# Pluggable terminal block header A right-angle PCB header for pluggable terminal blocks, of the Phoenix Contact MSTBA 2,5 type (5.0 or 5.08 mm pitch) or MC 1,5 type (3.81 mm), 2 to 16 positions. Pin 1 is at the origin, the row runs along +X, and the housing sits on the XY plane with its opening facing -Y. The solder pins go down through the board. ## Source Phoenix Contact data sheet, *MSTBA 2,5/ 2-G-5,08* (1757242), a copy at (Phoenix Contact's own site refuses automated downloads): - Dimensions (page 5): length 12, height 8.6 above the board, solder pins 3.5 long. - Dimensional drawing (page 6): width a + 7 (5.0 mm) or a + 7.08 (5.08 mm), and the solder pins 2 from the back face. The data sheet is for the 2-position, 5.08 mm part. Its drawing gives the same housing for both pitches. MC 1,5: data sheet *MC 1,5/ 2-G-3,81* (1803277, German, 10.03.2011), a copy at . Technical data (page 1): length 9.2, pins 0.8 x 0.8. Dimensional drawing (page 4): width a + 5.2, height 7.25, solder pins 3.4 long and 8 from the opening. **Proportions, for looks only:** the MSTBA pin section (1.2), the wall, and the mating pins' reach. The data sheet's side view doesn't dimension the reach, so the pins run to 1.5 mm short of the opening, where the plug's contacts meet them. The plug isn't part of this header. The housing is PA, modelled as `pa6`, green. Vertical MSTBVA 2,5 at 5.08 mm: data sheet *MSTBVA 2,5/ 2-G-5,08* (1755736), Dimensions page 3 of the 24 Feb 2024 edition, a copy at : width 12.16 for 2 positions (a + 7.08), length 8.6, installed height 12, solder pins 3.9 long and 1 x 1. The pins' place, 3.8 from one face and 3.54 past each end pin, is from the July 2003 edition's dimensioned drawing and drilling diagram, page 4, a copy at . Vertical: the opening faces up and the pins stand 1.5 mm below the top. MSTBVA at 5.0 mm, MCV, flanged (GF) and 3.5 mm MC headers aren't here yet; see `COVERAGE.md`.
