Impact Blade Power Receptacle, 4-Position Press-Fit
It is a blade power connector style, meaning the contacts are flat blades designed to carry higher current per circuit than a standard signal pin. The press-fit termination eliminates soldering — the compliant pin compresses into the plated through-hole on the backplane, giving a gas-tight joint that survives rework cycles without thermal stress.
What the Press-Fit Termination Means for Assembly
Press-fit termination means this receptacle is designed for a solderless backplane assembly process. This avoids the thermal shock of wave or reflow soldering, which can warp large backplanes or damage nearby components. It also makes field replacement simpler — a damaged connector can be pressed out and a new one installed without desoldering. The trade-off is that the PCB hole size and plating thickness must match the pin geometry specified in the TE application drawing; an undersized hole can damage the pin, an oversized one loses retention force.
The 4-position count and blade power layout are specific to this Impact-series variant; confirm the mating half (the corresponding Impact header) and the backplane footprint before committing the BOM line.
