Panel-Mount Receptacle Housing, 12 Circuits, 3 Rows
It snaps into a panel cutout and secures with a locking ramp — no tools needed for the mount, but the ramp gives an audible click that tells you it's seated. The natural PA66 housing carries a UL94 V-0 rating typical for this class, so it's fine inside equipment enclosures where flame rating is specified.
The matching plug header from the Mini-Universal MATE-N-LOK family completes the pair — same 4.20 mm pitch, same locking ramp interface. The crimp termination means you'll need the proper applicator and die set for the wire gauge you're running; TE publishes crimp specs for each terminal in this series. The 3-row layout gives you 12 circuits in a compact panel footprint, which is useful when you're routing multiple signal or low-power lines through a single bulkhead pass-through.
