(1) Comparison of Dimensions
The following table shows comparison of the MR-J3 series and MR-J4 series dimensions.
The two are the same in height, width, mounting screw pitch, and screw size, and therefore compatible in
mounting. When the servo amplifier is mounted so that the heat sink is inside the cabinet, the depth vary.
