The 0.6 mm split pin beside the 0.8 mm

The 0.6 mm is the smallest of the 6 ISO 1234 split pins published here, from 0.6 mm to 2 mm.

• Pin diameter (d): 0.4 to 0.5 mm on the 0.6 mm split pin, against 0.6 to 0.7 mm on the 0.8 mm.
• Extended prong (a): 0.8 to 1.6 mm on the 0.6 mm split pin, the same on the 0.8 mm.
• Eye length (b): 2 mm (reference) on the 0.6 mm split pin, against 2.4 mm (reference) on the 0.8 mm.
• Eye width (c): 0.9 to 1 mm on the 0.6 mm split pin, against 1.2 to 1.4 mm on the 0.8 mm.
