Product details

Single-End PC Pin, Gold-Plated

The 1990-2 is a single-end PC pin from Keystone Electronics, pressed into a 0.026" (0.66mm) mounting hole with a knurled press-fit shank. The 0.018" (0.46mm) diameter below the flange carries gold-plated phosphor bronze for the contact surface, with 10.0µin (0.25µm) of gold over the base metal.

Board Thickness and Hole Fit

The pin accepts a board thickness of 0.062" (1.57mm) and requires a 0.026" (0.66mm) mounting hole — the knurled shank holds the pin in place without solder.
