Accepts .062" (1.57mm) nominal thickness P.C. Board
Low profile insulator body design
.156" (3.96mm) contact spacing with single centreline row

Applications

Industrial control systems
Telecommunications equipment
Consumer electronics assemblies

Procurement Notes

Verify the specific contact plating requirement against project specifications, as distributor listings may vary between tin and gold finishes for this part number. Confirm that the dual-edge female configuration aligns with the mating card edge design. Ensure the through-hole termination method is compatible with the assembly process. Check regional availability restrictions as some distributors may not stock this item locally.

Selection Notes

Select this component when a low-profile card edge solution with 3.96 mm spacing is required. The dual-edge configuration supports higher pin counts within a compact footprint. Verify that the board thickness tolerance matches the 1.57 mm specification. Consider the tin plating if cost efficiency is prioritized over high-cycle durability compared to gold alternatives.

Part Context

This connector belongs to the EDAC 306 Series, which provides standard density card edge solutions. The series offers various position counts and mounting styles. The 306-026-421-178 specifically utilizes a green insulator and tin-plated contacts, distinguishing it from gold-plated variants in the same family.
