90-Position Impact Backplane Header with Guide Left Keying
The TE Connectivity 2007779-1 is a 90-position header from the Impact series, configured as a male-pin, right-angle press-fit connector with Guide Left keying. The 9-row, 10-column grid at 0.075" (1.91mm) pitch delivers a dense signal footprint for backplane and midplane applications.
Signal-Level Ratings Define the Duty
Rated 0.75A per contact at 30VAC/DC, this header is designed for signal-density routing, not power distribution. The 30VAC/DC rating reflects the tight 1.91mm pitch — creepage distance between adjacent pins is the limiting factor, not the contact itself. For a backplane carrying differential pairs or single-ended logic, the current headroom is adequate; for a power rail, a different connector family would be needed.
Press-Fit Termination for Solderless Assembly
The press-fit termination means the header is inserted into a PCB with plated through-holes using a pneumatic or hydraulic press — no wave soldering, no hand-solder touch-up. The compliant pin design provides a gas-tight interference fit that meets the reliability requirements of telecom and data-center backplanes. The through-hole mounting anchors the connector against the insertion and extraction forces of repeated daughtercard mating cycles.
The connector is RoHS Compliant.
