ULO-PCB457A is a 2.5mm-pitch EH wire-to-board family with 2 to 20 positions. Select the female cable housing, female crimp terminals and male PCB header as separate components. Vertical and right-angle headers provide different board layouts.
| Component | Configuration |
|---|---|
| Female housing | 2–20 positions; dimension table below |
| Female terminal | Crimp contact; 5.80mm overall length |
| Male vertical header | V/T; 2–20 positions; 3.20mm solder-tail reference |
| Male right-angle header | R/A; 2–20 positions; 3.20mm solder-tail reference |
PCB457A identifies the component family. Specify housing count, terminal quantities and header orientation separately; cable length and assembled cable quantities are unspecified.

The female housing profile shows 6.50mm height, 3.80mm outer width, 3.40mm lower width and a 0.60mm top projection. The terminal drawing includes 2.85mm, 2.05mm and 1.30mm length references, with a 2.01mm cross-section height and 1.00mm/1.60mm widths.
The vertical male header shows a 6.40mm front-body reference, 3.90mm side width, 5.60mm side-body height and 0.64mm contact width. The right-angle version shows 6.70mm front-body height, 4.20mm side width, 6.40mm side-body height and a 2.20mm lower reference. Use the appropriate orientation drawing when checking board clearance.
