The 2188698-1 is designed specifically as a “Mixed & Hybrid” connector. The different cavity grids (0.5mm and 1.5mm contact sizes) allow engineers to route high-current power lines through the larger terminal points and low-current data or sensor signal lines through the smaller, closely spaced 2mm pitch grid. This hybrid nature eliminates the need for separate signal and power connector breakouts.

No, this product is an unsealed connector housing (Sealable: No). It does not include an internal silicone perimeter seal or individual wire seals. It is engineered primarily for indoor automotive cabin compartments, protected electronics enclosures, or dashboard wire-to-board modules where it is completely safe from direct rain, mud, or pressure washdowns.

The black component is part of the integrated primary locking structure. While the housing itself uses standard flexible plastic clips to guide the mating male header, this slider block provides structural reinforcement once the connector is fully inserted. It prevents accidental disengagement caused by continuous mechanical stress and vibration typical in passenger vehicle operations.
