Unfortunately i was unable to find this sensor. Balluff discontinued this sensor for some reason, and i was not able to find a stock-house with this sensor. So i moved to plan B: First i downloaded the datasheet to see what sort of sensor is it:
It is a PNP N-O inductive sensor. I then called a friend of mine who imports the TURCK sensors, sent him the Balluff sensor details and asked him to find me something to replace it. This is what he sent me:
It is a cylindrical 6.5mm PNP N-O sensor. It does not have the rectangular part with the terminals but who cares? I will find another way to fix it into the housing.

| I received the sensors after 2 days! |
First i had to pair the wire colors according to the note that i took when i removed the original sensor |
Left is the Balluff sensor and right is the Turck sensor |
 |
 |
 |
 |
| First i cleaned thoroughly the surface with isopropyl alcohol to remove any dirt or grease |
Then i trimmed the sensor wires short |
I used a piece of tape to close the sensor's opening. |
Then i put the sensor in the sensor's hole. The sensor went all the way in until it reached the tape |
 |

 |
 |
| A 5-minutes super glue will certainly do the job! |
The sensor had to be all the way down in the sensor's hole |
The glue will hold it there for many - many years |
After the glue was cured, i removed the duct tape. You can see the yellow surface of the sensor |
 |
 |
 |
 |
| Time to connect the sensor. It is a good practice to tin the wires with solder paste |
I used also wire protection caps to ensure reliable operation under vibrations |
This is how the new sensor will be connected with to the wires |
A Klemmens connector ensures perfect contact |
Closing the sensor was tricky!
 |
 |
 |
| It was kinda tricky to fit all these wires in the housing |
Before fixing the screws, i made sure that all wire were in the housing and the sealing gasket was in proper position |
Finished! |
Just for the story, i went back to the customer and placed the sensor back again. It worked perfectly fine - The machine completed the reference cycle, i changed the reference position and everything worked like charm...
