Hi, I have this inductive rotary sensor with printed coil on PCB. It has three pinouts - Vcc, GND and Out. Unfortunately I don't have any datasheet for this product. When connecting 5V and GND to respective pins, I measure about 3.4-3.5V across Out and GND pins. This value doesn't change when the…

I was measuring the out voltage using a multimeter.

Can you supply a photograph of this sensor please.

Thanks, not seen that sort of sensor before. How did you know what wires were 5V and ground? Most inductive sensors work on current draw. That is there is more current draw from a coil close to metal than not close to the metal. I did expect the disc however to that shape. There will be an oscill…

Thanks @Grumpy_Mike Those Vcc, GND and Out pins were indicated by seller but he wouldn't provide more information. I have tried 12V as well but output voltage doesn't change when I rotate the disc. I am not sure I understood the resistor connection you mentioned. Do you mean to attach 10K across…

Consider asking the seller for more information, or post a link to the product page.

@jremington I wish. Its an automotive part. Local seller has no idea how do I read the data nor any information is available online.

You need to scope the OUT lead while spinning the reluctor at a steady, reasonable clip (VSR drill or drill press). Guess is you'll get a PWM pulse train. What exact (year/make/model) vehicle is it out of? The vehicle service manual should list a field test procedure and circuit.

@madmark2150 This is the amazon link .

[image] zeus2kx: Do you mean to attach 10K across Out and GND pins? No. I said:- [image] Grumpy_Mike: What I would try is to connect the three signal outputs to ground, through a resistor and measure the voltage across the resistor. through a resistor. That means, signal output -> res…
