The 1924678-1: Tin plating is cost-effective for applications with infrequent mating cycles — the 31.5µin (0.80µm) thickness on the mating face provides adequate wear resistance for field installation and occasional service disconnect.
The insulation height of 0.943" (23.95mm) is tall enough to accommodate a latch holder mechanism, which locks the mating connector in place. This latch holder fastening type is effective in moderate-vibration environments where a simple friction lock might disengage. Housing material is Polycyclohexylenedimethylene Terephthalate (PCT), a high-temperature thermoplastic suitable for lead-free reflow profiles. The black insulator provides visual contrast for automated optical inspection.
It is RoHS3 compliant.
