The rating is only zero to seventy degrees — is that enough in a closed box?

That window suits an office cabinet, not a sealed outdoor enclosure. Our test box rises about fifteen degrees above room with the lid on, so we measure the jack body rather than the air and keep margin at the top of the range. If the housing runs hotter, ask for the industrial version of the same footprint instead of adding a fan.

Only four cores are wound — what happens to the unused pairs?

Pairs one-two and three-six carry the link; the remaining four contacts are still terminated inside the part through the Bob Smith network, so they must not be left floating on the board. We keep that return tied to a quiet ground and confirm it with a continuity check on the first piece. Leaving them open shows as common mode noise on a scan rather than a dead port.

How much room does a downward latch need under the cutout?

The clip swings below the mouth, so the strip of bezel directly beneath the opening has to stay empty for a thumb. We mount a booted cord, seat the board, and check the release by feel before signing the drawing. On one chassis a folded tab sat in that band and trapped the clip, so the metal shop cut it away rather than us re-spinning the PCB.

Which lens shows the link and which one blinks on this jack?

The pair is yellow and green, and the housing does not decide what either means, so our house rule is green for a live link and yellow for frame traffic. Write that rule into the firmware header and the assembly note together, because a second line will otherwise swap them and every field engineer will read the panel backwards.

Q:

Our test box rises about fifteen degrees above room with the lid on, so we measure the jack body rather than the air and keep margin at the top of the range.

Door readers in our office block use these, and the clip under the board keeps the cable out of the reader nose. Nice and tidy :-)

We compared three bodies on one board and picked this one because the lamp pair sits higher, leaving room for a wide label strip. The 13.40 by 15.90 outline matched the other parts, so no layout change. Shield tabs pressed flat and the scan came back low. Every reader we built has been stable.
