Product details

Board Footprint and Signal Count

The 77311-101-24LF: The single row keeps the board footprint narrow: 24 positions at 2.54 mm pitch gives a total width of about 60 mm from pin 1 to pin 24.

Common mating halves include BergStik receptacle housings and IDC sockets from the same series. Termination is solder to through-hole PCB. No press-fit or surface-mount option — this is a traditional solder-in header. Push-pull fastening — no locking latch. In a vibration environment, consider a secondary retention method such as a wire-to-board housing with a latch or a dab of adhesive on the header body.
