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

> What are Phoenix MSTB 2,5 pluggable terminal header dimensions?

- Category: Electronics › Connectors
- Kind: Standard part
- Basis: KiCad 3D models from Phoenix Contact MSTB 2,5 drawings (COMBICON; generic '2EDG' pluggable blocks match)

## Notes

- 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.

## Questions

**What is the difference between MSTBA and MSTBVA?**

A = horizontal header (plug enters from the board edge), VA = vertical header (plug enters from above). Both take the same MSTB 2,5/..-ST plug.

**What case opening does a 4-position pluggable terminal need?**

About 22.5 × 12 mm for the plug body to pass, plus 15 mm of depth for the wires on a horizontal header.
