3-Position Micro Quadlok Receptacle Housing — Violet Keying
The violet color serves as a visual keying aid in multi-connector harness assemblies, reducing the chance of mismating on the line.
What the Violet Housing Means for the Harness Build
The violet color is not cosmetic — it is a deliberate keying feature. In a harness with multiple Micro Quadlok housings (e.g., blue, black, violet), the color tells the assembler which mating half goes where without reading a cavity number. The glass-filled PBT gives the shell enough stiffness to survive repeated mating cycles in an interior automotive or appliance environment, though the 80°C upper limit means it stays out of under-hood or high-temp industrial zones.
The 3-1718346-1 is the same 3-position, 0.100"-pitch Micro Quadlok receptacle housing in blue. Pitch, material, mounting style, and contact type are identical. The only difference is the color — violet vs blue — which matters only if your harness color-coding scheme calls for one over the other. Both are Active and RoHS compliant. If you already have blue housings in the BOM and need a visual distinction for a different circuit, the violet 4-1718346-1 gives you that separation without changing the footprint or terminal.
