E3JK-R4M1 Reflective Photoelectric Sensor Switch

Hi, thinking about buying this switch for a hobby project. Before I do, just checking if it is possible to connect it to Arduino Uno/Nano and how. Thanks.

It is a 12V 5 wire and it has a built-in relay output min 5V 10mA.

It has 5 connections:

1. Brown ... + power supply
2. Blue ... - power supply
3. White ... COM Relay
4. Black ... Relay Normally open
5. Grey ... Relay Normally closed

My idea:

1. Brown ... + external 12V battery
2. Blue ... - external 12V battery (and Arduino GND???)
3. White ... Arduino 5V
4. Black ... Arduino pin + 10kOhm to Arduino GND

Possible? Thanks
