Hi,
I just received my counter but there’s no power supply unit include.
Is it the good item to order:

for this sensor:

Hi Frederic,

What was your online order number? I’d like to see if you purchased the sensor with external power option.

If you did then yes, that would be the correct power supply. It is simply a 12VDC regulated power supply with a 2.1mm barrel jack connector(center pin positive).

Thank you,
