Product details

Contact system and plating

The SEI-120-02-GF-S-M-AB is a 20-position compression contact from Samtec's SEI series, non-gendered, single-row, at 0.039" (1.00mm) pitch. Gold plating at 3.00µin (0.076µm) on phosphor bronze contacts suits moderate-cycle signal interconnects where corrosion resistance is required.

Position count across the SEI series

The SEI-120-02-G-S-AB shares the same 20-position count and 1.00 mm pitch but carries a 10.0µin (0.25µm) gold finish, compared to the 3.00µin (0.076µm) on the GF variant — the thicker plating on the G version supports higher mating cycle duty.

Production status and compliance

RoHS3 compliant per the manufacturer's declaration.

Frequently asked questions

What is the difference between the SEI-120-02-GF-S-M-AB and the SEI-120-02-G-S-AB?

Both are 20-position, 1.00 mm pitch SEI series compression contacts. The GF variant has a 3.00µin (0.076µm) gold finish; the G variant has a 10.0µin (0.25µm) gold finish, which provides higher mating cycle endurance.
