Terminal Block Density
Terminal Block Density is based on the Width of the Terminal Block over a Linear Measurement. The Linear Measurement is usually expressed in the number of pieces per foot or meter.
Example: 8WA1011-1DG11 is 6.5 mm Wide. How many terminal blocks can we get into A) one foot and B) one meter.
1 inch = 25.4 mm; 12 inches = 304.8 mmTerminals per Foot = 304.8 / 6.5 = 46.89 =
46
1 meter = 1000 mmTerminals per Meter = 1000 / 6.5 = 153.85
= 153
