Impact Backplane Header — 96-Position Press-Fit
The TE Connectivity 2057750-1 is a 96-position header from the Impact series, designed for high-density backplane and midplane interconnect. With 6 rows and 16 columns on a 0.075" (1.91mm) pitch, it packs a lot of signal paths into a compact board footprint.
Signal-Level Ratings, Not Power
Rated at 0.75A per contact and 30VAC/DC, this is a signal interconnect, not a power delivery connector. The 0.75A per circuit means each pin carries logic-level or low-current I/O — think differential pairs, control signals, or low-speed data lines. The 30V rating confirms it's for signal-level voltages inside equipment, not for bus bars or motor drives. If your BOM calls for carrying more than an amp per circuit, this isn't the right header.
Press-Fit and Board Layout
The press-fit termination drives the board layout: the PCB needs plated through-holes with the correct finished diameter for the compliant pin — typically around 0.040" for this pin geometry, but verify against the TE application spec for the specific PCB thickness and copper weight. The 6-row, 16-column grid on 0.075" pitch means trace escape from the inner rows requires blind vias or buried vias in a multilayer backplane.
