JMD Series 60-Position Mezzanine Plug
Gold finish on the contacts suits it for signal-level interconnects where multiple mating cycles are expected — the plating resists oxidation on the wiped surface better than tin would over repeated insertions. The connector is surface-mount with built-in solder retention features, meaning the SMT pads include extra metal anchors that hold the part in place through the reflow oven without requiring a separate adhesive or mechanical clinch. This is a practical detail for high-volume pick-and-place lines — the connector stays registered to the board pads during soldering, reducing tombstoning and skew. That 6 mm z-height is fixed by the shroud design — the boards sit at a consistent distance, which matters for enclosure clearance and for keeping the signal path impedance predictable across the interconnect.
At 0.50 mm pitch and 60 positions in two rows, the connector footprint is dense — expect fine-pitch PCB routing with trace widths and spaces that match the pad geometry. The outer shroud contacts are larger than the signal contacts and act as alignment posts; they take the shear load during mating so the fine-pitch signal pins don't bend on insertion. The "-G-1-TF(LF)(SN)" suffix indicates gold plating, tape-and-reel packaging, and lead-free reflow compatibility.
