300 mA in Digital Pin to Arduino

Hello friends

I have a inductive type proximity sensor. The output of the sensor is given as 300 mA in the specs as well as in the data sheet of the device

Sensor bought from Amazon - CLICK FOR AMAZON PRODUCT PAGE

Can I directly connect the output of the sensor to the Arduino Digital which supports 5 V ?

Do I need any resistors to change the 300 mA to 5V signals ? If so what resistor should I use ? The connection must be made in serious or parallel ?

I am new to electronics . Thanks for your time

This is simply saying that the output of the sensor can sink UP TO 300mA.

To interface to the Arduino simply fit a 10k resistor from 5v to the digital pin and connect the output of the sensor to the digital pin. When the sensor is active it will act just like a switch and take the pin to ground.

You can also use the internal R to tie the input high.

Note that the supply required to power the sensor is 6 - 36v so you will need an external supply rather than running off the 5v supply. Make sure the gnd is connected to the Arduino gnd.
