Sensor impedance


I want to connect the " IoT Long Range Wireless One Channel Counter Transmitter" sensor in parallel to an already existing counter input of a PLC. But to make this work, the sensor must have a very high impedance (around 1MOhm). Does somebody know where I can find impedance info of the sensors ?

Thanks :slight_smile:


Hi Bert,
The impedance is around 3MOhm. ( i pulled this value from the controller datasheet never measured-or calculated by myself)


Thank you Bhaskar.

Have a nice day
