Product details

2.54 mm pitch, 2 positions — footprint and fit

The 77311-424-02LF: Two positions, all loaded — this is the minimum position count in the BERGSTIK® series, often used for jumper or single-signal-pair routing. The 0.266" (6.75 mm) mating pin length and 0.114" (2.90 mm) solder tail give a through-hole stack height that clears most single-board assemblies.

Tin plating — where it works and where it doesn't

Tin is the cost-effective choice for moderate mating cycles — expect 50–100 cycles before fretting wear becomes a concern.

Frequently asked questions

Is 77311-424-02LF shrouded or unshrouded?

Unshrouded — no shroud around the pins, so it mates with standard unshrouded receptacles. No keying or latch; alignment depends on the board-to-board fit.
