Color coded wires

Postby marta2393 » Thu Aug 25, 2016 9:27 am

Hello,

I've recently bought a respiration sensor with a 4-pin Molex Sherlock cable, but I need to do some adaptations to my experimental setup, which involves knowing what is each wire exactly. I know they are color coded but sometimes these things can vary...

I guess that black-neutral, green-ground, red-signal, yellow-power (3.3V for this sensor)

Could you confirm this information?

Thanks in advance!

Hi,

Are you using the version with an RJ, a Molex Sherlock or a UC-E6 connector?

You can check the physical appearance of the Molex and UC-E6 connectors here:

The RJ connector model looks like this:

I have already a sensor with a 4-pin Molex Sherlock, but I don't want to connect it directly to bitalino, so I wanted to know what each wire is. Given that the respiration sensor (as well as the other sensors) is differential, I realize that three of the wires in this cable correspond to the Ref, In+ and In-. What I don't understand is what is the 4th wire? It didn't existed in previous versions of this connector (which were only 3 pins)... and it seems that even if I wanted to solder a 4-pin Molex Sherlock socket to the board (even the newest one), there are only three input pins available.

Sorry if I'm making some sort of confusion

Best

The 4th wire is the analog output coming from the sensor.

In the sensor version with the 4-pin Female Molex Sherlock connector, the pinout should be as follows:

BLACK - GND (0V)
RED - VCC (e.g. 3.3V)
GREEN - REF (VCC/2)
YELLOW - OUTPUT

Hello Bitalino Team,

I just received a package with open wires UCE6 cables. There are 5 colored cables. Can you tell me the pinout?

Best,
Peter

Hi Peter,

In the UC-E6 breakout cable, the pinout should be as follows:

BLUE - GND (0V)
RED - VCC (3.3V)
COPPER - REF (VCC/2)
COPPER & COLOR - SIGNAL
GREEN - NOT USED

Thank you very much! Maybe it would be helpful if you integrate these pinouts (for the others, too) in the description of the cables :)

Best,
Peter

Hi Peter,

Thanks for the advise... we'll add a data sheet to the website and point to it from the product page on our web store.
