ULO-PCB457C uses a 2.5mm contact pitch and supports 2 to 20 positions. The family comprises separate female housings, female crimp terminals and male PCB headers. Choose the vertical or right-angle header profile to suit the board layout.
| Component | Configuration |
|---|---|
| Female housing | 2–20 positions; 4.70mm side-width reference |
| Female crimp terminal | 7.60mm overall length |
| Male vertical header | 2–20 positions; 6.0mm body and 3.6mm solder-tail references |
| Male right-angle header | 2–20 positions; 8.0mm overall height and 3.5mm tail reference |
Specify housing and header position counts, terminal quantities and header orientation separately. PCB457C is the family designation; a complete cable assembly and cable length are unspecified.

N is the number of positions, from 2 to 20. Dimension expressions below produce millimetre values. The housing and header drawings both use the stated 2.5mm pitch.
| Component or feature | Dimension |
|---|---|
| Female housing overall length | (N + 1) × 2.5mm |
| Female housing inner longitudinal reference | (N − 1) × 2.5mm + 3.4mm |
| Female housing front height | 9.10mm |
| Female housing side width | 4.70mm |
| Male header overall length | (N + 1) × 2.5mm |
| Male header contact span | (N − 1) × 2.5mm |
| Male contact width | 0.70mm |
| Vertical header side profile | 4.8mm width; 6.0mm body height; 3.6mm tail length |
| Right-angle header side profile | 4.8mm width; 8.0mm overall height; 6.6mm inner height; 3.5mm tail reference |
The female-terminal drawing gives a 7.60mm overall length, 1.60mm and 2.8mm longitudinal references, a 2.1mm cross-section height, 1.00mm and 1.60mm widths, and a 0.4mm lower projection. Match the component profile and orientation when checking the available space.
