Base sections for DIN modules. Simply add section lengths together to obtain the required length of rail for your PCB. 107.5mm PCB width, overall width 112.7mm.
Calculating Total DIN Rail Length
The total PCB length that can be accommodated by a given section can be calculated by totalling up the total length of the base sections and adding 10mm for each endcap. Eg: 2 x 45mm bases and 1 x 11.2mm section + endcaps = 45 + 45 + 11.2 + 10 + 10 = 121.2mm
