Pluggable terminal block headers: Phoenix MSTBA / MSTBVA 2,5 (5.0 / 5.08 mm), 2–6 positions — dimension sheet

Basis: KiCad 3D models from Phoenix Contact MSTB 2,5 drawings (COMBICON; generic '2EDG' pluggable blocks match)
Catalog version: 2026-10-20

Sizes: see table below
- MSTBA (horizontal) and MSTBVA (vertical) headers accept the MSTB 2,5/..-ST plug; 5.08 mm pitch (5.00 mm metric twin). Header height about 8.6 mm; the plug adds ~16 mm and needs a 12 × (n × 5.08 + 2) mm case opening.
- Pin to pin 5.08 mm, pins 1.0 mm diameter; the plug's wire entry is 2.5 mm² max.
- Horizontal headers sit at the board edge and the plug extends outward; vertical headers need 25 mm of clearance above the board for the plug and wires.
