VN.ST20

400 Vac | three-phase

400 Vac gear motor with quick release and 1/20 reduction rates | New plastic box that makes wiring the motor easier, thanks to the position of the front clip connector and the possibility of reaching three different positions with the wiring | Two accessories are available for chain drives with reduction rates 1:1 (off-axis motor installation) or 1:1.8 (torque or speed multipliers) | Easy and precise adjustment of limit switch position |Maximum safety guaranteed during rapid release phases, thanks to a micro-switch that cuts the power supply to the motor | Oil lubricated reductions with hardened steel screw and bronze gears guarantee high performance, maximum reliability and silent operation | 4 micrometrically adjustable limit switches
