32. OEM Control Components 8WA Terminal Blocks November 2006 32 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 mm Terminals per Foot = 304.8 / 6.5 = 46.89 = 46 1 meter = 1000 mm Terminals per Meter = 1000 / 6.5 = 153.85 = 153 Selection
