The 3.2 mm E-clip beside the 2.3 mm and the 4 mm

The 3.2 mm is number 2, counting from the smallest, of the 11 DIN 6799 E-clips published here, from 2.3 mm to 15 mm.

• Clip thickness (s): 0.6 mm on the 3.2 mm E-clip, against 0.6 mm on the 2.3 mm and 0.7 mm on the 4 mm.
• Clip thickness, limits (s_lim): 0.58 to 0.62 mm on the 3.2 mm E-clip, against 0.58 to 0.62 mm on the 2.3 mm and 0.68 to 0.72 mm on the 4 mm.
• Mouth width (a): 2.7 mm on the 3.2 mm E-clip, against 1.94 mm on the 2.3 mm and 3.34 mm on the 4 mm.
• Mouth width, limits (a_lim): 2.66 to 2.74 mm on the 3.2 mm E-clip, against 1.9 to 1.98 mm on the 2.3 mm and 3.292 to 3.388 mm on the 4 mm.
• Outer diameter, installed (d3): up to 7.3 mm on the 3.2 mm E-clip, against up to 6.3 mm on the 2.3 mm and up to 9.3 mm on the 4 mm.
• Groove diameter (d2): 3.2 mm on the 3.2 mm E-clip, against 2.3 mm on the 2.3 mm and 4 mm on the 4 mm.
• Shaft diameter range (d1): 4 to 5 mm on the 3.2 mm E-clip, against 3 to 4 mm on the 2.3 mm and 5 to 7 mm on the 4 mm.
• Groove width (m): 0.64 mm on the 3.2 mm E-clip, against 0.64 mm on the 2.3 mm and 0.74 mm on the 4 mm.
