2.9 - OEM Versions [U12 Datasheet]

The LabJack U12 is also available in 2 OEM (original equipment manufacturer) versions:

LJU12-PH: This is a populated LabJack U12 PCB with pin-headers installed (on the component side of the PCB) instead of screw-terminals. Also, the LED is installed on the component side of the PCB, so nothing is installed on the solder side.
LJU12-NTH: This is a populated LabJack U12 PCB with no through-hole components (DB25 connector, USB connector, LED, screw-terminals). This board is meant for OEMs who solder connections directly to the PCB, or wish to install only certain connectors.

Dimensional drawings are available here. The pin-header pinouts can be found in “LabJack_U12_PH-NTH_Dimensions.pdf” which is in “u12dimensions.zip”.

Normally, nothing ships with these OEM LabJacks except for the populated PCB. All software is available online on the .

PCB Revision C (J1 and J2 alternate pinout)

Important!

Revision C of the U12's PCB features an alternate pinout for OEM headers J1 and J2. This revision is currently only sold with an enclosure and not as an OEM version, so this change will not be an issue for most users.

To identify PCBs with the alternate J1 and J2 pinouts, please see the image below.

If you plan to remove a Revision C U12 from its enclosure and use these headers, contact support@labjack.com for assistance.
