Product details

It accepts female blade sockets in a single row, with all 5 positions loaded for pure power delivery — no signal contacts. The right-angle orientation and board-edge mounting put the power path perpendicular to the PCB, which is the typical layout for a plug-in card feeding a backplane bus bar.

Press-Fit Termination — No Solder, No Rework

The press-fit termination is the defining feature here. Instead of solder, the compliant pin compresses into the plated through-hole, creating a gas-tight joint. That means no solder voids, no wicking, and no rework — the connector is pressed into the board in one operation. For a backplane assembly with dozens of connectors, press-fit eliminates the thermal stress of wave soldering and makes field replacement of a damaged connector feasible: desolder a 5-position power header from a multi-layer backplane and you risk lifting the barrel. Press-fit pins pull out cleanly with the right tool. Board layout needs clearance behind the connector for the press tool anvil — typically 3-5 mm of keep-out on the opposite side.

The blade power contact style is a standard TE UPM format — the female socket blades accept the male tabs from the header. The single-row, 5-position layout is keyed by the housing geometry; there is no secondary keying option in this series. Confirm the header part number from the same UPM family to ensure the blade width and pitch align.

Frequently asked questions

What is the mounting style of 120943-3?

It uses press-fit termination with a right-angle board-edge, through-hole mount. The connector is pressed into plated through-holes at the edge of the PCB, no soldering required.

Does 120943-3 have a press-fit termination?

Yes, the 120943-3 uses press-fit termination. The compliant pins create a gas-tight joint in the plated through-hole without solder.
