ULO-PCB457 is a 2.5mm-pitch XH connector system with 2 to 20 positions. Select the female cable housing, female crimp terminals and male PCB header as separate components. Male headers are illustrated in vertical and right-angle forms with selectable contact kink.
| Component | Selection |
|---|---|
| Female housing | 2–20 positions; white or transparent |
| Female crimp terminal | 28–22AWG wire; tin or full gold-flash finish |
| Male PCB header | 2–20 positions; vertical or right-angle; with or without kink |
PCB457 identifies the family. Individual component suffix numbers and package quantities are unspecified. Specify the housings, terminals and headers needed for the intended assembly.
