What the ratings mean for the fit
The 0367590063: 12 A per circuit with tin-plated phosphor bronze contacts — the plating is consistent at 3.50 µm on both the mating face and the solder post, so current handling is uniform across the connection. The 0.550" insulation height gives the header sufficient standoff for through-hole soldering in industrial equipment where board conformal coat or potting may follow. Operating range is -55 to 105 °C, wide enough for most factory-floor and equipment interior deployments; the UL94 V-2 flammability rating means it cannot be used inside an air-handling space without additional enclosure or shielding. Board guide feature on the housing body helps alignment during blind-mate or production assembly — the locking ramp then takes the insertion load so the solder joints stay intact under vibration or cable pull.
