Series Overview
The L7 Width 100 sub-series consists of three primary part lengths — 350-100, 500-100, and 650-100 — with a 100 mm secondary part width. Peak force range 4,052 ~ 8,104 N, water-cooled continuous force 1,813 ~ 3,638 N. This is the entry-level high-efficiency, water-cooled iron-core linear motor in the L7 series.
