# Screw terminal block

A PCB screw terminal block of the Phoenix Contact MKDS 1,5 (5.0 or 5.08 mm pitch), PT 1,5 (3.5 mm) or MPT 0,5 (2.54 mm) type. Pin 1 is at the origin, the row runs along +X, the housing sits on the XY plane with the wire entries facing -Y and the screws on top, and the solder pins go down through the board.

Phoenix Contact data sheet, *PCB terminal block MKDS 1,5/ 2-5,08* (1715721), a copy at <https://uploadcdn.oneyac.com/attachments/files/brand_pdf/phoenixcontact/A4/EA/MKDS152-508.pdf> (Phoenix Contact's own site refuses automated downloads). The data sheet is for the 2-position, 5.08 mm part. Dimensions (page 4):

- width a + pitch, where a is the distance between the end pins
- installed height 13.8, length 9.8
- solder pins 3.5 long and 0.9 x 0.9

The dimensional drawing (page 8) shows the pins 4.6 from the wire-entry face, and the same housing with 5 and 5.08 mm pitch.

- MPT 0,5: data sheet *MPT 0,5/ 2-2,54* (1725656), page 5 and dimensional drawing page 6, a copy at <https://static.chipdip.ru/lib/776/DOC031776037.pdf>: width 5.54 for 2 positions (1.5 past each end pin), height 8.5, length 6.2, pins 3.5 long, 0.5 x 0.9, 3.1 from the back face.

Each data sheet is for one position count; the others follow the drawing's a + pitch rule.

**Proportions, for looks only:** the side profile's step and slope, and the wire entry and screw opening sizes. The screws and clamps aren't modelled. The housing is PA; the part uses `pa6`, green.

The 3.81 mm MKDS, PT 1,5 at 5.0 mm and other makers' blocks aren't here yet; see `COVERAGE.md`.
