Inductive prox with pigtail and M8 QD

Can anyone suggest a source for an M8 threaded barrel prox sensor (24VDC) with an M8/Pico quick disconnect? The catch is that QD plug needs to be on a pigtail (say 4" or so), not part of the sensor housing. I know these exist because we have them on some existing equipment, but the tag information is worn off. We need the pigtail due to space restrictions.

Balluff maybe

Exactly what I need, thank you.

I just found out that the sensor I have is a Robohand OISP-011. They are available from Omega but I've never heard of that brand so I'll probably go with the Balluff.
