# Seven-segment display

Kingbright's through-hole 7-segment LED numeric displays, chosen by part number. The part number gives the package and the emitting colour. The display lies on the board (the XY plane) on the rim of its back, centred on the origin. The digits run along X, upright along +Y, with the face up (+Z) and the pins down through the board. The housing is one solid. Each segment and dot is its own solid on the face, standing 0.03 proud so its edges show. Each pin is its own solid.

Every package has round pins Ø 0.5 (+0.25/-0.1) at a 2.54 pitch, 4 ±0.5 long below the rim. Where the end pin's distance is given, the pin rows are centred on the body (2.34, 1.21 and 13.92 each make it so).

**Proportions, stated plainly.** The drawings show these but don't dimension them:

- The back is a rim around a shallow recess, and the pins leave from the recess. The rim's flat is 0.8 wide on the long sides and at the ends, except CA56-12's ends (1.3) and SBC18-11's ends (3, dimensioned). Its inner wall slopes in over another 0.8.
- The rim depths of CA56-12 (1.75) and DA04-11 (1.2) are measured off their side views against the drawn depth.
- The digits are centred on the body. CA56-12's pin rows are centred on the body, as drawn.
- Segments are six-sided bars with a gap of a quarter of their width at each joint. The digit width is measured across the outer edges at mid-height, and the digit slants about its mid-height.
- A digit's dot sits at its foot. Its centre is 0.569 times the digit width right of the digit's centre, which is DA04-11's dimensioned 3.4 divided by 5.976.
- CA56-12 draws two more dots, DP5 and DP6, as a colon between digits 2 and 3. They are the dot's size, midway between the digits, at 0.79 and 0.46 of the digit height.

**Materials.** The sheets name no materials and give no weight, so the mass isn't checked. The housing is shown as pc with a grey face. The segments are the epoxy-filled diffusers (the sheets warn against stressing "the epoxy resin"), shown as pmma (1.18; epoxy is about 1.2), white diffused and tinted with the emitting colour. The pins are metal, shown as copper.

## Catalogue models

The old catalogue's 17 Kingbright entries have no reference models. Each names an exact Kingbright part number, and each maps to the preset of that number, from that part's own sheet.

The family's other entries name other makers' displays (HDSP, HDSM, LTS, MAN, DE, ELD and KCSC02 parts). They are left with their reasons in `COVERAGE.md`.
