The 12124580 socket and 12124582 pin terminals are built to the dimensional and performance requirements of the Weather-Pack sealed connector system. The contact geometry seats correctly within Weather-Pack housings and works in conjunction with the series' integral sealing design, making these the appropriate choice for applications where the Weather-Pack system is already specified.
[MATTE TIN-PLATED BRASS FOR LASTING CONTACT STABILITY]
The brass base provides the mechanical rigidity needed to maintain contact geometry under repeated mating cycles, while the full matte tin plating delivers a uniform, corrosion-resistant surface across both the mating and transition zones. Matte tin finish reduces the risk of tin whisker formation compared to bright tin plating, contributing to long-term contact stability in sealed environments.
[CONSISTENT QUALITY BACKED BY MULTI-STAGE INSPECTION]
Before leaving production, every terminal passes appearance inspection against crimp geometry standards, CMM-based compression ratio verification, and wire pull-force testing — a three-stage process that catches dimensional and mechanical non-conformances at the batch level rather than in the field.
[SIZED FOR MEDIUM-GAUGE AUTOMOTIVE WIRING]
With a wire range of 17-14 AWG (1.0–2.0mm²), maximum insulation diameter of φ3.96mm, and a 20A current rating across a -40°C to +125°C operating range, these contacts cover the medium-gauge wiring typical of automotive power distribution and control circuits where reliable current capacity and thermal stability are both required.
[ENGINE BAY WIRING, BODY ELECTRICAL & OUTDOOR EQUIPMENT]
Weather-Pack connectors are a long-established standard in sealed automotive wiring, and the ST6570 kit serves the technicians and assemblers who work with them daily — whether building new harnesses for engine management systems, repairing body electrical connectors, or wiring outdoor and marine equipment where moisture ingress is an ongoing concern.
