneto-resistor type which is digital output. I am not sure why is it not compatible that but I did test it with according to specs input voltage of 5vdc and its out of 1.5v min and 4.5v max is according to specs also.
The potentiometer turn together when the DC motor turns through a belt.
The input of the potentiometer is from a 5vdc reference voltage and the output is into an OpAmp as indicated in the red arrow.
Please help me analyze and suggest a replacement for this. Many thanks to all of you.
